Experts say some farming activities are seriously damaging Earth s environment.
Bad farming methods can damage soil, forests and water supplies. They also have caused some plants and animals to disappear. Two groups now say that bad farming methods are threatening the ability of farmers to produce enough food to feed the world population in the future. The International Food Policy Research Institute and the World Resources Institute reported the findings. The groups used satellite images, maps and modern equipment to study the effect of agriculture on the environment.
