To Arundhati Roy, Big Dams on rivers are terrible: Nations put them in to control their people:
Big Dams are to a nation’s ‘development’ what nuclear bombs are to its military arsenal. They’re both weapons of mass destruction . . . They represent the severing of the link, not just the link — the understanding — between human beings and the planet they live on. They scramble the intelligence that connects eggs to hens, milk to cows, food to forests, water to rivers, air to life and the earth to human existence.
