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.
Plastic recycling is mostly B.S., it's difficult and so energy intensive that it's usually better for the environment to landfill the old plastic and make new stuff. Metal and paper recycling is very environmentally sound though.
Hey, I've recently been marathoning this show. I'd say your description is as dishonest as you accuse penn and teller of being.
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.
