Natural disasters have a nasty habit of compounding previous, semi-manageable problems. We saw this with the Fukushima nuclear meltdown in Japan following a massive tsunami. Now we’re seeing it again, this time with Hurricane Maria in Puerto Rico. On top of food and medical shortages, experts are worried about several environmental issues exacerbated by the storm. While many of these issues — from poor industrial quality control to a general lack of clean, contained drinking water — already plagued Puerto Rico, the devastation of Maria has complicated matters. In many cases, it has made them a great deal worse.
