Plastic is being thrown into the ocean. It is something that cannot be digested by the earth. Plastic never goes away. There is always a piece of it that still exists It releases toxic chemicals as well. The garbage patch with the plastic waste that is in the ocean has been accumulating rapidly. The animals around this patch are starting to die off because they are dying of starvation because they can’t get enough food. They are also getting dehydrated because they cannot get to their water source. The largest of these patches is about the size of Texas. It contains about 3.5 million tons of garbage. Most of this being plastics. This is found midway between Hawaii and San Francisco. To help with this, people should try to recycle anything they possible can and to not just throw garbage anywhere, but to dispose of it properly.

Mining these minerals is difficult because the sediment is not easy to bring up to the surface. Thus, the bottom of the ocean becomes damaged over time because of the mining of the sand, dirt, and gravel that is being brought to the surface along with other minerals. Mining in the ocean is beginning to become difficult because it is not easy to bring what is being mined to the surface. The bottom of the ocean is being destroyed. Mining is tearing up the sand, dirt, and gravel and these things are being pulled to the surface along with many other minerals. The mining machinery is also damaging the bottom of the ocean and its coral reefs.

Ships shipping the mined minerals release air pollutants in the form of sulphur dioxide, nitrogen oxides, carbon dioxide, hydrocarbons, and carbon monoxide. Chemicals that are dumped include chemicals from the ship, cleaning chemicals for machine parts, and cleaning supplies for living quarters. Also, the ships sewage is not always treated properly. It is sometimes not treated at all. Shipping has an extremely low impact on the ocean, but that doesn't mean it doesn't affect anything in the ocean. The only thing that is bad about shipping would be the oil spills or when they dispose of their waste in the ocean. Another thing that is bad about them is that the modern engines create water pollution when they are used. Ships and other watercraft engines disturb the environment with loud noises, large waves, and hitting and killing animals. The most hit animals are manatees and dolphins. Some conservation that is being done is the use of wind-powered boats for shipping and travel. The use of the wind allows boats to not rely of engines that release pollutants into the water.

Coral is not plant or rock. It is composed of fragile animals that are called coral polyps. Coral polyps form thin layers on large coral reefs, which are mounds of dead coral polyp skeletons. These are always just re-layering themselves. Ten percent of the worlds coral reefs have been completely destroyed. In the Philippines, where coral reef destruction is the worst, over seventy percent have been destroyed and only five percent can be said to be in good condition. Statistics say that by the end of the century all tropical coral reefs will be disintegrating because of the acidity in the oceans. It is caused by the build-up of carbon dioxide that has been found in the atmosphere. Carbon dioxide from the air dissolves into the sea over time. The coral reefs begin to disintegrate when the acidity rises above a certain point. 10% of the world’s coral reefs have been completely destroyed. In the Philippines, where coral reef destruction is the worst, over 70% have been destroyed and only 5% can be said to be in good condition. The way to help with this problem is people trying to use things that do not give off large amounts of carbon dioxide.

200 billion pounds of fish and shellfish are caught each year. The tourists that come to these oceans eat an excessive amount of the local seafood. When oil and pollution is being dumped into the ocean, it is harming and killing a lot of the organisms living in the water that they use for the food. In many countries, commercial fishing has found more economical ways of catching fish, including gill nets, purse seines, and drift nets. Although fish are trapped efficiently in one day using these fishing practices, the number of fish that are wasted this way has reached 27 million tons per year. Also, habitats have been destroyed that are essential for the repopulating of the fish. In addition, marine mammals and birds are also caught in these nets. Overfishing can turn the ecosystem upside-down and leave huge amounts of dead things in the water. Other human activities like trawling and dredging of the ocean floor have bulldozed over entire underwater habitats. The oyster habitat has also been completely destroyed in many areas from sediment buildup draining from farm runoff.

Phytoplankton accounts for possibly 90% of the world's oxygen production because water covers about 70% of the Earth and phytoplankton are abundant in the photic zone of the surface layers. Some of the oxygen produced by phytoplankton is absorbed by the ocean, but most flows into the atmosphere where it becomes available for oxygen dependent life forms. The phytoplankton is dying because of the many oil spills that have occurred.
