5. How can people’s participation be effective in conserving forests and wildlife? [HOTS]
Answer: It is also our duty to preserve wildlife. We should avoid reckless hunting of wild animals, indiscriminate felling of trees and clearing of forests to protect our national wealth, i.e. wildlife. Common people have a large role to play in the conservation of forests and wildlife. We can participate in environmental movements and pressurize the government, both at the state and Central level to bring stricter laws to conserve our forests and minimise the industrial impacts on the environment. We can also refuse to use products that intensively harm the forest and wildlife during their production and when they are disposed of. Afforestation should become people’s movement and more trees should be planted.
