A study titled “Hotspots of human impact on threatened
terrestrial vertebrates”, published in the journal PLOS Biology, has reported human impacts on species occur
across 84% of the earth’s surface.
The study has mapped distribution of human
activities in areas occupied by known 5,457 terrestrial birds, mammals, and
amphibians. The human activities taken
into account are hunting, harvesting, and the conversion of natural habitats
for agriculture, urbanisation, and other industrial activity.
The study identified global hotspots of impacted
species- regions were species are most impacted by anthropogenic activities. Malaysia
has ranked first among the countries with the highest number of impacted
species (125), followed by Brunei and Singapore. India has ranked 16th (35
threatened species affected on average). Forests in Western Ghats, Himalaya and
north-east are particularly threatened.
The study has also identified ‘coolspots’ that
act as refuges from threats. The study has reported that the tundra and boreal
forest are the only biomes where more species are unimpacted than impacted on
