Answer 1

Biodiversity knows no political boundaries and its conservation is therefore a collective responsibility of all the Nations. The historic convention on Biological diversity takes place from time to time. There have been many summits in which discussion of conservation of biodiversity and sustainable utilisation of benefits of biodiversity take place.

Complete step by step answer:
1.Two summits are held on biodiversity which are known as The Earth Summit and The World Summit.
2.A Summit in which the Nations of the world were called up to take appropriate measures for conservation of biodiversity and the sustainable utilisation of his benefits. It was known as the Earth summit and held in Rio de Janeiro in 1992 .
3.After the Earth Summit the second Summit held on this topic was The World Summit on sustainable development held in 2002 in Johannesburg South Africa , 190 countries pledged about a significant reduction in the loss of biodiversity taking place at global and in their own country.
4.There are many reasons to conserve our biodiversity some of them are the benefits you drive from biodiversity such as food , firewood or fibre. The benefits of dyes , perfumes we get from nature. The medical important products such as drugs which are derived from plants. All of these are narrowly utilitarian arguments for conserving biodiversity.
5.The broadly utilitarian benefits of biodiversity are oxygen we get from the atmosphere from the process of photosynthesis. Pollination without which plant cannot give us fruits of seed .

Hence the correct answer is option(A)

Note: There are also the ethical arguments for conserving biodiversity. We should take care of biodiversity as a duty to serve our future .
