Question: What is the threat to vegetation and wildlife? What is the need to conserve them? How can we do this?

Answer: Forests and wildlife are an important resource. Climate change and human interference in the animal kingdom can cause loss of natural habitat for plants and animals. Certain species have become endangered and many have become extinct now. Poaching incidents contribute to their extinction. Plants and animals are an important part of the ecosystem. Plants provide food, oxygen and shelter to humans and animals. Animals provide us important products such as milk, meat, honey, etc. There exists a balance in the environment if we do not disturb the natural number of species living on the earth. A single extinction can affect the ecosystem badly. So animals and plants obviously need to be conserved. The government has introduced national parks, wildlife sanctuaries and biosphere reserves for this purpose. Poaching should be severely dealt with. Indiscriminate killings need to be discouraged. Social awareness must be created about importance of trees, social forestry. Students should be involved in vanamahotsavas at regional and community levels.
