Environmental Concerns

This is a type of photochemical air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere.

• Pollution

• Chlorofluorocarbon

• Smog

• Greenhouse Effect

This is a warming of the planet due to carbon dioxide and hear retention.

• Pollution

• Global Warming

• Smog

• Greenhouse Effect

This is the scale used to describe how acidic or basic a solution is. This affects the enzymes within living systems.

• Biogeochemical Cycle

• pH

• Smog

• Global Warming

This is the contamination of an environment beyond natural correction.

• Endangered Species

• Extinction

• Pollution

• Habitat Loss

An organism facing extinction through destruction of habitat; the process may threaten the survival, abundance, or evolutionary development of the species.

• Threatened Species

• Endangered Species

• Extinction

• Habitat Loss

This is the ceasing of the existence of any particular species.

• Threatened species

• Endangered species

• Extinction

• Habitat Loss

A pathway by which a chemical element or molecule moves through both biotic and abiotic compartments of an ecosystem.

• Biogeochemical Cycle

• Chlorofluorocarbon

• Pollution

• pH

A process of land use change in which plants and animals which previously used the site are displaced or destroyed. Generally this results in a reduction in biodiversity.

• Global warming

• Extinction

• Threatened species

• Habitat Loss

A theory of overall increase in world near-surface air and ocean temperatures which may be caused by additional heat being trapped by greenhouse gases.

• Biogeochemical cycle

• Global warming

• Greenhouse effect

• Smog

Any living organism which is "in danger of extinction throughout all or a significant portion of its range".

• Extinction

• Threatened species

• Endangered species

• Habitat loss
