The truth about GM

Will GM technology feed the world - or destroy farming, and human health, in the name of corporate profit? How can we tell, when the science is up for sale?

Genetically modified crops might once have proved useful. In the early days, in the 1980s, scientists I spoke to in India hoped to transfer genes from groundnuts (which are very resistant to heat and drought) into sorghum, the staple cereal of the Sahel, which is also drought-resistant but succumbs in the worst years. In California, there were advanced plans to produce barley that could thrive in brackish water of the kind that is spreading worldwide in the wake of overzealous irrigation. In Brazil, just a few years ago, I found GM being used to make disease-resistant papaya - which grows everywhere in the tropics and is an instant, free source of succulence, energy and Vitamin A. I was all for it.
