Transport

It is estimated that, by volume, 80 percent of the world's international trade is carried on the oceans. Ships are extremely efficient at carrying large amounts of bulky goods over large distances.

The main types of bulk goods are: crude oil and petroleum, iron ore, grains, coal, phosphate and bauxite. Container ships are used to haul manufactured goods and foodstuffs in specialised vessels.

Such a major industry has impacts on the environment, whether from accidents, pollution or the facilities for building, harbouring or servicing ships and their cargoes.
