Insects (昆虫) 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 do not 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 “The Eat-A-B ug Cookbook”, which tries to show people that insects can be delicious. Other insect experts travel around telling people about the benefits (好处) of eating insects. But they still have a lot of work to do.

Khan Academy is a website providing a free education for any person. The website includes more than 4,000 short teaching videos about many different subjects. Every month, over 7 million people go to the Khan Academy website to watch its videos.

Khan Academy began with one man named Salman Khan. As a young man, Khan got a degree from Harvard Business School and began to work in business.

In 2006, Khan used the Internet to help his young cousins, who lived far away, with their mathematics schoolwork. He drew numbers and pictures on the website to teach them. After a time, he put his videos onto the website YouTube, where his cousins could watch them any time they wanted. But Khan noticed that other people were also watching his videos on YouTube.

By 2009, the number of people watching his videos on YouTube was getting very large. Khan decided to make the videos his job instead. So he officially began Khan Academy, providing videos on mathematics and other school subjects.

People did not have to pay to watch the videos. But they could give Khan money if they wanted to support (支持) his work. Some people did give Khan small amounts of money, but he was still having a hard time. Later, a woman told Khan that Bill Gates uses Khan Academy for his kids. After that, the Bill and Melinda Gates Foundation began giving money to Khan Academy. In 2010
