Not to dwell on the negative today, but we have another problem. According to a recent article published by the New York Times, a new study has linked Arctic melting with the release of POPs (persistent organic pollutants) into the atmosphere. Remember all of those harmful chemicals we banned 10 years ago? Well, they've come back to haunt us! Potentially released POPs include banned pesticides, such as DTD, lindane, and chlordane, all of which are known to have detrimental effects on people and the environment, Treehugger reports.
But why does it matter if toxins are released in some distant Arctic realm? Unfortunately, POPs are known to travel briskly in air and water currents and can easily build up in both human and animal body fat. Today, a rise in certain POPs has been detected by air monitoring stations in Canada and Norway, indicating remobilization is already underway.
Although it may be under the shadow of other, more serious, climate change-related problems, the release of toxins associated with Arctic melting is yet another reason why we must advocate for reduced greenhouse gas emissions. If we can decelerate Arctic melting, we will be saving more than just polar bears.
