It's ridiculous to worry about protecting america's national parks against pollution and overuse when innocent people are being endangered by terrorists.

I don't agree with this statement. the two things should not have been put in a chart. Both are important, one on a short-term, the other on a long term. Not worrying about pollution and environment would mean the collapsing of our ecosystem, with a great danger to our entire species and with a number of effect over our biosphere.
