The Final Fronteir

Something said in class made me wonder... why do we spend so much on exploring things that are out of reach when we know so little about that which covers 71% of our world?

'An estimated 80% of all life on earth is found under the ocean surface and the oceans contain 99% of the living space on the planet. Less than 10% of that space has been explored by humans. 85% of the area and 90% of the volume constitute the dark, cold environment we call the deep sea. The average depth of the ocean is 3,795 m. The average height of the land is 840 m.'

There is more to find in the deeps of the ocean than there is on land, but we have only scartched the surface.
