Preserve Our Ocean Life

As we know that nearly ¾ of the earth’s surface is covered by water. The deep and wide oceans, they are the homes of countless living creatures from the smallest to the biggest one.

Our world has four oceans namely: Arctic, Indian, Atlantic and the Pacific. The biggest of them is the Pacific. It is the biggest and deepest ocean among them.

The ocean has two main zones, the ocean basin (the deepest part) and the shallow continental shelf at the edge of the land. Along the coast, the seashore forms a constantly changing margin between sea and land. There are different types of shoreline where coastal rocks are soft, features such as clefts change quickly. Hard rocks wear away slowly. Even the everyday action of a relatively calm sea will erode the shoreline.

The oceans have been used by humans for thousands of years. It became their source of food, means of transport in ships, and as a dumping ground for waste. Fishing is an ancient human activity. Humans are not satisfied by the way they catch fish. They try to discover modern ways on how to catch large amount of fish. They use modern vessels, large nets, devices such as radar for tracking fish shoals. Today, valuable food fish are becoming rare in areas where they once numbered millions. Because of the modern fishing methods that are simply too efficient. Nets often trap immature fish which have not yet been able to breed.

The oceans have become a dumping ground for all kinds of rubbish. Every year more than 3 million tons of oils are spilled into the sea. Much of this is washed out of the tanks of oil tankers before they reload. About half of the pollution of the oceans is caused by waste dumping. Domestic wastes are being dumped into the sea. These cause problems, because they will not decay naturally and so remain a lasting danger to wildlife. Chemicals are often toxic to people, as well as to fish.

The whales were also sea living creatures. Today, whale hunting become so relevant because of the demand of whale oil and other product s that comes from whale. How can we save our whale if nations will not cooperate in whaling bans which can help save the little remaining species of whales?

The coral reefs are the earth’s oldest living communities. Most of them are between 5,000 and 10,000 years old. They are rich in wildlife species like the rain forest. A single reef may contain 3,000 species of coral, mollusk, crustacean and fish. The delicate population of reefs is easily damaged by the population of the water, removal of coral for sale as a souvenir and over-hunting by spear fishers. How can we protect them if we try to continue on abusing them.

Such attitude of humans if not being change will make our world lost its sea living creature. Let’s remember that these species are a great help to us. Help preserve our sea living creatures. Let’s support government program in protecting them. Let’s take care of the beauty of nature that God has given us.
