2. Oceans Cover 70% of Earth’s Surface

There is a lot of water on Earth. So much that is covers around 70% of Earths surface. This figure is likely to increase as the polar ice caps continue to melt. Some of the oceans are so deep that we have only just been able to reach the bottom and we have explored just a tiny fraction of them.

Of all the water that exists on Earth, about 97% of it is salty. While this is not suitable for us, the saline oceans are rich with life and harbor some of the most diverse habitats on the planet. Rich in life, the oceans are also a very important source of our food.
