Biofuel is like a special kind of fuel that we can make from plants and crops. For example, we can use corn to make a special kind of fuel called ethanol. In the United States, they make a lot of biofuel from corn.
Biofuel is like a good guy for the environment because it is a lot less harmful to the air and climate than regular gasoline that comes from oil. Plus, making biofuel creates jobs for people who grow and harvest these crops.
The government in the United States wants to use more and more biofuel every year to help the environment and make our cars and trucks run cleaner. But, some people say that making biofuel can use up land and water that could be used for growing food instead. It's important to find balance and use biofuel responsibly.
