Question

important of preservation and conservation of biodivesity??

Answer 1

Biodiversity is the life support system of our planet- we depend on it for the air we breathe, the food we eat, and the water we drink. Wetlands filter pollutants from water, trees and plants reduce global warming by absorbing carbon, and bacteria and fungi break down organic material and fertilize the soil. It has been empirically shown that native species richness is linked to the health of ecosystems, as is the quality of life for humans.

Answer 2

Think of a world where there is only man............
How bad it will be? we need trees, birds, butterflies, paddy fields, forests, insects, fishes, bacteria, fungi ........all are needed, for life to pertain on EARTH. Each has its own role- plants fixes solar energy to carbohydrates, remove CO2 from atmosphere, Insects pollinate flowers
Frogs prevent swarming of insects, snake prevent frogs and rodents from swarming up, carnivores kill herbivore animals to prevent excessive grazing, bacteria and fungi decompose dead animals and plants and bring back them to soil. This will remain as a cycle if there is only bio-diversity.
Nb:there is no one to control human beings, as they are destroying the diversity what nature has created.
