Exponential Growth | In which a quantity increases at a fixed percentage per unit of time, such as 2% per year. |
Environment | The sum total of all living and nonliving things that affect any living organism |
Environmental Science | An interdisciplinary study that integrates information and ideas from the natural sciences(such as biology, chemistry, and geology) that study how humans and their institutions interact with the natural world. |
Ecology | a biological science that stuies the relationships between living organisms and their enviroment |
Environmentalism | A social movement dedicated to protecting the earths life-support systems for us and other species. |
Sustainability/ Durability | The ability of earth's 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. |
Solar Capital | Energy from the sun that warms the planet and supports photosythesis. |
Trade-off | A compromise to try to reEcostore degraded or cleared natural capitals (replant trees) |
Sound Science | The concepts and ideas that are widely accepted by experts in a particular field of the natural or social sciences. |
Economic Growth | An increase in the capacity of a country to provide people with goods and services. |
Gross Domestic product (GDP) | The annual market value of all goods and services produced by all firms and organizations, foreign and domestic, operating within a country. |

Developing countries | Middle-Income, moderately Developed Countries (China, India, Brazil, and Mexico) |
Environmentally sustainable economic development | The goal is to use political and economic system to encourage environmentally beneficial and more sustainable forms of economic development and discourage envirometally harmful and unsustainale forms of economic growth |
Resource | Anything obtained from the environment to meet our needs and wants. |
Perpetual Resource | It is renewed continuously on a human time scale. |
Renewable resource | Can be replenished fairly rapidly (hours to several decades) through natural processes as long as it is not used up faster than it is replaced. |
Sustainable Yield | The highest rate at which a renewable resource can be used indefinitely without reducing its available supply. |
Environmental Degradation | When we exceed a resource's natural replacement rate, the available supply begins to shrink. |
Common-property/ Free-access resources | Resources that no one owns and are available to users at little or no charge(air, open ocean etc) |
Tragedy of the Commons | In 1968, biologist Garret Hardin called the degradation of renewable free-access resources Tragedy of the Commons |
Ecological footprint | The amount of biologically productive land and water needed to supply an area with resources and to absorb the wastes and pollution produced by such resource use. |
Per Capita Ecological Footprint | The average ecologial footprint of an individual in an area. |
