Research carried out by Chinese scientists has discovered that GM crops are damaging the environment, despite their success in controlling the bollworm pest

Research carried out by Nanjing Institute of Environmental Sciences (NIES) under the State Environmental Protection Administration (SEPA) found that fields planted with BT cotton (which contains anti-bollworm genes) contain fewer insects and a higher concentration of pests than other areas.

Bacillus Thurengenis (BT) transgenic cotton makes up 35 per cent of China's crop, and last year was planted in an estimated area of 3.71 million acres.

The scientists also discovered that BT cotton loses its resistance to bollworm after being planted for eight to 10 years continuously.
