Extinction Of Marine Life

All the organisms living in the water bodies come under marine life. Plants, animals, and other organisms in seas, oceans, saltwater, and other water bodies are related to marine life. Marine life is believed to be the most beautiful gift given to us by nature. There are so many sectors linked with marine life and providing millions of people with job opportunities. But nowadays humankind is failing due to its toxic nature. If this isn't addressed on time the results will be irreversible.

There are several initiatives taken to converse the aquatic habitat of marine life. Marine conservation is known as protecting and preserving aquatic ecosystems by a proper management plan. It is a new concept that has been developed to address the issues like the extinction of marine life and exploitation of the natural habitat of these organisms. This issue has also been addressed in the sustainable development goal to provide and ensure the use of sustainable marine resources.

The world's average temperature is slowly rising. This will gradually increase the risk of extinction of aquatic animals. Marine organisms are disappearing from their natural habitat at a very fast rate as compared to the living organisms on the land. It is believed that the warm-blooded animals that are the land animals tend to have more resisting power and better adaptability to climate change than the aquatic organisms i.e. the cold-blooded animals. This identifies the major risk to aquatic animals.

The carbon dioxide from the pollution is absorbed by the ocean and traps the atmospheric heat under water resulting in the rise of temperature. The scientists have calculated a “ thermal safety margin” for more than 318 terrestrial organisms and 88 marine species depending upon how much temperature/ heat they can resist. They have found that many of the aquatic species have already disappeared from their natural habitat. The rate of disappearance is twice that seen on land. Lands animals tend to be at lower risk than aquatic animals because they have external sources to take shelter from the heat but aquatic organisms do not have that option.
