The new year 2012 brings new expectations and changes. The city of San Jose, for example, enacted a ban on plastic bags at grocery stores and other retailer check outs. In response, residents and approximately 5,000 retailers are all adjusting to this new experience, making San Jose the largest U.S. city to ban plastic carry-out bags. Apparently San Jose, along with many other cities, is determined to avoid perpetuating the history of urban area pollution. The environmental destruction has plagued so many places, including the River Thames in London which was declared “biologically dead” in the 1950s.
