A genetic plant sterilisation technology, known as the Terminator gene, that is heralded by scientists as a possible solution to the ecological problem of gene drift, is being scorned by many environmentalists. The United Nations Convention on Biological Diversity, which is being held in the Hague this week (15-19 April), is examining the issue of whether plant sterility genes should be banned internationally. So far, India is the only nation to ban the technology, although the technology is not being used in any nation.
