UBC Professor William Rees argues that climate change is the largest collective threat humankind has ever faced as we are now a global culture. Individual choices to reduce their eco-footprint will not have a huge effect. Sustainability is not about acting alone, but is a collective enterprise so we must make our cities so it is possible for our citizens to live a sustainable life. We are all on the Titanic together.
