Conservation

Conservation, the preservation or efficient use of resources, can include nature conservation—the protection and management of the environment and natural resources—and its subcategory wetland conservation—protecting and preserving areas where water exists at or near the Earth's surface, such as swamps, marshes and bogs.

Wildlife conservation is the practice of protecting wild species and their habitats in order to prevent species from going extinct .

Water conservation is the aim to sustainably manage the natural resource of fresh water, protect the hydrosphere, and meet current and future human demand.

The first organized roots of the modern conservation movement trace back to 1662 in England with John Evelyn's forestry paper Sylva, though the large-scale public movement began in the mid-to-late 19th century in the United States.
