In the U.S., we think of bugs as pests, not dinner—but scientists say that may soon change. In the future, we’ll need additional food sources because there will be more people. In just the next 30 years, Earth’s population is expected to grow by about 2 billion people.
At the same time, climate change could damage our food supply. Heat waves, floods, or droughts can make it difficult for farmers to grow vegetables, grains, and fruit.
Think of it this way: A field of corn takes at least two months to grow, and it can be wiped out by bad weather pretty quickly.
In contrast, insects multiply and grow fast, and some can even lay thousands of eggs at a time. In a matter of days, these new insects can reach adulthood.
Furthermore, eating bugs is more sustainable than raising cattle, pigs, and other animals because bugs require less land, water, and food. Farming bugs also creates less waste because people eat most or all of the insect. With other animals, we eat only certain parts.
