You use paper in school. And all your books are made from paper. Some products are made of fossil fuels. For example, some plastics are made from oil. Most of the time, we use plastic products once and then throw them away.
Factories use a lot of energy to make packaging.
Almost everything we buy comes in a package. For example, cereal comes in boxes made of cardboard, a kind of paper. In fact, about half of all the paper made in the United States is used for packaging. Many soft drinks and fruit juices come in cans or bottles. It takes a lot of energy to make steel and aluminum cans and glass bottles.
