Ask The Bad Astronomer

Astronomer, author, columnist, and successful populizer of science Phil Plait, perhaps best known as The Bad Astronomer, is a regular sight on Slashdot for his unusual ability to find lucid explanations of esoteric scientific claims and controversies. Phil has graciously agreed to answer Slashdot readers' questions, so ask him below about space, science, debunking conspiracy claims, and anything else that makes sense. Asking more than one question is fine (and encouraged!), but please separate unrelated questions into separate posts, lest your questions be moderated down.

Light pollution

[Frenzied Apathy]

There are a large number of light pollution articles to be found on the Sky and Telescope website. We amateur astronomers are keenly aware that light pollution isn't just about being able to see more stars from our backyard. Yet, when I mention the subject to friends, family, co-workers, etc, I often get a blank stare. "What's 'light pollution'?" What do you think can/should be done to improve widespread public awareness of light pollution and its effects?

What do you think is the bigger threat?

[UberOogie]

Given your unique position, I'd like to know your answer to this question:

What do you think is the currently a bigger threat to legitimate science:
- The growing wave of anti-intellectualism and anti-science that seemingly rejects science outright on certain issues
- Or the growing wave of pseudo-science that undercuts science by adopting the trappings of science but none of its procedures?

Thank you for your time.
