I agree with most of what he said. Overpopulation is causing problems, especially with food shortages. The U.N. is really concerned with this.
I know I'll sound horrible saying this, but we need to respect nature a lot more. Desert areas where these is no food, or the potential to grow enough food... those places aren't supposed to be thriving with humans. The process of these areas turning to desert happened slow enough that under normal circumstances, those people should have migrated to other areas, or died off. What we've decided to do is maintain the suffering of those people over generations at the expense of everyone else on the planet.
As for Global Warming, that's all about profit. Those Carbon Credits Gore goes on about paying... those payments go back to his own company. There's an entire industry being built up around this hype. The solution to too much Co2 is simply more trees. We were warned in the 80's about destroying the rainforest, but those same companies are now saying there's too much Co2... right. High levels of Co2 have not shown to be associated with warming trends in history, but high levels of solar activity have... and we're having that now and every planet is being affected, even the ones we aren't on.
We do spend entirely too much on the military, and the insurgents are a kind of patriot. I'm not saying I support them, but if I were in their shoes, I'd be fighting against a group of invaders from a foreign country as well.
We're also being told that a border fence is an impractical solution for securing our borders. Yet we're spending our tax dollars on a border fence for Egypt... coincidentally the exact SAME border fence Israel wanted to build back in September. While the media skips that fact over here, you can bet it's making a whole lot of people over there very angry.
All of this needs to stop. The money we spend on the military and all these bullshit terrorism programs are hurting us. Our economy is tanking, the US has record numbers of idiots graduating high school, and we're expelling second grade students for sexual harassment. All of this stuff has gone WAY too far, and while most people don't feel the effects yet, by the time they do, there won't be anything left as far as freedom goes. Already, the US has more prisoners per capita than anyone else... and we're spreading Democracy and Freedom around the world?
