Toxic Blue-Green Algae Kills More Than a Hundred Elk
A hunter stumbled upon a bizarre sight on a 75,000-acre ranch north of Las Vegas, N.M., on Aug. 27: the remains of more than 100 dead elk. Livestock deaths are not unusual, but so many animals dying off, and doing so in what seems to be under 24 hours, was puzzling to scientists

Officials with the New Mexico Department of Game and Fish investigated the mysterious elk deaths and ruled out several possible causes for the elk deaths, including poachers, anthrax, lightning strikes, epizootic hemorrhagic disease (an often-fatal virus known to affect deer and other ruminants), botulism, poisonous plants, malicious poisoning and even some sort of industrial or agricultural accident.

Through science and further testing of elk tissue samples and water samples, it was determined that pond scum was the culprit. Or, more specifically, a neurotoxin produced by one type of blue-green algae that can develop in warm, standing water.

Verona New Jersey to go Phosphate-Free? - Phosphates enter waterways from human and animal waste, phosphorus rich bedrock, laundry, cleaning, industrial effluents, and fertilizer runoff. These phosphates become detrimental when they over fertilize aquatic plants and cause stepped up eutrophication. If too much phosphate is present in the water the algae and weeds will grow rapidly, may choke the waterway, and use up large amounts of precious oxygen (in the absence of photosynthesis and as the algae and plants die and are consumed by aerobic bacteria.) The result may be the death of many fish and aquatic organisms.
