ABSTRACT
The scope of environmental science includes law and management. Environmental science, which is closely related to Ecology, is concerned with global environmental change which can occur in both aquatic and terrestrial ecosystems. This change can occur via both natural and anthropogenic (man-made) means. Many of these changes are from nonpoint and point pollution. Two major concerns of contemporary environmentalists are global climate change and pollution. Whereas the former centers around global warming, the latter involves detecting, analyzing and reducing air, ground, noise, thermal and water pollutions. Other concerns are population growth and species extinction. To this end, environmentalists often use ecological methods. Thus, environmental science is often more encompassing than ecology, which in its pure form is a branch of Biology. In popular usage, ecology has been mistakenly equated with environmental activism.
