-Protecting soils to help combat climate change
-Overfishing linked to algal blooms
A new study by Swedish researchers found that, along with nitrogenous runoff from livestock raising and agriculture, algal blooms in the Baltic Sea are linked to the decline of certain species of large fish. Specifically, the research showed that if perch and pike fish populations were healthy and no nitrogen pollution existed, the surrounding waters had only a 10% chance of being afflicted by an algal bloom.
However, in areas where fishing had caused their populations to be substantially reduced, the chances of an algal bloom went up to 50%. The researchers believe that the increase is related to a disruption of the food chain, which in turn affects the ecosystem. Swedish scientists, we appreciate your work that sheds new light on our oceanic environments.
