Across
- 3. The circulation of chemicals necessary for life from the environment THROUGH organisms and back to the environment.
- 5. A resource that provides a continuous supply of energy. ex: the sun (lasts for <6 billion years)
- 12. Direct radiant energy from the sun and a number of indirect forms of energy produced by the direct input of such radiant energy.
- 17. Processes provided (free of charge) by healthy ecosystems.
- 18. A condition in which people are unable to fulfill their basic needs for adequate food, water, shelter, healthcare, and education.
- 19. View that states that humans can and should manage the earth for our benefit, but that we also have an ethical responsibility to be caring and responsible managers of the earth.
- 21. Single, identifiable source of pollution.
- 23. View that states that humans are separate from and in charge of nature, that nature exists mainly to meet our needs and increasing wants, and that we can use our technological advances to help control earth’s-life support systems to better our future.
- 24. A mathematical equation used to calculate the exponential growth of the human population or any other factor(s).
- 25. The variety of genes, organisms, species, and ecosystems in which organisms exist and interact.
- 26. Lessons from nature that focus on biodiversity, chemical cycling, and solar energy.
Down
- 1. Everything around us. Includes living and nonliving things with which we interact in a complex web of relationships that connect us to one another and to the world we live in.
- 2. A resource that can be replenished by natural processes as long as we do not use it faster than it can renew itself. ex: trees.
- 4. The environmental degradation of shared renewable resources such as grasslands and forests.
- 6. Guidelines for living sustainably derived from the studies of economics, political science, and ethics. These principles contain “full-cost pricing”, “win-win solutions”, and “a responsibility to future generations.”
- 7. Dispersed sources of pollution, hard to identify.
- 8. The amount of land and water needed to supply a person or an area with renewable resources such as food and water, and that are needed to absorb and recycle the wastes and pollution produced by such resource use.
- 9. Natural resources are materials and energy in nature that are essential or useful to humans.
- 10. View that states that humans are all part of, and dependent on, nature and that the earth’s life-support system exists for all species, not just us.
- 11. A country that is not developed due to its low gross national income, its weak human assets, and its high degree of economic vulnerability.
- 13. A resource that exists in a fixed quantity within the earth’s crust. ex: coal.
- 14. Depletion or destruction of a potentially renewable resource such as soil, grassland, forest, or wildlife that is used faster than it is naturally replenished.
- 15. A country that has a highly developed economy and an advanced technological infrastructure.
- 16. An interdisciplinary study of how humans interact with the living and nonliving parts of their environment.
- 20. The natural resources and services that keep us (humans) and other species alive and support human economies.
- 22. Contamination of the environment by a chemical or other agent such as noise or heat to a level that is harmful to the health, survival, or activities of humans or other organisms.
