Answer 2

1) The ocean is home to nearly 95 percent of all life.

• With so much going on well below the surface, it's easy to forget that the oceans are teeming with life. In fact, 94 percent of life is aquatic, according to the USA Science & Engineering Festival. That means those of us who live on land are part of a very, very small minority.

2) Coral produces its own sunscreen.

• Too much sunlight can damage the algae that live inside coral in shallow water. To protect the algae, which are a main source of sustenance for the coral, the corals fluoresce. This creates proteins that act as a sort of sunscreen for the algae.

3) There's enough gold in the ocean for us each to have 9 pounds of it!

• There's around 20 million tons of gold dispersed throughout the oceans. It is, however, diluted pretty much to a pulp—its concentration is only a few parts per trillion, according to the National Ocean Service. The ocean floor also has undissolved gold embedded in it, but it's not cost-effective to mine it. However, if the ocean's gold were equally distributed among every person on earth, we'd each receive nine pounds of gold.
