About Sharks
Sharks have fascinated and terrified man for thousands of years. Although 'shark attack' is one of the ways media companies get attention, only 10-15 people are killed by sharks each year, while humans kill over 100 million sharks annually. Many shark populations are threatened with extinction.
About Water
Water is by far the most important substance on Earth. Water covers over 70 percent of the planet and makes up between 50 and 75 percent of the human body. In fact, it's one of the only things we are positive needs to be present for life to exist. When scientists look for life in our solar system and on exoplanets, they are looking for liquid water.
