Merely hypotheses, nothing concrete. I don't know where do you actually pick up this stuff, but it isn't true, people are not happier or healthier than they used to be, food from my own garden, without pesticides or anything else chemical is the helathiest you can get, gm food chemical fertilizers they all are questionable quality, not to mention chemical fertilizers pollute water. I'm talking about today's world where you can afford this, however there are less and less places where you can "hide". If people want to smoke let them do it, but clean air is a much greater problem, yesterday I read in newspaper that Europeans live shorter for 2 years (that was great study) because of the polluted air, just how much than Americans live shorter? Yes, we do. For you who are successful and everything is as it should be (no health problems, no food problem no torturing on the work and etc...) there is no problem, but to those who are poorer than you, life is actually bitter. And all of these organization have proven to be a waste of money and time, not to mention WHO said, my god swine flu has the potential to kill millions of people, yeah right... And new diseases arrive from time to time, stress food pollution and etc., you cannot beat mortality that's one thing which is 100% sure, you die one way or another, you've been utopistic here. I fully support on what you're saying but the question remains will oil and gas industry actually allow this, I watched electric cars on Viasat explorer, than on hydrogen and etc. that's all ok, but we will see how the things will go. However, it must be noted that CO2 that is in the atmosphere will stay there for 200 years in the atmosphere before it gets absorbed in the ocean or something like that. Personally, I think there should be control growth of population, but science and technology do have practical limits despite what you say. Everything has limits, even science and technology. Which is worse to live lazy in polluted air, water, unemployment or live with fresh air, food, water and be free whatever you do? The only thing that should be kept are research in health and medicine. Cheers.
