Environmental researchers propose radical 'human-centric' map of the world

fts in ecosystems," said Ramankutty. "The human influence on the planet today is almost on the same scale. Nearly 30 to 40% of the world's land surface today is used just for growing food and grazing animals to serve the human population."

The researchers argue human land-use practices have fundamentally altered the planet. "Our analysis was quite surprising," said Ramankutty. "Only about 20% of the world's ice-free land-surface is pristine. The rest has some kind of anthropogenic influence, so if you're studying a pristine landscape, you're really only studying about 20% of the world."

"If you want to think about going into a sustainable future and restoring ecosystems, we have to accept that humans are here to stay. Humans are part of the package, and any restoration has to include human activities in it."
