what would happen if noone recycled?

We recycle to save the world's resources. For example, there is a limit to the amount of oil from which we can make plastic, and aluminium ore to make drinks cans. Resources that run out eventually are called 'finite resources'. By recycling these materials we can save finite resources for the future. By recycling, we also reduce the amount of rubbish which ends up in rubbish tips (also called landfill sites).
If no one recycled, we would eventually run out of finite resources and space to bury rubbish.
