According to oceanservice.noaa.gov the oceans produce 50% of the Earth’s oxygen. However most if not all of this oxygen is consumed by marine life.  According to oceanservice.noaa.gov  dead plants and animals use oxygen when they decay in the bottom of the ocean.  For these reasons it is imperative that we keep our oceans clean.  
 

Some of the ways we can do this are through picking up rubbish while out on our daily walks, participating in cleaning bees and trawling for rubbish in our oceans and waterways.  We can also refrain from pumping untreated human waste into the ocean and legislate to protect our oceans by establishing marine parks and to restore our coral reefs.

Climate Change is also responsible for changes in the ability of the oceans to support life.  This issue needs to be addressed.

We can restore the health of our oceans by local and global advocacy and action.
