What we do to trees

I just read this on a flyer advertising a protest downtown:

Catalogue retailers send out 20 billion catalogues a year, and almost none of the paper contains any recycled content. Instead, over 8 million tonnes of trees a year go into catalogues alone - which means 8 million tonnes of trees are going from forests to the landfill, with a short appearance as junk mail in between. By increasing recycled content, cataloguers could greatly decrease their negative environmental impact, cut air and water pollution, and decrease the amount of paper filling up landfills.

I don't know what anybody else is supposed to do though, except maybe gasp.
