Question

write a note on the different types of pollutants entering our Seas and oceans ​

Answer 1

Answer:-

Pollutants which pollute water:-

1. At the time of ship's movement, oil spills from the tank and mix with the water in seas and oceans. This in turn, kills the marine animals due to eating it.
2. It also results in growth of aquatic weeds which take all the oxygen from the water.
3. This also makes the marine animals' population less.
4. In many industries, dirty water comes from and get mixed with rivers and hence also in oceans. This also make them polluted.
5. Acid rain also makes same things. (Note: Acid rain is a type of rain which is slightly acidic from natural rain. It is mainly made up of sulphuric acid and nitric acid.)

Answer 2

Answer:

Types of pollutants entering our seas and oocean

Marine pollution is caused by pollutants entering our seas and oceans. They are harmful to aquatic life. Plastic is most dangerous solid pollutants of our seas and oceans. Mankind has found plastics as an easy and cheap means of manufacturing several products. Millions of tonnes of plastics wastes such as bags, straws, bottles, etc. are carried by rivers into the seas and oceans causing marine creatures like dolphins, turtles, seabirds, sharks, etc. to die from ingestion, entanglement, and suffocation.

The carbon-dioxide of the atmosphere dissolves in the waters of the oceans and reduces the effects of global warming. But with the increase of pollution of the air, the oceans are becoming more acidic. The danger of the acidity of oceans is increasing as more acid rains are increasing.

A huge amount of industrial wastes are dumped into the rivers and oceans. When the pollution becomes very high it leads to formation of dead zones where the water is highly depleted of oxygen. These zones are death traps, marine plants and fish die there.

With the increase of sea vessels to import and export oil, accidents of oil spill are increasing. During such accidents crude oil is spilled into the sea and spread on the surface of the water. The area polluted by an oil spill may reach thousands of square kilometres killing uncountable marine fish and birds.
