Taltamir, I think you are onto something, but well, see what you think. I do not think genocide will have a meaningful impact on AGW as the ones being murdered are not the ones with huge global footprints. I believe that genocide is being used for the industrialized nations to conserve resources for food, medical care and energy production for those they consider more deserving.
“The day the earth stood still” was and still is a classic movie for me anyway. The remake, well I watched it simply because I wanted to see what modern film making could do. You could measure the mood of the country in 1951 to figure motives out, but the truth is that both movies were tailored after a book written in October of 1940 by Harry Bates entitled "Farewell to the Master. I think the only things to be picked out in this kind of a movie are the prejudices of the times as the storyline came from the 30’s and 40’s. I do not feel like going that far back myself. This was a time for Sci-Fi and several movies came out that year. But many want to use the prejudices of our own times to somehow figure out their motives … same lame reasoning is almost always used whenever we venture back in time, go figure.
