write notes about the wild life on the verge of extinction
Answers
Answer:
An endangered species is a species which has been categorized as very likely to become extinct in the near future. Endangered (EN), as categorized by the International Union for Conservation of Nature (IUCN) Red List, is the second most severe conservation status for wild populations in the IUCN's schema after Critically Endangered (CR).
Answer:
India has about 8 percent of the world’s biodiversity on 2 percent of the earth’s surface, making it one of the 12 mega-diversity countries in the world. Of about 1.75 million species globally identified, around 1,26,188 species have been reported so far from India. The species recorded include flowering plants (angiosperms), mammals, fish, birds, reptiles and amphibians, constituting about 17.3 percent of the total, whereas fungi and insects make up nearly 60 percent of India’s bio-wealth. This diversity can be attributed to the great variety of natural ecosystems due to the varied physical and climatic features found in India.
India ranks tenth in the world both in respect of richness of flowering plants (17,500 spp.) and mammals (350 spp.) and fourth in Asia in plant diversity. India is also a centre of crop diversity, a homeland of as many as 167 species of crops and 320 species of wild crop relatives.
The country has 10 different bio geographic zones and 26 biotic provinces gifted with unique and rare species of flora and fauna
Explanation:
Habitat destruction is the main cause for wildlife extinction in India. The rapid deterioration of the environment due to human interference is aiding the disappearance of wildlife from the biosphere. According to IUCN, habitat loss and degradation have affected about 89 percent of all threatened birds, 83 percent of mammals and 91 percent of all threatened plants globally. Habitat loss is due to deforestation for extended cultivation, construction of dams, mining operations and road laying. When the natural habitat of animals is destroyed, it leads to a decline in their primary food supply and breeding and nesting grounds. Hence their numbers get drastically reduced. In the case of plants, if their natural habitat is destroyed and the species that controls the pests that attack them are lost, then their survival is at risk.
