Biodiversity is meant by Life on Earth and comprises marine biodiversity 'Life in the Seas and Oceans. The marine culture has a very high biodiversity because 32 out of the 33 narrated animal phyla are rendered in there.

Biodiversity loss and climate change concurrently menace marine ecosystems, yet their interconnection remain vastly unknown. Ocean fermentation severely influences a wide variety of marine organisms and recent studies have predicted crucial effects at the pH conditions expected for 2100.

Why is marine biodiversity important?

Marine organisms bestow to many risky processes that have direct and indirect outcome on the health of the oceans and humans. What is obvious is that there are specific species and functional groups that play critical roles in important ecosystem processes, and the loss of marine biodiversity is incapacitating the ocean ecosystem and its potentiality to resist disturbances, to adapt to climate change and to play its role as a global ecological and climate regulator.

The ocean is home to millions of species. The health of the oceans is firmly dependent upon this marine biodiversity. Life in the ocean is vital component of climate regulation. Climate change because of human activity has a direct effect on marine species. It changes their abundance, diversity and distribution. Their feeding, development and breeding, as well as the relationships between species are pretentious.

According to species, rising temperatures lead to different behaviour patterns. The ocean fermentation, caused by an increasing osmosis of atmospheric CO2, has a quickest outcome on the marine organisms with calcareous skeletons or shells: these presume phytoplankton, crustaceans, molluscs…
Severe climatic events exhaust natural environments, for example by erosion and flooding. They disturb marine life in coastal areas, particularly in certain coastal habitats such as mangroves and sea grass beds, which are essential breeding grounds as well as prospective CO2 capture zones.
