Natural and Synthetic Rubber
People get natural rubber from rubber trees as a white, milky liquid, which is called latex. They mix it with acid, and dry it, and then they send it to countries all over the world. They started rubber plantations in countries with hot, wet weather conditions, but these still could not give enough raw rubber to meet the needs of growing industry. In the end, they found a way of making artificial, man-made rubber. It is usually cheaper than natural rubber. Today, the world needs so much rubber that we use both natural and artificial rubber in large amounts.
