Not affiliated This course will focus on the importance of the oceans to human beings as well as the impact of human activities on the oceans. People, for example, can't survive in saltwater. Since you have no special adaptations to remove salt, if you drink too much seawater, your kidneys will try to flush the excess salt out as quickly as possible through urine, and you would lose more water than you originally drank, leaving you dehydrated. A new chapter on man's use of the oceans has been included to cover satellites and position fixing, renewable energy sources in the sea, seabed minerals, oil and gas, pollution and maritime law.
