Of the four major causes for the loss of biodiversity (Alien species invasion, habitat loss and fragmentation, over-exploitation and co-extinctions which according to you is the major cause for the loss of biodiversity? Give reasons in support.

Habitat loss and fragmentation is the major cause for this problem, due the following facts:

a) Large areas broken into fragments results in reduction of the core area and increase in edge areas.

b) This causes depletion of the natural resources leading to the scarcity of food for the living wild life.

c) The tropical rain forest reduced to 6% from 14% of the total earth surface.

d) The increasing rate of urbanisation and increase in the deforestation is the major cause of habitat loss which ultimately leads to the biodiversity loss.
