A biologist called Jared Diamond coined the phrase ‘the evil quartet’ to describe the four main human-induced causes of extinction: habitat degradation and fragmentation, introduction of exotic species and over harvesting.
Habitat degradation and fragmentation include wetland destruction, river pollution, deforestation of woodlands and rainforest, and even just the isolation of pockets of forest as roads are built through them. These changes affect species in a number of ways. They are associated with reductions in population sizes and increased isolation of populations as well as, potentially, novel selective pressures.
