Bjorn Lomborg : (2) " If we invest in researching and developing energy technology, we’ll do some real good in the long run, rather than just making ourselves feel good today. But climate change is not the only challenge of the 21st century, and for many other global problems we have low-cost, durable solutions. " - Bjorn Lomborg " When thinking about the future, it is fashionable to be pessimistic. Yet the evidence unequivocally belies such pessimism. Over the past centuries, humanity’s lot has improved dramatically – in the developed world, where it is rather obvious, but also in the developing world, where life expectancy has more than doubled in the past 100 years.
