For the Vandana Shiva will never forget a lesson she learned at the age of 13. Her parents insisted that she should wear clothing made only of homespun cotton. One day, Vandana, having returned from a boarding school to her home, demanded a nylon dress, the fashion followed by her rich friends. Her mother agreed. “If that is what you want, of course you shall have it,” she said. “But remember, your nylon dress will help a rich man buy a bigger car. And the cotton that you wear will buy a poor family at least one meal.” Did she buy the nylon dress? Of course not! Maybe this experience led to her resolution to fight for social justice in her later years. Now 60, ever visiting Taiwan in 2010, Vandana's main concern these days is how to preserve Indian traditional crops. This is severely attacked by many global companies. They encourage farmers to grow so-called high-yielding crops; many farmers, therefore, turn to high-tech methods and depend on bioengineered seeds, chemical fertilizers and pesticides. As a result, hundreds of traditional crops are disappearing. Contrary to expectation, high-tech agriculture can not rescue Indians from starvation. Bioengineered seeds are expensive and cannot adapt to local conditions. Hundreds of Indian farmers have committed suicide during the past five he world ironment. ns in 1970. years because of failed harvests. But there is hope. Many farmers are returning to traditional methods promoted by Navdanya, an organization based in New Delhi that Vandana helped found 20 years ago.

It also helps local farmers form their own self-supporting organization and seed bank. nean? +明一 生能但奇 63
