Environmental science

Ecology

1. the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.

Renewable resource

A renewable resource is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere.

Non-renewable resource

A resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years.

Developed country

Economic criteria have tended to dominate discussions. One such criterion is income per capita; countries with high gross domestic product (GDP) per capita would thus be described as developed countries.

Environmental science

Environmental science is a multidisciplinary academic field that integrates physical, biological and information sciences to the study of the environment, and the solution of environmental problems.

Chemistry

the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

Ecological footprint
