Oil:A liquid fuel found deep in the earth. Gasoline and some plastics are made from oil.

Radioactive waste:Materials left over from making nuclear energy. Radioactive waste can harm people and the environment if it is not stored safely.

Recycling:Away to reuse materials instead of just throwing them away.

Recycle mark:A design of three arrows that make up a circle. This mark tells you that you can recycle the product. It can also mean that the material is made from recycled materials.
