By studying plants and animals living deep in the ocean,scientists may find a cure for some of our most serious human diseases
We may be able to use sea plants to increase our world food supply
Engineers may learn to use the power of the sea by building huge walls to catch the force of the tides
Mining engineers may make it possible to obtain valuable minerals from the ocean

It is already known that vast amounts of minerals exist in the ocean
For example,there are at least five times as many diamonds in the sea as in mines on land
