We at Biossance are committed to ocean conservation. Our passion for protecting marine environments runs deep, from our sustainable packaging to our sugarcane-derived, shark-saving hero ingredient, squalane. And today, in honor of World Oceans Day, we’re donating 100% of our sales to Oceana, the largest international advocacy non-profit focused solely on conservation.
But saving the oceans means more than just clean beaches and healthy corals. (Although both are certainly important!) Our oceans provide vital support for all life on earth, and yet most of us know very little about them.Test your knowledge with this quick and easy quiz, then scroll down to see the answers and learn why they’re important.How Much Do You Know About The Ocean?
1) How much of our oxygen is produced by the ocean?
A) 25%B) 90%C) 50%D) 70% 2) How many animal species live in the ocean?
A) About 1 millionB) About 400,000C) More than 10 millionD) About 5 million
3) How much of the earth’s water do our oceans contain?
A) 50%B) 81.3%C) 96.5%D) 70% 4) How deep is the deepest part of the ocean?
A) 7 miles deepB) 11 miles deepC) 2 miles deepD) 25 miles deep
5) How much of our oceans have been explored so far?
A) 75%B) More than 90%C) Less than 5%D) 10%Answer Key:
1) How much of our oxygen is produced by the ocean?D) The oceans produce about 70 percent of the world’s oxygen. Most of the Earth’s oxygen comes from marine plants, such as phytoplankton and kelp. One type of phytoplankton, Prochlorococcus, is so small that millions can fit into a drop of water, and yet scientists say it provides the oxygen for one in every five breaths we take.2) How many animal species live in the ocean?A) About 1 million animal species live in the ocean.
Scientists estimate that about a million different animal species reside in the ocean. Even more exciting: we’ve only classified about 9% of them. That makes it even more important to protect our oceans, as so many cool creatures could become extinct before we have a chance to discover them.
3) How much of the Earth’s water do our oceans contain?C) Our oceans contain 96.5% of the Earth’s water.Just how much water is that? NOAA's National Geophysical Data Center estimates that there are 321,003,271 cubic miles of water in the ocean. That's enough water to fill about three hundred fifty two quintillion, six hundred seventy quadrillion gallon-sized milk containers. (And, no, we’re not making that number up!)4) How deep is the deepest part of the ocean?A) The ocean floor is 7 miles down at its deepest point.Located in the Pacific Ocean’s Mariana trench, the Challenger Deep is the deepest part of the ocean at 7 miles down. To give you some perspective, that’s deeper than Mount Everest is tall.5) How much of our oceans have been explored so far?
C) Less than 5 percent of our oceans have been explored so far.Our oceans cover about 70 percent of the Earth’s surface area, yet less than 5% has been explored. This has made protecting them difficult. After all, it’s hard to protect what you don’t know. Only about 7% of our oceans are designated as marine protected areas.
