NCERT gives India biosphere reserves, national parks and wildlife sanctuaries.
- How many protected areas of these three kinds are there in all?
- What per cent of them are wildlife sanctuaries? Give one decimal.
- How many national parks are there for each biosphere reserve? Give one decimal.
Need a reminder? The key ideaShow
The Earth Summit was held at Rio de Janeiro in 1992. At Johannesburg in 2002, 190 countries pledged to reduce the rate of biodiversity loss significantly by 2010. NCERT gives India 14 biosphere reserves, 90 national parks and 448 wildlife sanctuaries. These summits are not in the NEET syllabus.
