There is a debate as long-running as climate change itself: can capitalism, with its demand for endless growth, be sustained on a planet with finite bounds and limited resources? Freemarketeers say yes. For them, the issue is not capitalism per se but an economic model that does not factor in the true cost of emissions. As a result, we the people and the planet are subsidising industries that pollute for free. The counterargument is based on simple intuition: How on earth can capitalism, the unstoppable force be contained inside the inelastic object? This has never received a convincing reply.
