Human beings have been smart enough to turn nature to their ends, generate vast wealth for themselves, and double their average life span. But are they smart enough to solve the problems of the 21st century?

Quotes from the same author

New information technologies-including email, the web, and computerized blast-faxes and phone calls-have fundamentally changed the landscape of political competition in modern democracies. They've done so in three ways: by dramatically boosting the access of individuals and special interests to politically potent information, by making it easier for such people to coordinate their activities and exert political power, and by greatly increasing the pace of events within our political systems.

Bitumen is junk energy. A joule, or unit of energy, invested in extracting and processing bitumen returns only four to six joules in the form of crude oil. In contrast, conventional oil production in North America returns about 15 joules. Because almost all of the input energy in tar sands production comes from fossil fuels, the process generates significantly more carbon dioxide than conventional oil production.
