An Ocean of Change 

The Ocean is the heart of the world. Water covers more than two-thirds of the Earth’s surface. Sea plants, like Posidonia, produce 70 of the oxygen we inhale, and the deep waters are home to wildlife and some of the largest creatures on the earth. It provides us with food, jobs, life, entertainment, and sailing! Without it, we can't survive. 

We need to protect its future because of the following reasons:

1. It helps us breathe

Phytoplankton that live in the ocean are responsible for at least 50% of the oxygen on Earth. They contain chlorophyll to capture sunlight and use photosynthesis to convert it into the energy they need, producing oxygen as a derivate. They also consume carbon dioxide, transferring about 10 gigatonnes of carbon from the atmosphere deep into the ocean each time.

2. It helps regulate the climate

The heat tends to be at its most violent nearer the ambit, with the water nearest the face warming the most. Sea currents also transport that heat around the world; north and south, towards the poles. As some of the ocean water evaporates it becomes thick and heavier, due to its fairly advanced swab content. That causes it to sink, taking some of the warm water deeper.

3. It’s an important source of food

Fish is on the menu for billions of people around the world every day. It accounts for nearly 16 of all protein consumed worldwide. Of course, there’s further to seafood than fish, crustacea and other comestible brutes. A range of algae and ocean shops are also generally used in cuisine.

 Also, to get just one gram of protein from cattle, one needs 112 litres of water. The abysses, if duly managed and maintained, could form an important part of a more sustainable approach to feeding the earth’s growing mortal population.

4. Its biodiversity is inconceivable

It’s not just a source of food. The ocean is also home to a cornucopia of life. While estimates on the number of species that live in the ocean live, no one knows with absolute certainty what that number is.

5. It creates millions of jobs

By 2030, ocean-grounded diligence will employ further than 40 million people worldwide, an OECD report estimates. A huge share of those jobs is likely to be in the fisheries sector, followed by tourism.

The profitable health of maritime diligence is unnaturally linked to the overall health of the abysses, of course. Ocean frugality is of particular significance in developing countries, which are home to the utmost of the 3 billion people who calculate on the ocean for their livelihoods.
