In addition to sunlight, air, soil, water,  the eanh has got the right pressure and temperature  that enables  life to exist, evolve,  and diversify. Actually  there exists a very delicate balance in nature between the earth's environment and the living organisms. If  this balance is disturbed then the life that exists (day  is likely to be affected or even destroyed. Flash floods.andsoi1  erasion are same of the adverse effects  of this imbalance. Therefore, we must understand that how living and non-living things exist in harmony with nature and what aie  the processes that maintain this balance.
