It’s used for transportation—both travel and shipping. It provides a treasured source of recreation for humans. It is mined for minerals (salt‚ sand‚ gravel‚ and some manganese‚ copper‚ nickel‚ iron‚ and cobalt can be found in the deep sea) and drilled for crude oil. The ocean plays a critical role in removing carbon from the atmosphere and

Different types of pollution enter the ocean each year. The major pollutants are oil‚ toxic materials‚ and debris. These materials not only pollute the ocean‚ but they also affect the marine life. Before the 1970s there were no laws to prevent and stop people from dumping pollutants into the ocean. Since the early 1970s many laws and regulations

The Ocean Floor No one has ever walked the sea floor and few have even seen it. This is because of the extreme conditions found there. It is dark‚ and the temperature is close to freezing. A person standing on the sea floor would be under tremendous pressure from the overlaying water. The pressure is hundreds of times greater than the atmospheric pressure. Such a force would crush the human body. Using research submersibles which are specially designed to with stand the pressure of the water‚ scientists
