‘“Almost all uses of land will entail some infringement on some other piece of land that is owned by someone else. So how can that ever be permitted? No story about freedom and property rights can ever justify the pollution of the air or the burning of fuels because those things affect the freedom and property rights of others. Those actions ultimately cause damage to surrounding property and people without getting any consent from those affected. They are the ethical equivalent – for honest libertarians – of punching someone in the face or breaking someone else’s window.”

So here we have a simple and coherent explanation of why libertarianism is so often associated with climate change denial and the playing down or dismissal of other environmental issues. It would be impossible for the owner of a power station, steel plant, quarry, farm or any large enterprise to obtain consent for all the trespasses he commits against other people’s property – including their bodies.’
