From: Secret Underground Lair
I harbor some pretty cold hearted ideas about how sheer population size combined with ever-increasing standards of living are the ultimate cause of most human suffering, including natural disasters like Katrina or this Japan catastrophe. While it seems a bit callous to say so right after one of these unsafe areas has been hammered by a natural disaster, it deserved to be pointed out: not all areas of Earth are equally suited for human inhabitation. Many areas like large chunks of California, Hawaii, Japan, etc., are quite prone to Earthquakes. There are areas that are vulnerable to volcanoes. Various areas in the American midwest are vulnerable to tornadoes and flooding. Coastal areas are always subject to the vagaries of the sea. Mountainous areas suffer landslides and avalanches. And then of course there are droughts, which can occur pretty much anywhere, but certainly seem to favor certain areas more than others. If you conservatively estimated the sum total of areas on Earth where it was "safe" to build a nuclear plant, let alone safe for people to live, there probably wouldn't be enough room for a billion of us. Moving to areas that are not subject to certain natural disasters is an option for some of us, but for those who stay, periodic catastrophes are just going to happen, and it is foolish to think that they won't. From that standpoint, building nuclear powerplants on that particular chunk of Japan (if not the whole island? I don't know its geology that well) is one reflection of the poor decision making which large population demands and the normalization of those demands exert.
I'm not saying I'm glad anyone suffers, and I'm certainly not suggesting something like "a few more dead people is good because it reduces the population size." But these catastrophes are a good time to be reminded about the real, ultimate causes of such suffering, and how, in the long turn, we humans can avoid such needless suffering if we would transform our societal values relating to families and reproduction. If only those who really have a calling for parenting became parents, we could conceivably in 500 years have this planet back into something like a "normal' state.
