Poison in the Arctic and the human cost of 'clean' energy

(Harvard University) Harvard research suggests that high levels of methylmercury, a potent neurotoxin, in Arctic life are a byproduct of global warming and the melting of sea-ice in Arctic and sub-Arctic regions. To mitigate global warming, many governments are turning to hydroelectric power but this research also suggests that flooding for hydroelectric development will put even more methylmercury into ecosystems than climate change.
