Nina Fedoroff — American Scientist

Nina Vsevolod Fedoroff is an American molecular biologist known for her research in life sciences and biotechnology, especially transposable elements or jumping genes. and plant stress response. In 2007, President George W. Bush awarded her the National Medal of Science, she is also a member of the United States National Academy of Sciences, the American Academy of Arts and Sciences, the European Academy of Sciences, and the American Academy of Microbiology...

New molecular methods that add or modify genes can protect plants from diseases and pests and improve crops in ways that are both more environmentally benign and beyond the capability of older methods.
Myths about the dire effects of genetically modified foods on health and the environment abound, but they have not held up to scientific scrutiny. 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.
There's almost no food that isn't genetically modified. Genetic modification is the basis of all evolution. Things change because our planet is subjected to a lot of radiation, which causes DNA damage, which gets repaired, but results in mutations, which create a ready mixture of plants that people can choose from to improve agriculture.
Jumping genes are fundamental because they're agents of change. Everybody knows that organisms evolve. What makes them evolve is that their genes are dynamic and in motion. A familiar example is the stripe-y corn - called Indian corn - that you buy in the fall.
If there are more and more environmental refugees, they are going to end up on your doorstep too.
