There is a chance we might run out of some of the very rare metals. There are rare metals which are used in mobile phone, these are only tiny, tiny, amounts but when you think about how many mobile phone there are in the world there then it can all add up.
One way to try and make sure that we don’t run out of these rare metals is to recycle everything you can, drinks cans, mobile phones and the lid sealing the top of milk are all metal and all can be recycled. This will mean that they are there for the future use.
