Ocean Water Pollution

Knowing Our Environment

Ocean Water Pollution – it does occur

An ocean can be viewed as too large a water body to pollute. However, the oceans are being polluted at a very alarming rate and in ways that can be very easily avoided. There are different ways that ocean water can be polluted and here are a few..

One of the most common ways in which ocean water pollution occurs is through discharge of crude oils into the ocean. This happens when ships transporting these oils accidentally or intentionally discharge these wastes into the ocean. These oils can also end up in the ocean through waste disposal pipes from manufacturing industries that lead into the ocean. These industries are generally prohibited by law to dump these oils out in the open and therefore, they use side tracks by having disposal pipes lead into the ocean. This oil then affects marine life of all forms including coral reefs, fish and other plant life which some fish depend on for food.

The oil makes it impossible for fish to seep out the Oxygen from the water and they end up suffocating. The plants suffer the same fate eventually. Ships transporting ores can also cause ocean water pollution when these ore sediments fall into the ocean floor. These can be curbed by regular check up on vessels before being deployed into the oceans, and implementing strict laws against industries dumping industrial wastes into these oceans.

Human waste is yet another contaminant of ocean water. Most sewer pipes lead into the oceans as a way of disposal. No matter how highly liquidized human waste is it still contains chemicals that can cause great harm to marine life once subjected to it. For instance, some of the chemicals in human waste cause the growth of macroscopic and microscopic plants which when they die and decay suck up a lot of Oxygen from the water thus causing low Oxygen levels. This then affects both fish and plant life. Human waste should therefore be properly treated instead of being dumped into the ocean.

Agriculture also plays a part in ocean water pollution. The pesticides and fertilizers used for agriculture contain some harmful chemicals. When it rains, these chemicals get drained off the plants, into water ways and eventually into the ocean. Some of these chemicals form compounds highly harmful to marine life. The less harmful alternative for agriculture would be the use of organic fertilizers which is harmless to the water as it easily disintegrates.

Cars and industries contribute to ocean water pollution as well. The fumes produced by cars and industries end up in the atmosphere and later combine with rain to form acid rain. This rain lands on the oceans with all the harmful chemicals it carries. These chemicals again can cause great harm to the fish and plants in the oceans.

Construction around ocean water banks works to create lee way for soil erosion around these banks carrying with it silt and clay which kill coral reefs. Coral reefs are a big source of food for most marine life and without this; they have little else to depend on.

Oceans are great global asset and should therefore be conserved not just for the sake of the marine life, but also because they are a source of food for humans as well.
