Do you live near any place that's been affected by pollution, and how is it affecting your part of the world?
Personally, I live near the Baltic sea; which has been hit pretty hard. Water is no longer clear in the summer due to excessive algae blooming, this also makes bathing in the water unhealthy, and the poisons in the water makes fish dangerous to eat in larger quantities (especially if you're pregnant). Also, a large portion of the sea has become a dead zone, where no fish or plants can live.
So, how about you? You've been affected? Also, don't let this turn into a heated discussion about Global Warming, lest Bean Bandit will descend from the skies in his chariot and shoot thunder and lightning from his hammer closethreadnir.
