By becoming selfish, man is shooting himself in the foot in the pursuit of progress. Intoxicated by industrialization and progress, it is disturbing the balance of the environment. The population is increasing rapidly. People need houses etc. to live. Forests are being cut down to get land.
Tree plantation is being done but still forest erosion has increased significantly. The farmer is doing agriculture by clearing the forests. If there are no forests then where will the animals and birds live? Their home is the forest. Trees and forests are being cut to obtain many types of valuable wood.
The environment is being harmed so much that mankind is continuously falling prey to natural disasters. It is also the responsibility of man to keep the water of all reservoirs and rivers clean and protected.
Today the whole world is worried about the environment. If we all do not become alert now, then nature will take its fierce form and everything will come to an end.
