You're totally wrong about recycling pizza boxes. By saying so, millions will end up in landfills even though parts of them can be recycled. Instead of saying something stupid like "pizza boxes can't be recycled", my city prints a pamphlet with reasonable advice telling residents to tear off the top half of the box, where the logo is since that is usually not contaminated by food. So by telling people to throw out the whole box, there are probably lots of paper being discarded that otherwise could have been recycled. Before you say dumb things, please do research first. If my my city recycling program could think up the idea of recycling the lid of the box, why can't you? You probably have a lot of readers who follow your advice so next time, please try to avoid saying dumb things especially when they impact out environment.
