The historic Convention on Biological Diversity, ‘The Earth Summit’ was held in Rio de Janeiro in the year
1992
1986
2002
1985
The Correct Option is A
Solution and Explanation
The Convention on Biological Diversity (CBD) was adopted during the United Nations Conference on Environment and Development (UNCED), which took place in Rio de Janeiro, Brazil, from June 3 to June 14, 1992. The summit is commonly known as the Earth Summit and marked a significant milestone in global efforts to address biodiversity conservation and sustainable development.
Therefore, The correct option is (A): 1992

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Loss of Biodiversity
The reduction in the number, genetic variability, and the variety of species and the biological community of a place is known as the Loss of Biodiversity. By humans, due to the colonization of the tropical Pacific Island, there has been a deprivation of more than 2000 species. Present data evaluates that around 15,500 species are endangered. Presently the loss of biodiversity is evaluated at - 23% of all mammal species, 12% of all bird species, 32% of all amphibian species, and 31% of gymnosperm species on the planet are facing the threat or warning of extinction.
Loss of Biodiversity: Causes
- Loss of Habitat and Fragmentation
- Over Exploitation of Natural Resources
- Alien Species Invasion
- Co-Extinction
