Object to litter? You right-wing monster!
We're constantly bombarded with hectoring calls to do more to protect the environment, but most of these suggestions simply involve gesture politics - like turning off the lights for an hour during Earth Day. It won't make nay difference to the planet, but you'll feel all nice and virtuous and can tell people that you're doing your bit.
That's why most of us tune out whenever we hear someone lecture us about the evil nature of cars or certain light bulbs.
But we can control the environment around us - which brings me to the annual debate about litter.
