The Ocean’s Vast Unexplored World

We know more about outer space than our own oceans. Eighty percent of the ocean remains

completely unexplored and unmapped. Every time scientists venture into the deep sea,

they discover species that have never been seen before. The ocean produces over half of the

oxygen we breathe through microscopic organisms called phytoplankton. These tiny plants

are smaller than a grain of sand but keep our entire planet alive. The Pacific Ocean

alone covers sixty three million square miles. Scientists have identified two hundred
