Environmental Health & Making Decisions
(middle grades)

Activity, lesson plans, & supporting materials

Overview

This is a unit plan for student's to review and facilitate their understanding of the effects of the environment on health. This includes beneficial and detrimental environmental affects on health and how influences impact the decisions people make. Reasoned decisions and decisions made subconsciously and emotionally without sufficient critical thinking.

Human's interactions with the environment determines their quality of life, life expectancy, and health. The World Health Organization (WHO) defines environment, as it relates to health, as

“all the physical, chemical, and biological factors external to a person, and all the related behaviors.” Source page 22.

Environmental health is the study of how the environment affects human health and disease. The natural and human made, built, environments can be described by six variables:

  1. Air
  2. Water
  3. Earth - Food production, transportation, shelter (temperature and habitat)
  4. Energy
  5. Human health
  6. Social: education, economics, government policies, laws, and the EPA (Environmental Protection Agency), entertainment

“Environment,” in this context, means things in the natural environment like air, water and soil, and also all the physical, chemical, biological and social features of our surroundings. The man-made, or “built,” environment includes physical structures where people live and work such as homes, offices, schools, farms and factories, as well as community systems such as roads and transportation systems, land use practices and waste management. Consequences of human alteration to the natural environment, such as air pollution, are also parts of the man-made environment. The social environment encompasses lifestyle factors like diet and exercise, socioeconomic status, and other societal influences that may affect health. – National Institute of Environmental Health Science

Activities include a four step process to create a model of nature and human activities. The model is then used to develop a comprehensive list of the six environmental health variables and human impacts. Which, are used to understand the complexity of environmental health and appreciate how difficult it is to make environmental decisions. The model and list are used to review historical environmental disasters, technological decisions, and then used with a decision making process, to analyze personal decisions, their effects on the environmental health, and influences that affect those decisions. Lastly, students will make a poster, video, or skit to suggest how to positively affect environmental health related to their personal decision.

Related study topics:

  • Investigate environmental health, related to social science issues such as: government and economics: laissez-faire, Adam Smith’s invisible hand, capitalism, capitalist socialism, socialism, and other world economies and politics. Relating their relationships to decision making for healthy environments.
  • Science related investigations. Air, water, land quality investigations

Inventions

Activity: 1b, & 1c, 1d

Activity 1b

Review information students brainstormed and wrote on lab sheet for activity 1a and compare it to the information added on lab sheet for activity 1b.

Discussion points:

  1. What is nature? Nature is everything in the universe, living and nonliving ...
  2. What sustains life on Earth? Environmental factors.
  3. What are environmental factors? All objects that affect life. Air, water, habitat for shelter to maintain temperature, earth, food, gravity, ...
  4. What relationships are in nature? Oxygen - carbon dioxide cycle, Water cycle, Life cycle for each species of organisms, nitrogen cycle, energy cycle or food cycle.
  5. What is the relationship of organisms in nature? Forming an interconnected ecosystem to sustain life on Earth.
    • Carbon Dioxide - Oxygen Cycle plants use of carbon dioxide with sunlight to make simple sugar (C6H12O6) for food and release oxygen as a waste gas. The process generally happens in leaves where sunlight is absorbed, oxygen enters, and carbon dioxide exits.
    • Energy cycle is a process that sustains life on Earth. Plants combine sunlight, carbon dioxide, and water through photosynthesis to make sugar (C6H12O6) to use for energy to live. Plant consumers (herbivores) consume plants for their energy, animals (omnivores & carnivores) consume plants and animals for their energy and decomposers decompose living things for their energy and their waste recycles as environmental factors.
    • Life cycle is the process of change each organism undergoes from life to death including most importantly reproduction to sustain the species.
    • Nitrogen cycle is the continuous process where nitrogen, in different chemical forms, passes from the atmosphere, to organisms, soil, and water back to the air to sustain life on Earth. Exchange happens with rain, decomposition, bacteria and plant metabolism, fixation, ammonification, nitrification, and denitrification.
  6. What is the purpose of organisms in nature? Good question. An answer would depend on a personal philosophy. From a human centered or (narcissistic) point of view it would be to sustain human life. From an ecosystem point of view life sustains life through interconnections and the energy cycle.
  7. What are consumers, plants, decomposers?
    • Consumer is an organism that gets its food by feeding on other organisms or organic matter. Unable to produce its own food like plants.
    • Plants are multicellular organisms that produce their own food with photosynthesis.
    • Decomposers are organisms whose ecological who feed on dead or decaying organism, which recycle nutrients.
  8. How does water, energy, oxygen-carbon dioxide, cycles function for the benefit of life? Cycles provide the reuse of matter and energy required for life.
  9. What are ecosystems and communities?
    • Ecosystems include all the living organism and nonliving substances within a defined area. Could be the entire Earth or any smaller area on Earth or in the Universe.
    • Communities are all the living organisms within a selected area.
  10. What are habitats? Habitats are the places organisms or populations live.

  3. What have humans added to nature? Habitat for humans, nitrogen, carbon dioxide, plastic, houses, malls, factories, farms, mined ores, roads, airports and shipping ports, computers ... a total of 30 trillion Tons of stuff. Source
  4. What environmental changes have been made since humans settled?
    • How have humans changed and built on Earth? houses, malls, factories, farms, cities, roads, airports and shipping ports ...
    • What artifacts do humans add to the environment? All our stuff. 30 trillion tons ...
    • What habitats, communities do humans add or change? cities, farms, ranches, houses, apartments, skyscrapers, shopping malls, zoos, game preserves, barns, parks, national parks, state parks, ...
    • What human activities affect the environment? Everything we do.
  5. Ask students for their reasons for where they put humans on their model. Compare their placements to the placements on 1c. Humans are living organisms and should be in the trapezoid as living and in either animal or plant consumers or both depending on what their diet is.
  6. Are all human needs for survival, good health, and good living provided through nature? Yes, in a healthy environment. However, there are environments or ecosystems do not provide enough for humans to survive. South Sudan 2017.

Activity 1d

  1. After students understand information on lab sheet 1c tell them to list human created artifacts or altered habitats to the model of nature and information to answer this questions.

Exploration

  1. Put students in groups, focus their attention, and assess their initial understanding of the first three focus questions. Do not discuss the focus questions with the class. Move on to the Invention and discuss them after the Environmental impacts of humans ... activity.
    1. In general how do humans affect environmental health?
    2. How have humans changed environments on the Earth?
    3. How have changes humans made to nature helped, limited, or hurt their health?

Invention

  1. Review the first three focus questions and include the six environmental variables as appropriate: 1. Air 2. Water 3. Earth - Food production, transportation, shelter (temperature and habitat) 4. Energy 5. Human health 6. Social: education, economics, government policies, laws (Environmental laws), and the EPA (Environmental Protection Agency), entertainment
    1. In general how do humans affect environmental health? Humans can affect environmental health in three ways: Improve it, decrease it, or have no affect.
    2. How have humans changed environments on the Earth? Earth's environments often attain a balance so the organisms can live in a sort of equilibrium. People who lived many thousand years ago and survived as hunters and gatherers were able to do so as long as their numbers were small enough so the animals and plants were able to survive the people's harvest (EARTH - food production, SOCIAL - hunting, herding, farming). As people increased over hunting could create unhealthy environments and may have caused the extinction of animals (mammoth and aurochs) (EARTH - food production, SOCIAL - hunting, herding, farming). As people increased in numbers their use of water and land could deplete their availability (lack of WATER desertification, over grazing of animals, soil erosion, land, EARTH ... ) sufficiently to sustain people in a particular environment. As people increased their numbers the elimination of their wastes became a health problem (sanitation for the disposal of garbage, human waste, animal waste, chemical waste, solid waste, ... (AIR - smell, WATER, EARTH - land)).
    3. How have changes humans made to nature helped, limited, or hurt their health? Hunting can decrease animal populations to sustain or decrease those populations. A healthy animal population will provide a healthy food supply (EARTH - food) which will be healthy for humans. Similarly humans land use for animal herds and farming can conserve land and water or deplete land or water which will directly affect human health relative to food that can be harvested (WATER, EARTH - food, SOCIAL organize for irrigation, waste removal). Adding chemicals to the environment at a rate that can be decomposed without overwhelming a healthy environment will also be healthy for humans (HUMAN HEALTH, AIR, WATER, EARTH - LAND). Or chemicals that will not decompose (plastic, some pesticides, ... ) or in quantities that will not decompose in a timely fashion (fertilizers, coal ash, exhaust, ...) will make the the environment unhealthy which will be unhealthy for humans (HUMAN HEALTH, AIR, WATER, EARTH - LAND, SOCIAL).
  2. Either display or give a copy to students of the Environmental impacts of humans with nature and the affects on health fact sheet, have them review it, and select one of the items on the list to investigate.
  3. Assign students to pairs or triads.
  4. Tell them their investigation should be limited to two minutes. It should include the information on the list, pictures, effects on any of the six environmental health variables (1. Air 2. Water 3. Earth - Food production, transportation, shelter (temperature and habitat) 4. Energy 5. Human health 6. Social: education, economics, government policies, laws (Environmental laws), and the EPA (Environmental Protection Agency), entertainment), locating on a map where the event took place, and any other interesting and relevant information.
  5. Investigate
  6. Students report ... Encourage students to take notes. May require 3 or more written.
  7. Facilitate student's understanding of our needs for survival, good health, and good living provided through nature and the positive and negative affects they have on the quality of the environment. Negative affects, when small, can, usually be over come by the environment in time. However, large changes will take longer to recover from and in some cases may not be possible (animal extinctions, desertification, ...
  8. Summary questions
    1. From all the reports. Select a substance (oil, chemicals, food, water, air ...) or event (war, weather, nature ...) that affects the environment, describe positive and negative changes the substance provides humans, and explain how each has helped or hampered human survival, health, and quality of life?
      • Nuclear energy, bomb, radiation - provided energy in nuclear power plants, nuclear medicine, and understanding nuclear physics. Questionable if provided security from wars. Negative would be those killed in Nagasaki and Hiroshima, and others killed and made ill with radiation from nuclear testing and accidents.
      • Chemicals have been used to create products that make life easier, better, or more healthy. Accidental spills or other disasters have killed and harmed humans and polluted the environment. Environments may be cleaned and in time return to a more healthy situation depending on the type of chemical.
    2. How do we decide environmental health issues? Since we may never be able to be 100% sure on the environmental impact human actions may have on the environment and ultimately on human health we must constantly ask questions and collecting information about the environmental quality. Particularly the six variables important for survival. (1. Air 2. Water 3. Earth - Food production, transportation, shelter (temperature and habitat) 4. Energy 5. Human health 6. Social: education, economics, government policies, laws (Environmental laws), and the EPA (Environmental Protection Agency)
    3. What has happened historically when people ignore the health of the environment? In the prehistoric times much of the time things went on as usual with normal seasonal changes and fluctuation of animal and plant populations. At times there could be severe weather, earthquakes, floods, hurricanes, and other natural disasters. As population increased and people grouped together in cities there could be agricultural related crises that led to extreme failures and possible mass starvation.

Nine steps decision making for environmental health decisions

Topic: Vehicle (car or truck) purchase...

Ask and discussion each decision making step for the topic.

  1. Focus on making a decision and enter a good frame of mind:
    • Remind myself not to go with your gut and not to react without thinking.
    • Decide on decision making steps. For example, 9 step process. Sample circular worksheet: Focus desire of a positive process, identify a problem, collect information, analyze the information, generate options or choices, consider consequences, make a decision, implement, evaluate.
    • Identify who can assist or influence the decision making process and determine if their help or influence would lead to success or block success.
    • Remember to care about the dignity and worth of others during the process by listening to discover their views and explanations so as to avoid confusion or intimidation while assisting understanding and directing the decision making process so it will be beneficial for me, others, and the Earth.
  2. Identify and describe the problem or opportunity:
    • State the problem in a simple singular question or statement.
      • Simple questions: Should I buy a car or truck? What kind of car (or truck) should I buy? What do I like? What do I need more? What would provide more opportunities?
    • State a more complicated question or problem that includes your top priorities.
      • For example. Priorities: Transportation, cost, quality, environment...
      • What vehicle will provide the transportation I need in the best combination of being economical (cost & quality) and environmentally healthy?
  3. Gather information related to the problem or opportunity:
    • Identify related past experiences. - What have I ridden in most? What did and do my relatives and friends drive?
    • List advantages and disadvantages - Make a list of desirable points to consider and rate for each vehicle.
      • Put the name of each possible vehicle at the top of a list. Then, research and rate each point.
      • Identify resources for research: parents, friends, Consumer reports, Blue book, salespeople, ... and gather information such as:
        • Initial cost, interest rate, payments, fuel mpg, upkeep costs, insurance rates,
        • Review the materials used to make the vehicle. Durability ...
        • Identify safety features. - air bags, anti-lock brake system, rear view camera, emergency braking, anti skid control,
        • Other categories would depend on preferences or the variety of vehicles considered. For example if trucks and cars were were both considered instead of all cars or all trucks, then different categories might be needed. Such as:
          • easy to drive (cars are usually easier because mostly they are smaller and easier to park while trucks are larger and harder to drive and park)
          • number of passengers and passenger space
          • truck cab size Vs. cargo bed size Vs. size of vehicle
          • family friendly
          • luggage inside not outside
          • seating comfort
          • visibility (lower to the ground harder to see)
          • cargo space
          • power for towing, hauling, and off road
          • engine power
          • durability
      • Review the information and when you are satisfied it is comprehensive enough, move to analysis.
  4. Analysis of information gathered
    • Identify who can assist or influence the analysis and lead to success or block success.
    • Decide what information is relevant and accurate. Eliminate bias and opinion.
      • Review the list for each vehicle cross inaccurate, biased, and other unhelpful information.
      • Rate each vehicle in each column (3-best, 2-ok, 1not good) or rate each vehicle from top to bottom.
  5. Generate a variety of possible options or choices
    • List different choices. Recall from past experience and listening to others.
    • Be creative and positive.
      • Select top two rated vehicles.

    • Summarize positive and negative consequences for each option.
    • Communicate the main idea and consequences of each option with examples. Check for accurate communication of all facts, definitions, relationships, counter examples, and other necessary descriptive information.
      • Use the list generated for the top two vehicle ratings and list positive and negatives for each.
  7. Evaluate and decide on an option and process for implementation
    • Check the accuracy and comprehensiveness of the consequences for each choice or option and evaluate the feasibility, acceptability and desirability of each.
    • Judge the credibility of the expertise of people used as sources, or any conflict of interest, if there is agreement or corroboration among sources, and if there is a bias effect based on their reputations.
    • Check the accuracy of the procedures used to derive reason and explanation.
    • Check the quality of reasoning, logic, and explanations. See reasoning and proof explanations and example.
    • Determine the risks of making or not making this decision and the probability of success.
    • Determine what criteria should be used to judge and evaluate each option. Could create a matrix and assign a value for each criteria to summarize and review.

  9. Evaluate the implementation: Review and decide to continue with the implementation, alter it, or stop it and try again.
  1. Let students select their topic, investigate, and complete a 9 step decision making process in outline format or the circular format.
  2. Step four of the decision making process is analysis of information gathered, which includes an analysis of influences on the information collected. To decide what is fact or fiction, fact or opinion, biased or impartial so information used is accurate and relevant.
  3. Review the categories of influence on the Circles of Influence Diagram.
  4. Identify influences in each category for purchase of a vehicle. The examples are general, but students should be encouraged to make specific ones based on their experiences.
    • Self influences: personal choice in types of vehicle and need to be responsible.
      • Like a comfortable seat that is high enough to be able to see the road.

Civilization Failures and Environmental disasters
- Fact sheet -

Now and through history humans seek and build healthy environments to provide necessary resources to survive and thrive. At times it has been a struggle for individuals and groups of families, tribes, communities, cities, states, nations, leagues of nations, trade organizations, global treaties, and many other organizations in different combinations to insure their survival, good health, and better living.

While humans have survived and thrived (as determined by the 7+ billion humans on Earth) there have been setbacks: wars, natural disasters, crop failures, exterminations, extinctions, desertification, environmental disasters, and other catastrophes. We need to recognize peoples' demands sometimes exceed what the environment is capable of producing to sustain people in those environments. This can result in the fall of a civilization or the necessity to migrate from an unhealthy environment, for those able to leave, and seek resources elsewhere.

Some civilizations we know failed:

  • Akkadian Empire,
  • Hittite Empire,
  • Minoan settlements on Crete 2700-1450 B.C.E. Weakened by earthquake and maybe conquered by outside forces Source

Environmental health variables and human impacts

The condition of environmental health is complicated. Earth is a global natural environment with many local environments of all sizes and boundaries that overlap other local environments. Additionally humans have built environments of different sizes which can be isolated from natural environments and contained within natural environments.

This makes environmental health, which is complicated to start with, even more difficult to understand. Even with a lot of study one can never be sure of a complete understanding. However, environmental health depends on decisions people make. Individual and collective actions between, and among people and the environment. Decisions on materials, ideas, strategies, policies, and technologies used to survive and create our ideas (philosophies) of a good life determines our environmental health.

To believe an action will have no major affect or not to consider one, could be devastating. Therefore, people need to consider many variables when making decisions. Any change to one variable may have a small effect or one large enough to cause the extinction of one or more organisms. Therefore, deciding variables to consider is essential and must be extensive so as not to omit one that may be important. Even then different people will interpret and apply them differently.

The following list of variables is created for the purpose of making better decisions for healthy environments.

Air, Water, Earth - Food production, transportation, shelter (temperature and habitat), Energy, Human health, and Social: education, economics, government policies, laws (Environmental laws), and the EPA (Environmental Protection Agency), entertainment.

Historical Decisions & their affects on environment health - Fact sheet -

How do we make decisions that result in healthy environments?

Some people look at modern disasters and suggest technology is the problem. If that is true, what should we get rid of or limit? What modern conveniences: medicine, food production, shelter with climate control, education, entertainment, transportation, or other?

If we think it might be a good idea to turn back the clock on technology, or accept a previous era of technology we might consider what happened on Easter Island.

Easter Island had no human inhabitants until around 1000 years ago when people beached their boats on the 66 square mile island that had palm trees and grasslands. People were able to fish and farm and their numbers increased into the thousands. However, in 1722 when Europeans arrived there were less than a thousand. What caused the human population to decline along with the extinction of several species of birds and sea mammals? The decline is a mystery. Was it years of drought, slash and burn farming, increased population demands, rats, or combinations of these or other factors? Read the article - What Happened On Easter Island — A New (Even Scarier) Scenario. by Robert Krulwich; NPR; December 10, 2013, for more information about this mystery.

It seems a limited use of technology can cause unhealthy environments just as a lot of technology use can cause disastrous situations.

So can we learn to use technology in a way that supports a health environment?

To investigate this question, consider innovations and decisions and their impact on environmental health.

Some significant innovations. Fire, domestication of animals, agriculture, wheel, money, metal/nail/steel, printing press, lens, compass, gun powder, vaccination, steam engine, light bulb, telegraph, combustion engine, electricity, antibiotics, airplane, rocket, nuclear fission, birth control, computer, Internet.

Some decisions related to innovation.

  • Lens, telescope, ... Decision to investigate space. Understood the Earth as round with the Sun at the center of the Solar System. Helped understand the causes of seasons to make better weather and astronomical predictions.
  • Lens, sanitation, microscopic, vaccination, ... Decision to develop procedures for better sanitation, develop food preservation processes (pasteurization, canning), use a germ theory for medicine, develop and test vaccines and antibiotics.
  • Steam engine. Decision to use steam engines in place of people and animals for work. Luddites (English workers) who destroyed textile machines and steam engines because they believed the machines and engines threatened their jobs. Proclaiming cloth should be made in a more natural way with human hand labor.
  • Electricity, steam engine, fire, generator, coal, oil, nuclear fission, Decision to build power plants to generate and deliver electrical power.
  • Decision to shun modern technology such as electricity, telephones ... and live without modern technology. Amish and other groups
  • Decision to remove human involvement in certain environments. Theodore Roosevelt created the National Park system.
  • Nuclear fission. Decision to develop nuclear weapons to use in war F.D. Roosevelt. Harry Truman okayed the use of atomic bombs on Hiroshima and Nagasaki.
  • Chemistry, Decision to use of DDT killed insects and didn't seem to harm humans and other animals in the short term, however, its storage in organisms adds up and harms organisms up a food chain. First time ideas of long term effects becomes understood and accepted by many people.
  • Decision to continue as usual and assume there is one cause for bee decline. Bees
  • Decision to continue to develop and use robotic devices with little consideration of ... Driver less cars. Advantages & disadvantages
  • Decision to continue to develop and use artificial intelligence with little consideration of ... and advantages & disadvantages ...

To determine positive and negative effects on environmental health is not always possible. However, we can and must consider possible effects and consequences based on evidence and reasoning to try to make and implement good decisions.

Particulate matter is small pieces of solid or liquid or a combination of both kinds of matter small enough to travel in the air and therefore, can be inhaled by people. Particle size ranges from 0.005 micrometer to 1.0 micrometer (1 micrometer (µm) is one millionth of a meter).

Particulate matter is the greatest health threat because it travels deep into the lungs and embeds in the lung tissue. Particles small enough to not only penetrate the lung alveoli, but penetrate blood vessels. Where they enter the bloodstream and can travel to other body systems and organs: such as the cardiovascular system, liver, and kidneys, and affect them.

Numerous studies have linked elevated particle levels in the air to increased hospital admissions, emergency room visits, asthma attacks and premature death for those with respiratory problems. Children are more susceptible than healthy adults because their lungs and respiratory systems are developing and may thus increases the frequency of childhood illnesses and reduced lung function.

Gasoline, Diesel, E10 - Fact sheet -

Gasoline

Gasoline vapor and exhaust contributes to air pollution and can affect health negatively both as a vapor and after combustion, as exhaust. Gasoline contains more than 150 chemicals, the exact content depends on: geography, season, octane rating, crude oil source, and production method. Benzene, lead, and sulfur are recognized among some of the most harmful chemicals.

Gasoline vapor and engine exhaust can be inhaled, absorbed through skin, and ingested as particulate matter. All harmful depending on the amount of exposure.

People usually have minimal vapor exposure when fueling vehicles at gas stations.

Effects of exposure to higher vapor concentration and exhaust depend on the kind of gasoline burned, the kind of engine, exhaust system, operating conditions, and other factors. Exposure occurs when working near running engines, exhaust in traffic, mowing grass, and walking or waiting along busy streets. Vapors and high level of particulate matter have toxic chemicals that are linked to respiratory illness and irritated lungs, cardiovascular symptoms, harmful neurological effects (dizziness and headaches), and serious effects such as coma and respiratory arrest.

Forty acres of leaves, stalks, roots, and other plant parts was buried millions of years ago with enough pressure, heat, and time to be converted into one gallon of gas. Imagine stuffing that many corn plants into a gas tank to drive 20 miles.

Diesel

Diesel fuel combustion contributes to significant air pollution and can affect health negatively.

Diesel engine emissions vary greatly depending on: type of fuel (composed of hundreds of chemicals), type of engine (locomotives, marine vessels, heavy-duty equipment, trucks...), age and condition of the engine, and how it is operated.

Diesel exhaust includes gaseous compounds and 100 times more particulate matter than gasoline engine exhaust. These exhaust particles have a carbon core which can absorb organic compounds, nitrates, sulfates, oxides, metals and other trace elements. Creating compounds such as: nitrogen oxide, carbon monoxide, formaldehyde, acetaldehyde, benzene, polycyclic aromatic hydrocarbons, nitropolycyclic aromatic hydrocarbons, and more.

Short-term exposure to diesel exhaust can have immediate health effects: severely irritate the eyes, nose and throat, produce bronchial and respiratory problems, and cause coughs, headaches, light-headedness and nausea.

Chronic and long-term exposure to diesel exhaust can increase or worsen allergic reactions, cause inflammation in the lungs, aggravate chronic respiratory symptoms and increase the frequency or intensity of asthma attacks.

People with emphysema, asthma and chronic heart or lung disease are especially sensitive to particle pollutants in diesel exhaust.

E10

The comparison of health risks between E10 fuel and conventional gasoline found no substantial differences in the predicted health effects for the compounds tested.

Carbon dioxide (CO2) is a colorless, odorless gas produced by burning carbon products (oil, gas, coal, wood, ...) and by metabolism / respiration (plants and animal use of food for energy). The near Earth atmosphere has about 0.04 percent and is used in photosynthesis by plants to make food. See carbon dioxide - oxygen cycle below.

Carbon monoxide (CO) is a colorless gas created with incomplete burning of carbon fuels (natural gas, coal, wood, oil, gasoline, ethanol, ... ) and other chemical processes. It is deadly at high concentrations by preventing sufficient oxygen for body tissues to survive.

Carbon Dioxide - Oxygen Cycle is plants use of carbon dioxide with sunlight to make simple sugar (C6H12O6) for food and release oxygen as a waste gas. The process generally happens in leaves where sunlight is absorbed, oxygen enters, and carbon dioxide exits. See chart below and NASA Video: Following atmospheric carbon dioxide (1:35)

Energy cycle is a process that sustains life on Earth. Plants combine sunlight, carbon dioxide, and water through photosynthesis to make sugar (C6H12O6) to use for energy to live. Plant consumers (herbivores) consume plants for their energy, animals (omnivores & carnivores) consume plants and animals for their energy and decomposers decompose living things for their energy and their waste recycles as environmental factors.

Gravity holds everything on Earth and enables air in the atmosphere, water in the atmosphere and surface, soil, and organisms to exchange chemicals through various cycles.

Greenhouse effect in an actual greenhouse is caused when sun light shines through the glass and warms everything inside the greenhouse. The heat increases as the glass slows the heats escape. With the greenhouse effect outside the Earth's atmosphere acts as the glass. During the day, the Sun shines through the atmosphere and warms the Earth's surface. At night, Earth's surface cools and heat flows into the atmosphere and out towards space. However, as it does it can interact with particles in the atmosphere (carbon dioxide, methane, water vapor, water droplets, and particulate matter) that act like glass and slow the flow of heat into space. Eunice Foote, demonstrated the greenhouse effect and described her results in the 1856 issue of Scientific American. titled Scientific Ladies. 9, 1856.

Hazardous waste incineration. Is a process to reduce the danger of hazardous waste with heat. Process: Waste is tested to determine what it is to determine how to process it. Then it enters a rotary kiln and is incinerated (burned) at about 1,000 °C (1832° Fahrenheit). Next, it moves to another chamber to insure a more complete burn. Separation begins with removing waste ash and noncombustible solids. Then gases and particulate matter are processed by spray drying (removes particulate matter, salts, and some metals) and wet scrubbing (removes sulfur dioxide, acids, and halogen). Followed by active carbon treatment (dioxins, furans, and mercury), and catalytic reduction (nitrogen oxides). The process reduces the amount of waste, however, the toxic materials become concentrated and need to be safely disposed.
