Agricultural Soils Exhausted

"By the 2080's global food production on land could be at crisis point. In the cooler, wealthier parts of the world, where intensive agriculture has been adding too much fertilizer for a century, the soils would be exhausted and lifeless. Key harvests would fail. In the warmer, poorer parts of the world, global warming may bring higher temperatures, changes in the monsoon, storms and droughts that doom farming to failure. Across the world, millions of tonnes of lost topsoil could enter the rivers and bring flooding in the towns and cities downstream... If the current rate of pesticide use, habitat removal and the spread of disease in pollinators like bees continues, the loss of insect species would come to affect three quarters of our food crops by the 2080s.Nut, fruit, vegetable and oilseed harvests could fail if unable to rely on the diligent work insects for their pollination."
