The great population debate: too many carbon footprints?

I've watched about half of this video so far. It's around an hour. I think it's important for Catholics to watch who take their faith seriously, even though it's not a religious video. The video concerns the idea of overpopulation, and there is a debate between two men in their respective fields.

The first man, in my opinion, is rather annoying. He represents a group which believes people are having too many children and that the Earth is overpopulated. He believes in using contraception to reduce the population of the planet. But the thing that struck me about him is his enormous arrogance. He speaks about those who do not believe in overpopulation as if they are very stupid. He talks down to anyone who disagrees with him. In fact, in one part he refers to "rednecks". This all comes back to a form of elitism, where certain people feel they must tell others what to do and use the government to back them up, or else those people will not know. He thinks he can plan out the whole planet.

And something else he says is actually kind of shocking. Without any prompting whatsoever, he mocks the idea of salvation and God. I have no idea why he tried to bring religion into the debate, but he does. Also, he seems extremely critical of the pope.

Feel free to skip the first guy. He does seem rather intelligent, but you can strongly sense what the second man calls "misanthropy". Basically, the population control people seem to view human beings as viruses of the Earth.

Anyway, the second guy who speaks does present some very good arguments. He is great to listen and will provide ammo to anyone debating against the myth of overpopulation.
