The ocean is an incredible and mysterious part of our planet. It covers 71% of the Earth’s surface, has an average depth of 3,682 meters (12,080 feet), and holds 97% of all water on Earth. The Great Barrier Reef is the largest living structure in existence at 2,300 kilometers long while Challenger Deep in the Mariana Trench is 36,070 feet deep – making it one of the deepest parts on earth. Coral reefs are home to 50% marine species while 80% pollution comes from human activities on land. An estimated 5 trillion pieces plastic debris can be found floating around oceans with 30 percent carbon dioxide added by humans being absorbed into them each year. Over 3 billion people depend upon marine life for their livelihoods as well as providing more than half oxygen supply needed for survival; 93 percent extra heat trapped by greenhouse gases also gets stored here annually. Despite 90 percent unexplored habitats there are over 200 thousand identified species with a $1.5 trillion contribution to global economy every year – not forgetting that Gulf Stream transmits 100 times energy generated worldwide or highest tides reaching up 16 meters high located in Bay Fundy. Lastly we have Great Pacific Garbage Patch which happens to be twice size Texas filled with plastic waste – highlighting how much damage we’ve done so far…
