What is Oceanography ?
The branch of science which deals with the study of ocean and the sea and their relation to the earth is known as oceanography.
The major problems ocean facing at present
Ocean is the repository of several living organisms including micro and macro organisms. It also plays a vital role in maintaining natural diversity. They can use Carbon dioxide most effectively for reproductive purpose. The billions of green organisms in the sea use Carbon Dioxide for the food making process. Majority people of our country depend upon the richness of fish in the ocean for their existence. It gives food as well as job for them. The oceans which play a major role in Eco-system are now in a miserable state due to some evil doings of men. Let us examine those problems.
The oil mining in the sea cause to the spread of a great extent of oil in the sea. The crude oil which is transported through the ships, petrol, diesel, the fluid leaked out from the oil tank of the ships, accidents of the tanker extra are the major sources of oil spread in the sea. It destroys the marine animals.
The over exploitation of the resources of the sea may affect the proper existence of the sea. The over exploitation of the resources also harmful to the richness of fish in the sea.
Industries may cause to the overflow of polluted water in to the sea directly or indirectly. Insecticides, chemicals, oil, plastic, things extra also reaches in to the sea to a great extent.
While increasing the amount of Carbon dioxide in the atmosphere, the ocean also absorbs more amount of Carbon Dioxide simultaneously. It may cause to the increasing of acid nature of the ocean water. This is known as acidity. This also leads to the destruction of living organisms and the changes in weather.
Wastes from the ship
Along with the fuels, the liquids came out from the ship and the plastic wastes left out by the sailors also became a major challenge to the sea.
We can't imagine a life without the ocean. So, it should be preserved. Celebrate June 8 as the World Oceans Day every year.
