We can make environment clean and less polluted by employing effective measures. We should therefore, attend to the following point in this respect:
1. Renewable resources should be used at that rate in which they are being replenished.
2. Silviculture should be started to replenish forests for producing raw materials and increasing the area under forests.
3. Large scale killing of animals should be banned, e.g. if we kill more snakes for their skin, the population of rats and mice will increase and that will cause heavy damage to crops.
4. Natural habitat of animals should be preserved.
5. Monitoring the number of wild animals in sanctuaries be done.
6. Poaching should be banned.
7. Concerned officials should make surveys.
8. Uncontrolled felling of trees should be curbed.
