Step-by-step solution
The 'Evil Quartet' describes the four major causes of biodiversity loss. Habitat loss and fragmentation is the most important cause driving animals and plants to extinction. Mammals and birds requiring large territories are badly affected, leading to population declines. Over-exploitation by humans has led to the extinction of species like Steller's sea cow and the Passenger pigeon. Alien species invasions, such as the introduction of the Nile perch into Lake Victoria, led to the extinction of more than 200 species
