We often hear people being criticized for driving “gasguzzling” vehicles or eating at fast-food restaurants that dispense millions of sacks, wrappers, cups, and other disposable products, some of which eventually litter the nation’s roadways and dump sites.

Or are environmental problems beyond our control because they are caused by natural causes or decisions of large corporations and governmental agencies over which we have no control?
