We turn to environmental science to give us answers to essential questions about the physical world we live in. Environmental science has existed in one form or another for centuries, but its popularity drastically increased in the middle of the 20th century. As technology increased in the last century, societies began to realize their lifestyles have a serious impact on the environment.

Environmental scientists study a wide range of issues, such as air pollution, sustainability, soil contamination, waste management, and climate change. These fields are so varied that it is not uncommon for an environmental scientist to work closely on a project with a trained professional from a different field. Anthropologists, biologists, chemists, and sociologists often work in tandem with environmental scientists.

Generally, environmental science involves issues that are pressing to today's population. Global warming, endangered species, contamination, and erosion are among the topics most frequently discussed by members of this field. Scientists work diligently to understand the impact modern society has on the environment, as well as offer solutions to current problems.

As technology becomes more advanced and the human population continues to require the use of precious natural resources, environmental science will be a necessity in order to keep the impact of modern society in check. World governments often work in conjunction with scientists to ensure state industries are in compliance with environmental regulations. Many feel government involvement sets a good example that is important for reaching out to the general population and teaching them how to better care for the world around them.
