Caffeinated crabs, anti-depressed dolphins, and feminized fish, oh, my! Can you imagine what would happen if sea creatures had access to your medicine cabinet? Well, they do. Pharmaceuticals from humans make their way into the ecosystem either through excretion into urine or by people disposing of old medications down the toilet. The first of these sources then flows with sewage, which has already been described by this series, out from leaking septic systems or through ocean outfalls into the sea.

Conservation, Science
Earth is facing a biodiversity crisis so severe that many conservation scientists refer to it as a mass extinction event. The International Union for the Conservation of Nature (IUCN), a professional network of 11,000 volunteer scientists belonging to more than 1,000 government and NGO agencies in 160 countries, evaluates species worldwide and determines their risk of extinction. This Red List, which ranks species in increasing risk of extinction – Least Concern, Near Threatened, Conservation Dependent, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild, and Extinct – is described as “the world’s most comprehensive information source on the global conservation status of plant and animal species”.
Statistics from the Red List are terrifying. One fifth of all evaluated vertebrate species are threatened with extinction, including 12% of birds, 21% of mammals, 30% of amphibians, and 26% of fish. On average, fifty species of amphibians, birds, and mammals move measurably closer to extinction each year. One fifth of the world’s plant species are in danger of extinction. Critical habitat-builders, including 33% of reef building coral species and 14% of seagrass species are in very big trouble.

The following photos are from a massive fish kill in a river close to la Guillec, France. According to Dr. Sophie Plouviez, the die-off affected not only fish, but nearly all of the benthic invertebrates in the river. The cause of the die-off has yet to be determined. We are trying to locate the source of the images, and will continue to update as more information become available.
