I usually Tvo Oprah Winfrey show and watch it later when I have time. Sometimes I might be days behind. This last episode I just watch was the Earth Day. This has changed my mind on using plastic bags for sure. I just switch to the cloth bags to do my grocery shopping in. I think this is a concern for the future. Here is info on Oprah's website THE GREAT PACIFIC GARBAGE PATCH
and you can find several information on the famous youtube. Niteline Pacific Garbage Dump If you seen this are you concerned? I was surprised!
