Environmental law is a very complex area of law, with its intertwining groups of treaties, regulations, conventions and statutes. In a broad sense, environmental law strives to regulate how mankind interacts with the world as a whole. The crux of the issue for an environmental lawyer is an attempt at lessening the impact of the human activity on the planet by attempting to control pollution and thus conserve the Earth for future generations. Environmental law is popular with those students who have undergraduate backgrounds in public and environmental affairs and there are plenty of resource books available for those wishing to pursue a degree in this area in the future. Lawyers who are currently practicing will find a wealth of new knowledge in the subject of environmental affairs that will be applicable to cases currently on their caseload, such as those involving land management or the misuse of government lands or waterways.
