Answer 1

The work of Environmental Science describes the environment,interprets the impact of human actions (anthropogenic effects) on terrestrial and aquatic ecosystems,and develops strategies for restoring ecosystems.In addition,environmental scientists help planners develop and construct buildings,transportation corridors,and utilities that protect water resources and reflect efficient and beneficial land use.[2].Due to the interdisciplinary nature of environmental science,teams of professionals commonly work together to conduct environmental research or to produce Environmental Impact Statements.Other professional organizations engender work in environmental science and aid in communication among the diverse sciences.
Since most environmental issues deal with human activities,study of economics,law and social sciences are often applied in conjunction with environmental science.
Environmental science encompasses issues such as climate change,conservation,biodiversity,water quality,groundwater contamination ,soil contamination,use of natural resources,waste management,sustainable development,disaster reduction,air pollution,and noise pollution.
While the environment has been studied for at least as long as there has been science,the recent interest in putting the pieces of understanding together to study environmental systems has come alive as a substantive,active field of scientific investigation starting in the 1960s and 1970s.This has been driven by the need for a large multi-disciplined team to analyze complex environmental problems,the arrival of substantive environmental laws requiring specific environmental protocols of investigation,and growing public awareness of a need for action in addressing environmental problems.
