How is human life depends upon oceans?

Oceans covers 70% of the earth’ surface. Hence Oceans play a pivotal role in the existence of human life as well as the entire living organism kingdom.

The importance of Oceans are:

a. Biodiversity: The oceans are home to a number of species of organisms that have high biodiversity. Xample: Coral reefs, Salt marshes, estuaries, mangroves etc.

b. Natural Resources: The bottom of the Ocean floor holds minerals, including oil and natural gas, which is used for meeting energy requirements.

c. Climate and weather: As the air passes over warm waters, it rises due to warming. As it cools, condensation of the water creates rainfall. If the air passes over cooler waters, it cools and sinks. Air moves from high to low-pressure areas. Hence it has an important role in maintaining the temperature.

d. There are many other important uses like the oceans are used as transportation medium, water cycle and economy of countries.
