Number of wild life is continuously decreasing. What is the main reason of this : -The main causes of loss of biodiversity are habitat loss and fragmentation, over-exploitation, alien species invasions and co-extinctions (the 'evil quartet').
Habitat loss and fragmentation is the most important cause. When forests are cleared for agriculture, industry and settlements, or wetlands are drained, the animals and plants living there lose their homes, food and breeding grounds.
Cutting down forests is one form of habitat destruction; hunting and predation affect fewer species.
So the main reason for the decrease in wildlife is destruction of habitat.
