A rice farmer in Thai land wants to find a natural way to decrease the amount of insects that feed on his crops. He asks around and learns that many other farmers are adding fish to the water that the rice grows in. The fish eat the insects but do not eat the rice crops. The farmer starts using this method of growing rice, called rice-fish farming. He finds that after a few weeks of adding fish, there are almost no insects on his crops.
