"Expanding Farms Harm Nature On 58 Pct Of World's Land: Study"

"An expansion of farmland has damaged nature beyond a "safe" limit on 58 percent of the world's land surface, threatening natural services such as crop pollination by insects, scientists said on Thursday.

Grasslands, such as in United States, Argentina, South Africa or Central Asia, are among natural systems most affected by declines in animals and plants caused by human activities, they wrote in the journal Science.

Northern pine forests and tundra are least affected, they said."
