BRAINCAKEProblems with Conservation
Conservation aims to protect species and habitats, but it often faces practical, economic and ethical problems.
Conflict with human needs: protected land cannot be used for farming, housing, logging or mining. For people in poorer countries a reserve can mean lost income and food, and animals such as elephants or big cats may raid crops or kill livestock. Conservation works best when local people benefit, for example through ecotourism jobs or sustainable harvesting.
Cost and enforcement: reserves need money for staff, fences and anti-poaching patrols, and poaching continues where rewards are high, such as for rhino horn and ivory.
