Fix or famine?

The Baltic Sea isn't in great shape, due to its shape and the increasing population around its shores. That shape means that the circulation and refreshment of the water is restricted, which leads to excess nutrients, which leads to eutrophication, which leads to bottom anoxia, i.e., no oxygen in the waters on the bottom, which kills the organisms living on the bottom, or drives them away, and reduces the food supply for the fish and their habitat -- all-in-all, not a good situation.  There are two ways to address such a situation -- reduce the nutrient input, or geo-engineer a fix, like pumping oxygenated water down to the bottom.  Such a plan is going to be demonstrated, but some researchers are saying geo-engineering could make more problems than it solves.  My view is:  test and verify.  The Earth's beleaguered ecosystems need all the help they can get.  So I don't agree with not testing a pilot project.

Saving the Baltic:  geoengineering efforts to mix oxygen into the Deep Baltic should be abandoned
