📖 Read the story
Scientists are studying tiny living things called bacteria. These bacteria live in our stomachs. But now, scientists use them in a new way. Usually, we use oils from trees to make soap and medicine. This is bad because people cut down many forests. This hurts wild animals. Now, scientists have a better idea. They give food waste to the bacteria. The bacteria eat the waste and make special chemicals. These chemicals help us make soap. This is called ‘green science’ because it protects nature. We do not need to cut down trees anymore. Scientists say it is like cooking. If the bacteria have the right food, they work very well. These tiny helpers are very busy! They help keep us clean and they keep our Earth healthy too. It is a great way to save our planet.
