mair on page 27 you argue that a Malthusian future is the best way forward. In fact you described yourself as a Malthusian
This is how I understand this population theory - developed before the -industrial revolution,works.
Malthus theory argued that the population grows exponentially whilst food arithmetically. Of course the industrial revolution put paid to this argument, but there are still Neo-Malthusisms that feel his theory holds traction like yourself.
Malthus, when looking at the "problem" he saw as population growth, argued that we should restrict marriage between the poor and between people with "defects"
Malthus described a concept he used "positive checks". This describes processes such as war, starvation, disease etc as a positive phenomenon, as they help to stabilise the population to a more stabilise level.
This is no more than a very brief overview.
It is an extremely pessimistic and inhumane theory, attracting criticism from the whole spectrum of political thought.
