machtfaktor erde. great two-part documentary on future problems through climate change, including water, resource wars, territorial conflicts, land grabbing, etc. this should also be subtitled in english; realizing how the world is experiencing changes and preparing for more should be a major call to action. climate change will be the underlying master challenge of the next century, and it was caused by our ‘economic’ activities that led us to exploit our planet with brutal force. even the IEA acknowledges that ’the door is closing’.
