Here is my attempt, let's see how well I retained the information from the video:
air pollution: private property problem. If private property were actually enforced and justice were not actually a monopoly controlled by guns and violence, then nobody would be allowed to pollute the air.
paper vs plastic: if you actually had to pay for the disposal of the plastic instead of relying on the government to pick up your trash, then you would be paying a lot more to dispose of plastic bags instead of paper bags (assuming what environmental wackos say is actually true).
overpopulation: If everyone on the planet had a middle class home with a yard, you could fit the entire population in the state of texas. If you crammed every human being into a cube, the cube would only have to be 1 mile squared. The midwest is virtually unpopulated.
forests: can't remember what he said.
running out of resources: If prices are not manipulated by government, then when resources are low, they become expensive, thus less people buy them, and also more people look for more of that resource.
buying local: this is just common sense, most of what you buy is made 10,000 miles away. Mozart, The Beatles, most really good stuff is not local.
environmental racism: he talked about how poor people are usually in high polluted areas and the reasons for this is because either companies take advantage of poor people who can't sue them, or else companies homestead some land and the value of the surrounding land becomes lower and thus more affordable for poor people. The former is bad, and the latter is good because you want poor people to be able to afford land.
I forget exactly what he said about the other stuff. And I'm sure I butchered what he said in the video pretty good because I have a really crappy memory. So you should really just watch the video instead of relying on my poor memory. It's usually pretty difficult to go from learning something to teaching something.
