Biodiversity is the vital factor for ecosystems (deserts, rainforests and coral reef )
It increases ecosystem productivity for example a vast variety of crops.
Comprehensive species diversity provides natural sustainability for all life forms. Therefore the diversity is preserved in wildlife.
The reasons of species extinction are due to over exploitation of resources by human, climate change, fragmented habitats, habitat destruction and ocean acidification.</li></ul>If this issue isn’t regarded by societies and governments, it will take a long time for nature to recover.<br />
