The branches of environmental science are ecology, atmospheric science, environmental chemistry, environmental engineering and geoscience. Environmental science is the study of the environment with a focus on providing solutions to environmental problems.
Environmental scientists study the Earth and work on alternative energy, pollution control and management of natural resources. Green technology helps produce clean energy, reduces wasteful practices, and helps restore the environment. Solar and wind power are newer forms of energy. Environmental science incorporates subjects such as physics, chemistry, zoology, mineralogy, oceanology, limnology, soil science, geology, geography and geodesy. Ecology includes conservation, which is a field that seeks to protect organisms from extinction caused by the depletion of natural resources.
