BRAINCAKEConservation
Conservation is the protection and careful management of species, habitats and ecosystems so that biodiversity is maintained for the future. It is not the same as preservation: conservation often involves active work, such as managing habitats or breeding animals, rather than simply leaving an area alone.
Species need conserving because human activity is driving them towards extinction. The biggest single threat is habitat loss, for example forest cleared for farming or building. Other threats include overexploitation (overfishing, hunting and poaching), pollution, climate change and invasive non-native species.
