Maybe the question to population deniers should be framed as:
What upper and lower bounds do you place on the hard limits of how many humans the planet can support indefinitely?
What upper and lower bounds do you place on the rate at which technological progress pushes the practically achievable limits toward the hard limits above?
What upper and lower bounds on future world population levels given that the current number is 7 billion?
From this we can then derive at least a self-consistent probability that overpopulation deniers should assign to Malthusian Crunch.
Yes, exactly.
