Unraveling the claims for (and against) green growth: Can the global economy grow indefinitely, decoupled from Earth’s limitations?

Economist Paul Krugman suggests that physical scientists have a false notion of economic growth. The economists differ on whether a continuous decoupling might allow economic expansion to go on indefinitely. It mentions relative decoupling, which refers to a decline in resource and absolute decoupling, which is an absolute fall in consumption.
