    • I do try to see the world through Pinker colored glasses, but sometimes it just seems like denial. I remember a bumper sticker from the cold war days that said "Just one nuclear bomb can ruin your whole day." It's great that technical progress has lowered the price of renewable energy to the point that is has become cheaper than fossil fuels, but the market alone is not going to force a transition fast enough to avert catastrophe. That will require government action, but so far the political will is lacking, especially in the US, but not only there.

      Here's the thing I only realized recently that has me so bummed out: climate change is very likely not going to eliminate human life on earth. Its indirect effects (mass migrations, wars, epidemics) will probably be more deadly than its direct effects (drought, fire, floods, famine, coastal erosion). The losses will be staggering, but the rich and political elites will survive and maybe even prosper. To be blunt, they don't care. I do hope that we can find a way to make it their problem too, but we haven't been very successful so far and time's just about up. Maybe two hundred years from now people will look back and wonder how we ever thought we could sustain a world population of more than eight billion people when 500 million was the optimal size for a post-industrial economy. Maybe, but I can't help but fear for the other seven and a half billion.

      My apologies for being such a downer and also to @LuckyLady for hijacking this thread. Regardless of the future of climate change, there are perfectly good ethical and health reasons to reduce meat consumption.
