Ships use the oceans and seas to transport the world’s cargo.
Many countries of the world depend almost entirely on the sea for their food.
The marine environment must be protected from pollution by everyone.
Pollution can cause serious harm to or even kill the plants and animals
that live in the sea. To help protect the marine environment,
international regulations place strict laws on ships.
All the animals in the sea feed off a range of marine animal or plant
life. If the plant life is harmed by pollution this impacts on the
lives of all animals such as fish, crabs, crayfish etc.
