Environmental scientists and specialists use their knowledge of the natural sciences to protect the environment and human health. They develop strategies to clean up polluted areas, advise policymakers, and work with industry to reduce waste or hazards. Environmental scientists gather and analyze data to shed light on important questions, including how to prevent or handle environmental problems… then use their findings to inform the public, private industry, government officials, and others about environmental hazards. Day-to-day tasks can vary a lot among these specialists: Climate change analysts study the effects of changing climatic conditions on ecosystems. Environmental health specialists study how environmental factors affect community and individual human health. Environmental restoration planners determine how to clean up polluted sites and assess costs. And industrial ecologists work with industry to develop sustainable and efficient practices that limit adverse impacts on the environment. While environmental scientists generally work full time in an office or laboratory, some head to the field to check out environmental conditions and gather samples of air, soil, water, or food. Most entry-level positions require a bachelor’s degree in a natural science or related field, but a master’s degree is often needed for advancement. Whether teaching or practicing methods to keep our air, water, and land clean and free of health risks, the work of environmental scientists hits home.
