Manure to Carbon Dioxide to Zero Emissions
The ever-so-eloquent Wade Davis, the anthropologist, ethnobotanist, filmmaker, and National Geographic Explorer-in-Residence,
is in Copenhagen this week, roaming the streets, speaking with experts, and taking in the exhibits on display throughout the city while the United Nations COP15 meetings on climate change are underway. He’s been putting together a fabulous blog of video and interview clips called the Journey to Zero project, and we had to share his convincing argument for why we need to work toward a zero-emissions form of transportation.
What if, Davis reasons, instead of releasing over 17,000 pounds of C02 gas a year, cars spat out bricks of carbon instead? It’d be a tangible presence on our streets, not unlike manure was at the turn of the century, when horses dropped over 2.5 million pounds of manure in the streets of New York city each day.
