It makes the Earth blue…

When you look at a globe, 70% of our planet is covered with oceans. Humans are the most intelligent form of life on Earth, but we can only live in 30% of it! The ocean is a mystery to us; there is still so much about it that we need to discover. In fact, we know more about outer space than what’s going on underneath the deep blue seas.

The ocean is where life started. There are so many species that we are only starting to discover. At first, we thought that there can be no life deep beneath the sea, since sunlight cannot reach it. We were wrong. There are all kinds of life beneath the ocean! Life that doesn’t require sunlight like we do. Fish and animals that live in environments where we can’t go.
