A restraint of liberty
"It is not just that we are free to kill other people; market freedom constrains us to do so. The economy is so organised as to make it impossible to do the right thing. If your village isn't served by public transport and there is nowhere safe to cycle, you have, for all the talk of freedom to drive, no choice. If the superstores have shut down all the small shops, you must give your money to a company whose purchasing and distribution networks look like a plan for maximum enviromental impact.
So we are encouraged by the market and left free by the law to inflict the most grievous harm that any group of people has ever inflicted on any other. There are several good reasons for supposing that climate change, within the course of this century, will throw the world into food deficit...
...Already, with a food surplus, some 800 million people on earth are permanently malnourished. With a net food deficit, this figure could rise into the billions. We will be responsible for this. By the time we reach the end of our lives, every one of us, however kind and mild and well-meaning we might be, will have been responsible for the equivalent, in terms of human suffering, of a medium-sized act of terrorism."
George Monbiot
