Most of us assume glass is environmentally superior to plastic, but its footprint is generally far worse than recyclable plastics. Plastics can be tough to dispose of, but creating them is relatively environmentally friendly: The process is a byproduct of existing fossil fuel production (in the same way chicken nuggets find a use for every last scrap of the bird). And things are getting better, often invisibly: The modern beer can weighs one quarter what it did in the 1960s.
