Excerpts;

The enormous “dead zone” in the Gulf of Mexico will take decades to recover even if the flow of farming chemicals that is causing the damage is completely halted.

A new study has found that even if runoff of nitrogen, a fertilizer chemical, was fully stemmed, the Gulf would take about 30 years to recover. Even this scenario is “not only considered unrealistic, but also inherently unsustainable”, researchers stated in the work, published in Science…

Excerpts;

More and more nitrogen keeps pouring into waterways, unleashing algal blooms and creating dead zones. To prevent the problem from worsening, scientists warn, the world must drastically cut back on synthetic fertilizers and double the efficiency of the nitrogen used on farms…

Excerpts;

China’s rapid ascent to global economic superpower is taking a toll on some of its ancient ways, patterned around the vast fisheries of the East China Sea. But now those waters are increasingly threatened by human-caused, harmful algal blooms that choke off vital fish populations, according to a new study.

The study concluded that adverse changes in the ocean ecosystem can be traced back to industry and agriculture and that the only way the process can be reversed is for humans to start addressing land-based pollution…

The green slime that washed onto Florida beaches earlier this month marks the eighth time since 2004 that toxic algae have fouled the Sunshine State’s storied coastline.

The guacamole-thick algae that fouled both coasts will likely be a regular occurrence for the Sunshine State. Here’s why…

Red tide bioluminescence. Distinctive blue flashes, a type of bioluminescence, that are visible at night in some marine environments are caused by tiny, unicellular plankton known as dinoflagellates, some of which can produce toxins that are harmful to the environment.
