dos transgénicos

"All over Africa and Asia there are publicly funded efforts aiming to create transgenic varieties of subsistence crops that will be of benefit to poorer farmers and will be made available without licensing restrictions. A quick survey of of some recent initiatives includes salt-tolerant rice for use in degraded land where salinisation is reducing yields; a pest-resistant eggplant developed by a university in the Philippines; Vitamin A-fortified mustard in India that could avoid 46,000 unnecessary deaths per year; disease-resistant rice in Uganda; so-called 'iron beans' in Twanda to reduce anaemia in pre-school children and women; and an African banana that is resistant to devastating wilt disease courtesy of a gene transferred from the green pepper. I am often told that genetic engineering means monoculture by definition, and will therefore eliminate crop diversity — but there is no logical reason why this must happen either. The International Institute of Tropical Agriculture, for instance, which is behind the disease-resistant transgenic banana, also works to support the biodiversity of traditional crops: in September 2010 it helped launch a 'yam bank' in Nigeria to collect, store and preserve some 3,000 varieties of this important subsistence crop. The two strategies can go together."
