And, although many concerns have been expressed about the potential for unexpected consequences, the unexpected effects that have been observed so far have been benign.

One of the really remarkably beneficial aspects of genetic engineering is that much of the previous methodology for controlling pests and so forth is through chemicals that affect a very broad spectrum of insects, for example, or fungicides that control fungi.

The signs of climate change are visible across the nation, from the drought-stricken fields of Central California to the flooded streets of Michigan. Extreme weather is turning people's lives upside down and costing communities millions of dollars in damaged infrastructure and added health care costs.
