Eutrophication PSA - is the term for the process whereby water bodies receive excess nutrients (nitrogen and phosphorus) that stimulate excessive plant growth and cause algal blooms.

AL GORE: The Assault on Reason
CO2 is now absorbed into the Oceans, causing acidification and potentially toppling food chain domino #1, the plankton.
Ocean "acidification" occurs when chemical compounds such as carbon dioxide, sulfur, or nitrogen mix with seawater, a process which lowers the pH and reduces the storage of carbon.
Ocean acidification hampers the ability of marine organisms—such as sea urchins, corals, and certain types of plankton—to harness calcium carbonate for making hard outer shells or "exoskeletons." These organisms provide essential food and habitat to other species, so their demise could affect entire ocean ecosystems.
Earth's rivers polluted with cancinogenic chemicals

PARIS (Reuters) - Rivers in eastern and northern France found to be contaminated with chemicals that have been outlawed since 1987 and are proving very hard to eliminate, the government reported on Wednesday.
The River "Rhone" which runs through the southeastern corner of France (scientists said) contained dangerous levels of polychlorinated biphenyls ( PCB / PCBs ).
The latest report said additional rivers were in an even worse condition because of industrial dumping dating back decades, including the River Seine which runs through Paris.
"It's a huge clean-up job," Nathalie Kosciusko-Morizet, the secretary of state for ecology, told a news conference. Other big rivers in Europe are affected by the same problem, she said.
PCB's were used primarily as a cooling and insulating fluid for electricity transformers and capacitors. It has been banned in France since 1987 after research showed it could cause fertility, growth and cancer in humans.
Kosciusko-Morizet said PCB had been very heavily used in industry since the 1930s and France was suffering the consequences of long-standing pollution.
"Cleaning it up is far from easy. It's very complicated because there are huge amounts of sediment." She said it would be technically and economically impossible to clean up the whole Rhone River... (... what about the Ocean?)
Here is the PCB problem

with plastic pollution....

"Alguita, the oceanic research vessel from Algalita, just came back from one of its research expeditions in the Pacific Gyre, an area of the Pacific Ocean otherwise known as the Garbage Patch. They collected samples on the surface of the ocean and found evidence of record high concentrations of small plastic particles.
Birds and fish eat the plastic because it mimics the food they eat, zooplankton. Research data from the Algalita Foundation shows plastic particles outnumber zooplankton 6 to 1. Especially concerning is the fact that the plastic pieces can attract and hold hydrophobic elements like PCB and DDT at up to one million times background levels. As a result, this floating plastic is a "poison pill".
... so... the "easy" solution would simply be to get industry to stop
dumping millions of tons of toxins into the rivers/oceans....
( ... going back 50 years or so... )
... then just get the entire world to stop using plastic 'once',
and tossing it into the garbage/oceans....
... that will probably be about as easy as
oh... maybe stopping the use of fossil fuels...
then we can get back to work on that little global warming "issue".... :-)
