A .
The Ramsar Convention, whose official name is the "Convention on Wetlands of International Importance especially as Waterfowl Habitat", was primarily a treaty to conserve the nature of wetlands in order to provide living places for waterfowls.
Through conferences of countries joining the convention, it comes to conserve wetlands as living places not only for waterfowls but also for fish. The idea of the convention has recently changed into conserving wetlands as living places for all wildlife which live there, not being limited to a certain species of bird or fish.
Its idea is now developing to consider water and to use it properly as a source of life for all living things in the wetlands.
