Short Answer TypeMany plant and animal species are on the verge of their extinction because of loss of forest land by indiscriminate use by the humans. As a biology student what method would you suggest along with its advantages that can protect such threatened species from getting extinct?
As a biology student, I would suggest the following methods to protect the threatened species from becoming extinct:
i. 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. This protects the organism, help maintain their number and prevent them from becoming extinct.
ii. Using the method like cryopreservation of the gametes of endangered species and their fertilization by the method of in-vitro fertilization. The use of tissue culture for propagation of the organism and the use of seed banks in case of plants. These methods allow us to preserve the genes of the endangered species and can be used to increase the number of endangered species by keeping the gamete or seeds viable and fertile for a longer period of time and using it when required.
iii We can lower the rate of deforestation avoiding indiscriminate use of forests and thus save the habitat of the species and protect them from extinction.
