Saving the Ocean’s Dead-Zone: Will Oxygen Help?
Humanity has not taken heed to the dumping of sewage, fertilizers and industrial pollutants in the seas and rivers of the world. In some coastal marine areas, the percentage of nutrient waste such as phosphorus and nitrogen has caused an extensive growth of algae and plants that eat up the oxygen in the water and literally kill off the other marine life. Various areas around the globe have experienced an increase in ‘red tide’ occurrences as well as the size of the red tide itself. These are explosions in growth of algae that consume the oxygen and release a toxic ‘bloom’ that causes marine life to die in unparalleled numbers. Beaches are covered in dead fish, as they die and are washed ashore. Some areas of the U.S. have established new laws regarding the addition of fertilizers, the type and time allowed to use; but this will not be enough to turn around the effects. According to the WRI (World Resources Institute), there are now over 530 aquatic dead zones around the world, totaling over 95,000 square miles and scientific data is indicating that climate change may be actually making the situation worse.

Maybe pumping oxygen back into the ocean will help. It would be good to hear a follow up on this, to see if this actually worked. If it does, then it could be shared with all of the other countries that have dead zones and maybe we can do some good, instead of harm to the ocean.May 27th, 2013 at 4:15 pm
If we don’t stop the destruction, there will be more and more areas that will be dead zones. I can remember seeing what was called a fish-kill. Thousands and thousands of dead fish on the shore, due to pollution and an algae bloom. It looked like someone set a bomb off and the fish paid the price.May 26th, 2013 at 12:39 pm
As long as we don’t have to see it, the dead zones aren’t a priority. It’s been in the news a lot more recently and good to hear that some top scientists are trying to work on fixing another area of damage that we have created. It may set off a light bulb for those people that wonder why so many parts of the world are having algae blooms (also known as red tide). When it hits their favorite beaches, they will finally pay attention.May 25th, 2013 at 4:08 pm
