Answer:
Brazil: Degradation of environment due to illegal smuggling of wild animals, slash-and-burn agriculture (roca), deforestation (about 5831 sq km of forest land was degraded in 2016) and pollution. Many endemic species are on the verge of extinction.
India: Many species of wildlife are on the verge of extinction because of poaching, pollution and rapid deforestation; for example, cheetahs have disappeared, and the numbers of tigers and elephants are decreasing. India has set up national parks, wildlife sanctuaries, bird sanctuaries and biosphere reserves for protection of forests and wildlife.
