Research says biodiversity helps protect nature against human impacts http://apocadocs.com/s.pl?1360179963
Their research, published today as the cover story in Nature, suggests farmers and resource managers should not rely on seemingly stable but vulnerable single-crop monocultures. Instead they should encourage more kinds of plants in fields and woods as a buffer against sudden ecosystem disturbance. Based on a 10-year study, their paper also lends scientific weight to esthetic and moral arguments for maintaining species biodiversity....
McCann, who studies food webs and ecosystem stability, said many ecosystems are at a "tipping point," including grasslands that may easily become either woodlands or deserts. "They're a really productive ecosystem that produces year in and year out and seems stable and then suddenly a major perturbation happens, and all of that biodiversity that was lost earlier is important now," said McCann.

Clearly, Monsanto needs to engineer more biodiversity into its corn and soybean genomes.
