Mention the major causes for loss of biodiversity?
The four major causes that are responsible for loss of biodiversity are:- i) Habitat loss and fragmentation of crops or conversion into grassland for raising beef cattle. Total loss of habitat deprives many plants and animals of their home and they face extinction. Similarly, when a large Habra becomes fragmented, then the animals requiring large territory and also those with migratory habits are getting affected adversely. ii) Overexploitation:- when nature is over-exploited by man for natural resources, many species become extinct. iii) Invasion of alien species:- The alien species become invasive and compete with native species and cause the extinction of indigenous species. iv) Co-extinction:- Co-extinction is a phenomenon in which when a species becomes extinct, the plant and animal species associated with it in an obligatory manner become extinct
