This has led to efforts towards clean air , water protection, noise abatement, waste management , pollution control, re-forestation, etc. All this require services, thereby creating job opportunities for those trained in environment science. This discipline is composite for both natural and social sciences. At its roots lie natural history and the science of ecology. Resource management ant resource technology are also significant features.
Astute stewardship is required to make our finite resources last as long as possible.
Demography is also therefore linked to this study. The job involves utilising the knowledge of various principles and concepts of science and engineering discipline to protect the environment, conduct research studies to develop methods to control environmental pollution. As it is mandatory for industries to obtain environmental clearances ,environmental scientist play an important role in industry. Most industrial organisations appoint them in their environmental research and development section to manage and plan for environment protection. Besides, many industries employ environmental engineers to control, eliminate and prevent environmental hazards.
