Q.9. Write a note on the significance of bio-diversity and critically evaluate difference between the in-situ and ex-situ conservations. (20Marks)

 Ans. Biodiversity and its maintenance are very important for sustaining life on the Earth. A few of the reasons explaining the significance of biodiversity is as follows:

1. Ecological Stability: - Every species has a specific role in an ecosystem. They capture and store energy and also produce and decompose organic matter. The ecosystem supports the services without which humans cannot survive. A diverse ecosystem is more productive and can withstand environment stress.

 

2. Economic Importance: - Biodiversity is a reservoir of resources for the manufacture of food, cosmetic products and pharmaceuticals. Crops livestock, fishery and forests are a rich source of food. Wild plants such as Cinchona and Foxglove plants are used for medicinal purposes. Wood, fibres, perfumes, lubricants, rubbers, resins, poison and cork are all derived from different plant species. The national parks and sanctuaries are a source of tourism. They are a source of beauty and joy for many people.

 

3. Ethical Importance: - All the species have a right to exist. Humans should not cause their voluntary extinction. Biodiversity preserves different cultures and spiritual heritage. Therefore, it is very important to conserve bio-diversity.

 

 

IN-SITU CONSERVATION

In-situ conversation is a special method of conserving wildlife species in their own natural habitats. The essence of the in-situ conservation techniques is hidden in their stress on the onsite protection of biodiversity. The belief that biodiversity flourishes while growing in the midst of its natural home, where each of the endangered species can adapt and evolve with the changing environment. in situ conservationists believe in the preservation, monitoring and management of natural areas that are home to endangered species. The creation of national parks, biosphere reserves and sanctuaries serve as ways of protecting species as well as ensuring their dynamic natural growth.

 

EX-SITU CONSERVATION

Ex-situ conservation proposes the protection of species outside their natural habitat. Under this form of conservation, artificial habitats that mimic the natural environment of endangered species are created. This enables the protection of endangered and almost extinct species by restricting their mobility and reducing the threat of potential predators. These methods also encourage captive breeding to boost the member counts of species and prevent extinction. In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. It includes zoological parks, botanical gardens and seed banks.

 

 

DIFFERENCE BETWEEN IN-SITU AND EX-SITU CONSERVATION

The main difference between in situ and ex situ conservation is in terms of the definition and meaning of each term. While the former stands for the ways of conserving endangered species of plants and animals within their natural habitats, the latter refers to the ways of conserving biodiversity offsite, i.e. outside their natural habitat.

 

The second seminal difference between the two is kind of environment and habitats created by each. While in situ conservation, we create national parks and sanctuaries to protect wildlife in their natural environment; in ex situ conservation, we uses artificially created environment that resemble the natural living space of species.

 

All species are allowed to adapt and multiple in in-situ conservatory methodology. Under ex-situ conservation, captive breeding helps boosts the numbers of some species. However, natural adaptability is absent in the later.

 

 

CONCLUSION

In-situ conservation units are biosphere, reserve national parks and sanctuaries, while ex-situ conservational units include zoological parks, aquarium, and botanical gardens. Both, in-situ and ex-situ conservation are methods of natural conservation and protecting endangered flora and fauna. Each of these methodologies has its own set of benefits and pitfalls. They are significantly different from each-other in terms of their proposed methods of protecting biodiversity.
