Insects are a very healthy food. They have almost as much protein(蛋白质) as meat from a pig or cow and are low in fat. Eating insects is also very good for the environment since they need less land and water than larger animals.

Marcel Dicke, who studies insects, explained in a talk how insects also produce more meat from the food they eat. For example, imagine a farmer feeds a cow 10 pounds of food. Those 10 pounds of food produce about 1 pound of meat for people to eat. However, imagine the farmer gives a certain number of insects 10 pounds of food. Those 10 pounds of food produce 9 pounds of meat for people to eat!

Eating more insects can also help people in poor areas. Many people can raise and sell insects, which can provide jobs and food.

But insects will not replace(替代) animal meat very quickly. First, people in some countries would have to change how they think about eating insects. Many people in North America and Europe eat a lot of meat like beef and pork. But they don’t traditionally eat insects. In fact, for many people in the west, eating insects sounds crazy! They believe insects are dirty and dangerous. Insects make them feel uncomfortable.

Some people are trying to deal with this problem. For example, David George Gordon wrote a book named Eat-A-Bug Cookbook, which tries to show people that insects can be delicious. Other insect experts travel around telling people about the benefit(益处)of eating insects. But they still have a lot of work to do.
