Oil and Water

Oil spills into the water and when oil hits water animals under the sea are in danger. Oil can be caused by a tanker full of oil smashing into a ship. 

The oil can kill seals by poisoning their food. Oil can kill dolphins by blocking their blow holes, this makes it hard for the dolphins to get air above the water so they can breathe under water. Oil can kill birds too, if oil hits the birds feathers the bird will fall and be freezing cold on the floor.
