The oceans provide modern society with numerous resources. For centuries the ocean has provided humans with things such as food, clothing, shelter materials, and a way of transportation. In today's world more than half of the resources that humans use are derived from the ocean. The oceans and seas of the world provide countless amounts of physical and biological resources. These resources include mineral deposits, oil and gas, electrical energy, food from marine animals and plants, transportation and recreation. Unfortunately many types of marine resources have been mismanaged and over-exploited, and their future sustainability is uncertain.
             There are two main categories of resources that are derived from the ocean.
             Biological resources are marine animals and plants harvested for food and other uses. Physical resources are of non-living resources that are harvested. Both biological and physical resources play an important role in everyday life.
             There are many physical resources that are derived from the oceans. Some resources include petroleum (crude oil), gases, and minerals. Petroleum and natural gases form from the buried remains of marine plankton. Petroleum and natural gas pumped from offshore drilling platforms contributes substantially to the world supply of energy, oil, and vehicular products. If you look around you, everything made today has something to do with oil and gas. The car you drive runs on motor oil and gas. The heater in your house is powered by electricity from a power plant. Your computer is made at a factory that probably burns some form of oil or gas to make the computer parts.
             Oil and gas cause the most amounts of pollution and problems in today's world. It seems like all world problems are due to the extraction and exploitation or crude oil and gas. The problem with deriving oil and gas is much too obvious; pollution. What happens when an oil tanker runs-agr
