Regular readers will know I’m a big, big fan of TED talks – I thrive on the optimism, insight and eloquence of the speakers. This one, by Johan Rockstrom, is another gem. I spend so much time reading, writing and discussing sustainability, it really takes something to grab my attention, but Rockstrom manages it. He quantifies all the major environmental pressures, shows how they almost all accelerated in the mid-50s, and demonstrates how many can simply be solved. I love his pronouncement that we are living in the most exciting decade in human existence as we try and ‘bend the curve’ back towards sustainability. Highly recommended.
