Mike McGrath (Feedback, September SR) repeats Malthus’s mistake in asserting that the cause of climate change is the number of people alive.
There is a direct link between increasing greenhouse gas emission and increasing industrial production due to the use of fossil fuels. However it is perfectly possible to decarbonise all production in a completely renewable economy which could support far more people without creating greenhouse gases in significant quantities.
Every one of us can be part of the solution; it is the politics of our rulers and the capitalist system that is the problem. We need system change to eliminate climate change.
