Ocean Myths:

Ocean is the subject we know a little. Hardly can I imagine we've better known about the moon than our oceans on the earth. We've only explored less than 5% of the ocean. It is hard to imagine we are living on the tiny land surrounded by the great ocean. But we've just known little about it. And more importantly, it's so hard to determine how important and influential the ocean brings to our daily lives, for example, oxygen and water.
