One of the fun things about eating ice cream cones in the summer is munching down the cone itself. (The brown sugar cones were always my favorite).
Harvard professor David Edwards wants to extend that idea to other foods. He's invented a product called WikiCells, an edible packaging that mimics many of the properties of plastic without the environmental problems.
Most foods come in plastic packaging that is not only inedible, but ends up in landfills and the oceans. Most plastics never biodegrade; they just break down into smaller and smaller pieces. The results can be pretty devastating to sea animals and and other wildlife that eat the plastic, can't digest it and die of starvation when it accumulates in their stomachs.
