25% of Montrealers + antidepressants = eco-decline

Ecosystem (ē’kō-sĭs’təm, ĕk’ō-) noun: An ecosystem is a biological environment consisting of all the organisms living in a particular area, as well as all the nonliving, physical components of the environment with which the organisms interact, such as air, soil, water, and sunlight.

We are, in fact, all connected.

From Care2 (obnoxious bolding my own):

According to a recent research study about 25 percent of Montreal residents take an anti-depressant, and human waste that enters the Montreal sewage system contains these drugs. The system is similar to sewage treatment facilities in other major cities around the world, so there is some chance a similar effect may be occurring there as well. The Montreal system treats solid waste but does not disinfect wastewater, so anti-depressants are present in the system, which empties into the Saint Lawrence river ecosystem. Researchers found anti-depressants accumulate in fish and can alter their brain activity.

Last year research conducted in England discovered a similar scenario, but with shrimp instead of fish. Dr. Alex Ford from the University of Porthsmouth revealed anti-depressants in wastewater released into rivers and estuaries have probably already altered shrimp behavior making them more likely to be eaten by predators. So when Dr. Sauvé referenced the impact on the whole St. Lawrence river ecosystem, that is a very real possibility.

“We know that antidepressants have negative side effects on human beings, but we don’t know how exactly these chemicals are affecting the fish, and by extension, the Saint Lawrence River’s ecosystem. Nevertheless, we are seeing an impact on the river’s ecosystem, which should concern cities everywhere,” said Dr. Sébastien Sauvé. (Source: eurekaalert.org)

    I find this very interesting. I wonder if the shrimp were less fearful and that made them more likely to be killed. I hope at least they were happy in their last hours.

    One of the reasons YDV stands out amongst other vegan blogs- recognizing that veganism is more than just ‘what’s for dinner.’ Animal suffering comes in many forms resulting from human actions.
