3 Fun Facts About The Ocean
The sea is truly fascinating. This body of saltwater covers 71% of our planet’s surface and hides numerous undiscovered beings and historical artefacts from the past. Since most of Earth’s surface is covered by water, there is a lot to be explored – and a large part of it is yet to be studied. In fact, it is estimated that only 5% of the sea has been explored.
70% of the planet’s oxygen is produced by the oceans.
How impressive is this? Around 70% of all the oxygen we have comes directly from the seas. It is produced and released into the atmosphere by marine photosynthesizers, such as phytoplankton and seaweed, which are the true lungs of the world.
