How can we save the oceans?

Three quarters of our planet is covered by 5 oceans that are joined up.

This huge surface area has valuable natural resources, such as fish or oil.

The oceans are vital for humans because they produce half of the oxygen we breathe.

So, how can we take care of them?

Sadly, humans have been taking from the oceans without worrying about the consequences for 50 years.

Overfishing, too many oil wells and the huge number of polluting ships have degraded the oceans.
