Environmental science is one of the major unifying themes of biology, as life arises and evolves within the context of a particular environment. It is the interaction of the biotic components (such as food and predators) and abiotic components (such as oxygen, water, sunlight, and temperature) which drives evolution, determining which species will thrive and which will fade away.

In the coming years, environmental issues, such as energy and water resource use, pollution, global warming, and habitat destruction will have major effects upon both humans and non-humans. Previous natural extinction events, such as asteroid collisions and volcanic eruptions have caused the destruction of 90% or more of earth's species. Presently, we are in the midst of a man-made extinction event, with similarly dire consquences.

It is essential that students, as citizens and future leaders, will understand environmental issues and be able to make informed wise decisions.

To the best of human knowledge, Earth is the only place where life exists. It is our responsibility to take care of it.
