Several studies have been published on the question of GHG emissions from hydropower reservoirs. Reservoirs, like natural lakes, emit a certain quantity of GHGs due to decomposing vegetation; however, the scale of these emissions has been shown to be highly variable and more research on a case-by-case basis is required. In a study of a hydropower dam in Brazil, emissions were very high, but in the case of reservoirs studied in boreal regions, Canada for instance, results have shown that emissions are significantly lower than those produced by the combustion of fossil-fuels to generate electricity.
In any case, clearing the vegetation in the area to be flooded can reduce emissions. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
