This article talks about an innovative bottle that can be eaten. But, it also discusses the extent of the plastic bottle problem in today’s oceans. About 1.5 million barrels of crude oil are used annually to manufacture plastic bottles, according to a 2007 resolution by the U.S. Conference of Mayors. They often end up in the ocean; there are roughly more than 46,000 pieces of floating plastic trash for every square mile, according to a report by the United Nations. http://www.smithsonianmag.com/innovation/Heres-A-Water-Bottle-You-Can-Actually-Eat-180951185/#Vd0tPXD0D3GMH7Lb.99
