The Importance of the Ocean

As we know, the ocean is the glue that holds our planet together. Nearly three quarters of our planet is defined by salty water, weaving its way around continents and circumscribing islands. So the ocean is such a ubiquitous part of our world that we mostly take it for granted.

Why is the ocean important for the human beings? Above all, the ocean has long been regarded as the cradle of life since the dawn of human history. Where there is ocean, there is life. Secondly, the ocean buffers our weather by maintaining the oxygen and carbon dioxide balance in the Earth’s atmosphere, provides us with abundant foods and many of modern medicines have been discovered from decades of relentless marine research. Thirdly, the oceans are an adequate source of life and have long been used by us for transport, for dumping rubbish and for recreation.
