Environmental law in India has developed partly in response to demands by environmental groups and partly as a result of international conventions. The laws to protect bio diversity were a direct outcome of the International Convention on Biodiversity.
After the 1992 United Nations Conference on Environment and Development in Rio de Janeiro, a number of laws were changed or new rules drafted to conform to international agreements. Local environment groups played an important role in bringing in the Coastal
Regulation Zone Rules, an outcome of growing awareness of the impact of development along the coasts of marine resources.
