Entry-level environmental science jobs include working in biology, geology, chemistry, education, public relations, public policy, or consulting. Your specific duties differ depending on whether you have a research job or a position in analysis or public relations, which typically requires more extensive writing and a broader knowledge of public policy, ecological law, and environmental regulations. In a research position, your responsibilities include handling sample and data collection, performing land surveys, conducting assessments of wildlife habitat and wetlands, testing and analyzing samples, and helping with studies that recommend further research or policy changes. Environmental science researchers may work at an academic or research institution, while other environmental science professionals may work for a non-profit or in private industry or government.
