One of the biggest research findings has been the development of new strain of wheat and rice. Scientists in every continent have adopted the new types of rice and wheat. Breakthroughs may soon lead to another big change or "revolution" in agriculture. Scientists are changing living things by altering their genes. Through "gene-splicing", nature itself can be changed quickly. Food plants may be improved to do a better job of fighting off insects and weeds, with fewer pesticides. Plants may become better able to reproduce themselves each year. Changes in genes can also make grains and other plant foods better. These changes would make farming easier and more productive.
