Okay kiddo, so you know how when you eat candy or drink soda, it tastes sweet? That's because of something called sugar. Sugar is a natural substance that makes things taste sweet.
There are different types of sugar, but the most common type is called sucrose. Sucrose comes from plants, like sugar cane or sugar beets.
People figured out a long time ago that sugar was really tasty, and they started using it in lots of things, like making treats or sweetening drinks.
And because people liked sugar so much, there became a big industry around it. That means lots of people started growing and processing sugar to sell to other people who wanted to use it.
For example, in places where sugar cane grows well, like in the tropical parts of the world, they grow a lot of it and turn it into sugar. They have big machines that help to process the sugar cane and turn it into sugar that can be shipped to other places.
So, that's basically what the sugar industry is. A big business that grows, processes, and sells sugar to people who want to use it in things like candy, soda, and other treats.
