That day I was wondering: what if in this world, there is no marine lives? I'm thinking: then this place is not for human.

Lets see what these marine lives have done for us:


The Coral Reefs:

• They provide the home for 25% of all marine species.
• They provide ingredients for the cures of many diseases and illnesses. For example, Secosteroids, an enzyme used by corals to protect themselves from disease, is used to treat asthma, arthritis and other inflammatory disorders. 

The Marine Plants:

• They absorb the carbon dioxide in the ocean to produce oxygen in exchange. 
• They help to trap the green house gases such as methane that is building up in the seabed.
• In short, they are keeping the Earth from getting warmer.
• Without these marine plants, global warming will become the world's greatest problem.

Fishes:

• Fishes can be considered as a primary source of protein for billions of people on earth.
• They helps to maintain a balance in the ecosystem of the ocean.
• Without fishes, the entire running marine ecosystem will be brought down to a halt, as millions of other marine lives will be starving to death.

Other marine animals:

Sharks:

• Sharks may seem menacing in movies, but they play a vital part in the ocean. Without sharks, wastes in the ocean will continue to build up. They act as filter feeders that consume large quantities of zoo-plankton, such as cope-pods and krill, keeping the ocean water clean and easier to be filtered for consumption.
• Interesting, sharks have extremely strong immune systems which give hopes to researchers to derive a new cure for deadly diseases.
• Sharks are inspirations for mankind. A lot of inventions are made because of them and we, being the benefited, should protect them.
