Discuss the impact of plastic waste on the environment and what can be done to address this issue.
It is yet another wake up call. I live in California, 40 or so miles from the beach, but we all know the storm drains go to the ocean. After a big rain, the harbors get filled with floating plastic bags and styrofoam cups, which eventually sink and drift away.  But all this crap from 7 billion people, and especially those of us at the coasts, isn't just going to biodegrade away.  We just banned plastic bags here in California for grocery purchases. I voted against the State Proposition because I thought it was stupid, but now have changed my mind. We use way less bags; no surprise there.  It is a hassle to bring a bag to the store, but we get by, and sometimes I use no bag at all.  There are ways our civilization can change to solve or at least reduce these problems.
