One of the most prevailing topics for the health of our oceans today is the issue of plastics. From the bottles discarded on the beach to the micro plastics that wash down our drains  there is clear evidence that the volume is steadily growing.  With reports that there will soon be more plastic particles in the sea that fish, what is the science behind the story and how concerned should we be.  Can we see the "Pacific Garbage Patch" from space and how wide spread is it?  More importantly can we reverse the trend and return our fragile ocean environment to a pre-plastic time?  These and other issues will be covered in this talk.
