Causes of recent declines in biodiversity The major causes of biodiversity decline are land use changes‚ pollution‚ changes in atmospheric CO2 concentrations‚ changes in the nitrogen cycle and acid rain‚ climate alterations‚ and the introduction of exotic species‚ all coincident to human population growth. For rainforests‚ the primary factor is land conversion. Climate will probably change least in tropical regions‚ and nitrogen problems are not as important because growth in rainforests is usually
