Climate change, pollution and various environment alterations across the globe are changing the identity of grasslands, according to a new study by Proceedings of the National Academy of Sciences (PNAS) journal. Grasslands occupy more than 40 per cent of all the ice free land in the world. Grasslands also provide food and shelter for various other species including Zebras and Giraffes. Thirty per cent of the world’s carbon is stored in these Grasslands, which makes them crucial in combating climate change. But, the Grassland ecology is shifting due to human activities, says the new study. Even though the grasslands are resilient towards global change for around 10 years, it is vulnerable due to the fast pace of global change.
