Question

Find the odd one out: IPCC, UNEP, IUCN, BNHS.

Answer 1

Hint: There are different associations that work for different causes on this planet and some are national and some are international. The flora and fauna need to be conserved and to preserve the biodiversity of this land these conventions are made and run by governments to promote awareness along with their conservation.

Complete answer:
> IPCC- The full form for it is as under- Intergovernmental panel on climate change.
The main objective of the IPCC is to report to governments at all levels with scientific information that they can utilize while developing climate policies.

> UNEP- It stands for the United Nations Environment Programme and it is responsible for assisting developing countries in implementing environmentally sound policies and practices along with coordinating the UN's environmental activities.

> IUCN- The International Union for Conservation of Nature is the full form of IUCN. The International Union for Conservation of Nature is an international organization that works in the field of nature conservation and sustainable use of natural resources. It gathers data and analyses it, researches it, performs field projects, etc.

> BNHS- The Bombay Natural History Society was founded on 15 September 1883. It is considered as one of the largest non-governmental organizations and is situated in India. They are engaged in conservation and biodiversity research. It supports research efforts receiving grants and then it also publishes the Journal of the Bombay Natural History Society.

As we can see from the above definitions that all the others are International organizations while the Bombay National History Society is a non-governmental organization. Also, IPCC, UNEP, IUCN are concerned with the environment and Climate and only BNHS is concerned with biodiversity.
The odd one out is BNHS that is Bombay Natural History Society.

Note: IN 1956, IUCN changed its name to the International Union for Conservation of Nature and Natural Resources (IUCN) and was also known as the World Conservation Union (IUCN) from 1990 to 2008. It is one of the world's oldest global environmental organizations. It contains a red list.
