Deforestation is the removal of a forest or stand of trees from land and using that land for other purposes.
- Causes of Deforestation are man-made as well as natural.
- Deforestation is causing immense damage in the form of increase in temperature, droughts, floods, desertification, loss of habitat of animals and plants, etc.
- We must conserve forests as they provide home to nearly half of all species found on earth. Forests preserve biodiversity and reduce air pollution by filtering the air.
- The forests can be conserved by controlling forests fires and planting more trees. We should spray chemicals & antibiotics to protect forests from pests and diseases.
- Wildlife conservation is important as it protects biodiversity, promotes tourism and provides jobs to lacs of people etc.
- We can conserve wildlife by putting an end to unauthorized cutting of forest trees, moving towards a plant-based diet, by establishing more number of national parks and sanctuaries etc.
- Each plant and animal has its own role to play in the ecosystem. All the species of plants and animals form part of food chains and food webs. If we go on cutting trees and and do not take necessary steps to conserve forests and wildlife, the day is not far when human race would also be in great danger.
