Two Consequences of Malthusian Theories
According to Malthusian theories, elementary science implies that unrestricted reproduction is irresponsible. In other words, the widespread dissemination of Malthusian theories will suppress the number of people raised to believe in both what is called elementary science and responsible behavior. That, in turn, has two effects: 1) People who believe in what is called elementary science will tend to be more irresponsible. 2) People who are trying to be responsible will be skeptical of science.
This might be an explanation for both environmentalist wackos and creationists.
For the record, I hold that overpopulation overshoot is a common problem in animals but we're plants.
