We don’t need to do anything fancy to check climate change. Limit the number of human beings, and the Earth’s health will be restored very quickly. Nothing else is needed.
The biggest contributor to climate change, rather the only contributor to climate change is human beings and their consumption, quantity multiplied by consumption per head; and both go together. The very occurrence of the quantity is because of a desire to consume.
So, it is not quantity multiplied by consumption; it is quantity square, quantity multiplied by itself. Limit the quantity and everything will be alright, quite simply, quite obviously. But nobody ever talks of this obvious step.
