Reasons for the decline in biodiversity.

Reasons for the decline in biodiversity : 1. The rate at which population explosion is taking place in our country is the main reason behind decline in biodiversity. 2. Single crop method of agriculture has endangered the biodiversity among the plant kingdom. 3. Due to the entry of hybrid and imported varieties of breeds, local breeds are replaced. 4. Cutting down of the trees. 5. Hunting of the animals. 6. Clearing off the land by cutting vegetation and utilizing it for human habitation. 7. Building dams, roads and factories. 8. Mining operations 9. Unbridled consumption of natural resources. 10. Destruction of habitats rich in biodiversitx. 11. Pollution in the environment. 12. Rising temperatures of the earth ( gloaal warming ) and climatic changes. Protection of rare species : 1. It is very important to protect rare plant and animal species. 2. Laws have been enacted to protect animals and plants of endangered species. 3. Creating National and Wildlife Sanctuaries. 4. Formation of Reserved Biodiversity Zones. 5. Specific and rare species to be nurtured through special projects. 6. Zoological and botanical gardens to be established for nurturing rare species of animals and plants respectively. 7. Compilation and documentation of traditional knowledge. Conservation of biodiversity throgh biotechnology : Local species have characteristics such as resistance to disease, survival in adverse conditions conditions and shorter life cycles. These species and the new varieties can be crossed with each other and the desirable characteristics can be preserved. Seed banks and gene banks can be helpful for such purpose. Thus biotechnology helps in conserving biodiversity. Reserved biodiversity zones : These are the areas in which wildlife is protected, but local people are allowed to carry out their daily activities.
