Capitalism rules the world now. Even countries we once thought of as committed to communism now allow at least some semblance of a free-market economy.
And that creates some problems for the planet, since capitalism can be tough on the environment.
Several economists have pointed this out; now a pair of college professors make a more pointed case in A History of the World in Seven Cheap Things: A Guide to Capitalism, Nature, and the Future of the Planet.
Raj Patel and Jason Moore are not using "cheap" in the good sense--it's not about low prices. They explain their argument in a joint visit to The Exchange.
