In March, Jeffrey Sachs published his latest book Common Wealth: Economics for a Crowded Planet – an urgent plea for societies across the globe to reduce and better manage their impact on the earth’s ecosystems if we want to survive and prosper in an ever more crowded world.
As Sachs warns, continuing ‘business as usual’ will make life on our planet increasingly unsustainable. Air pollution and global warming present the biggest risks. But as humans have come to use almost any natural resource intensively, there are also major risks related to the availability of water and of fertile top-soil. At the same time, Sachs argues that we have the technical tools and the economic means to save the planet and to accommodate a rising global population – as well as increasing global wealth and rising consumption in today’s poorer countries.
