What if

What if no one polluted in the ocean?

 I might help it stay that way for as long as I can.

What if no sea animals died of eating rubbish?

I could make sure that most of the endangered species in the ocean recovered.

What if there was no oil spills?

I would be able to see all the colourful, slimy and harmless fish.

But what if there were no more animals left in the sea because humans kept polluting?
