Habitat Destruction
Nearly half of the planet’s plant and animal species live in Rainforests. Less than 2.5 billion acres of Tropical Forest have remained out of four billion acres on the Earth within a few hundred years.
Conservation of Wildlife
Conservation of species in their natural habitats- in areas where they occur under normal conditions is called in-situ conservation.
This type of conservation strategy protects the entire area. Such an area is protected and maintained to conserve all the known or unknown species inhabiting it.
In this type of conservation, species are not isolated or provided with health care, food, or mating facilities. Only factors detrimental to species’ existence and development are eliminated in this conservation strategy. Human interference, such as hunting, cutting down trees, collecting firewood, etc., is completely banned in such areas.
