cup of tea: I don't think only respect several thousand of ethical groups interest and let millions of others lost chance to have electricity and development is fair at all. You can always find someone disagree on some big project, as long as it has more than 10 people involved. With developed country had the highest rate of utilization of all the nature resources like hydro, thermal, fussile, and build most of road/rail per person, why they are so enthusiastic to blame poor people to develop anything to make them closer to the developed country? Do they think it is respectful to force poor people keeps in poverty? And don't provide any alternatives? Don't tell me solar or wind is the solution. They have big eco consequences too. And much expensive for init cost. And much shorter life span (20 years at the most vs 100 years for hydrodam ). US and Canada utilized 60% plus of tapible hydropower. While China is only sub 30%. And most of developing countries less than 10%.
