Creativa. Pollution at sea

Pollution at sea.

Today we are going to speak of the pollution at sea and how affect this theme with the forming the ocean.
Every year, the sea is more polluted than other years and it is very worrying because if the Earth is very contaminated in a few years, can be finished destroying and all the work that the Earth do to create a ocean, in few years could be destroyed.

I leave my powerpoint that I have to explain the pollution at sea.
