There is a new kind of paper called seed paper, which is 100% biodegradable and embedded with seeds! So the idea is simple: make cups out of seed paper, then allow users to throw away their cups in gardens or landfills, creating a bunch of new plants! This idea cuts down on global warming greenhouse gases and reduces landfill waste. So, in a nutshell: Problem solved. Humanity saved.  Ozone gases depleted.  All for the price of a cup of coffee.
