The whole landfill thing has always prayed on human's inability to get to bigger picture. They see a dump and somehow think it'll take over as time goes by.
Dig a hole, put rubbish in it, push dirt on top 50 years later and you get a nice park.
Don't think it's safe for humans on top, even better a guaranteed wildlife refuge.
Really? And what is the primary goal of recycling glass then?
Fair notice: if you say conservation I'm going to laugh at you.
