> There is evidence for global warming, though there's considerable reason to believe this is simply part of a natural cycle. There is some evidence that humans may contribute at least a bit to the change (though many sources suggest that human pollution is insignificant compared with forest fires, volcanos, etc.).
This is underhanded, weasel-word denialism. "Many sources suggest" my ass... Let's not give any credibility to this kind of bullshit.
Great magicians, but dishonest skeptics.
Glass too.
In that episode, they mainly point to paper and plastic recyclables as being net societal losses in 2003 when the episode was filmed. They only talk about metal and glass briefly, because it's pretty apparent that it is efficient to recycle metal and glass.
For what it's worth I don't actually think you are being dishonest, just hyperbolic.
The show pretends to be just about calling out "bullshit", but sprinkles in a lot of politics and opinions.
