Answer the following.
How the biodiversity can be conserved?
उत्तर
Two approaches followed for the conservation of biodiversity are:
- In-situ conservation: In order to conserve biodiversity better, biodiversity hotspots all around the world have been identified and protected. In India, biosphere reserves, wildlife sanctuaries, and national parks have been developed for this purpose.
- Ex-situ conservation: The threatened species of plants and animals are taken out of their habitats and are kept in special settings such as zoological parks, botanical gardens, and wildlife parks. Nowadays, the gametes of endangered species can be preserved by methods such as cryopreservation. They can also be fertilized in-vitro followed by propagation through tissue culture methods. Similarly, seeds can be preserved in seed banks.
