Question
What are the summit arranged by all countries to conserve biodiversity?

Answer

→ Biodiversity knows no political boundaries and its conservation is therefore a collective responsibility of all nations.
→ The historic Convention on Biological Diversity ('The Earth Summit') held in Rio de Janeiro (Brazil) in 1992, called upon all nations to take appropriate measures for conservation of biodiversity and sustainable utilization of its benefits.
→ In a follow-up, the World Summit on Sustainable Development held in 2002 in Johannesburg, South Africa, 190 countries pledged their commitment to achieve by 2010, a significant reduction in the current rate of biodiversity loss at global, regional and local levels.
