Plastics - it's gotten this bad

While researching for an ocean writing class I'll be teaching at 826 Valencia I came across these factoids on science.howstuffworks.com. Enough to make you rethink your bottled water choices:

"Plastic constitutes 90 percent of all trash floating in the world's oceans [source: LA Times]. The United Nations Environment Program estimated in 2006 that every square mile of ocean hosts 46,000 pieces of floating plastic [source: UN Environment Program]. In some areas, the amount of plastic outweighs the amount of plankton by a ratio of six to one. Of the more than 200 billion pounds of plastic the world produces each year, about 10 percent ends up in the ocean [source: Greenpeace]. Seventy percent of that eventually sinks, damaging life on the ocean floor [source: Greenpeace]. The rest floats; much of it ends up in gyres and the massive garbage patches that form there, with some plastic eventually washing up on a distant shore."
