The term GM foods refers to those produced with the latest genetic engineering techniques. In 2000, countries that grew 99% of the global GM crops were the United States, Argentina, Canada, and China.

The next decade will see rapid development in Gm products. Gm foods may solve many of the world's hunger problems, and help protect environment.

Yet there are many challenges ahead for governments, especially in the areas of human and environmental safety, labeling and consumer choice, ethics, food security, regulation and international policy.

Many people feel that genetic engineering is inevitable and that such a technology should be put to use. However, others warn that we must take care to avoid causing unintentional harm to both human health and the environment as a result of our enthusiasm for this powerful technology.
