All those save the planet signs and especially the energy of young people engaged in this issue are inspiring but the reality is that the planet would be fine without us: it is the humans that need the saving energy. I’ve often said that the human species is in its adolescence: full of both creative and destructive potential. This next decade will clearly bring a series of defining moments as to which path we choose: survival vs suicide. And the quality of life in terms of future survival is very much dependent on our current-day choices. How wide the divide between climate science and our collective ability to take action!
