There are many animals that live under the sea. In the next slide you can see some pictures of them.
But there is also a lot of rubbish that gets thrown into the sea. After the next slide, there is a short film about how the sea is getting full of these dangerous things, such as plastic bags. They are dangerous because sea animals think it is food and they eat it.
Unfortunately, a lot of them die.
So, we have to make sure that we never let any of our rubbish get into the sea.
