Plotted usually results in a J-curve. Example: human population Environment- everything around us; all external conditions and factors, living and nonliving (chemicals and energy), that affect any living organism or other specified system Environmental science- Interdisciplinary study that uses information and ideas from physical sciences along with those from social science to learn how nature works, how we interact with the environment, and how to deal with environmental problems. Ecology- Biological science that studies the relationship between living organisms and their environment; study of the structure and functions of nature Ecosystem- Community of different species interacting with one another and with the chemical and physical factors making up its nonliving environment Environmentalism- a social movement dedicated to protecting the earths life support system for humans and other species. Sustainability- Ability of earths various systems, including human cultural systems and economies, to survive and adapt to changing environmental conditions indefinitely. Natural capital The natural resources and natural services that keep us and other species alive and support our economies. Nutrient cycling Circulation of chemicals necessary for life from the environment through organisms and back to the environment. Natural resources materials and energy in nature that are essential or useful to humans. Natural services processes of nature, such as purification of air and water and pest control, which support life and human economies. Solar capitol Solar energy that warms the planet and supports photosynthesis, the process that plants use to provide food for themselves. Indirectly produces forms of renewable solar energy such as wind and flowing water. How long will the sun last? 6 billion years Photosynthesis Complex process that takes place in cells of green planets. Radiant energy from the sun is used to combine carbon dioxide and water to produce oxygen....
