Most people don't like the idea of destroying the planet. But we can't save it by "like"ing articles on Facebook or tweeting about them. Unfortunately, most of us don't want to give up the second car and replace it with a bicycle, to give up long distance travels for work or holidays, to give up our tropical fruits in the middle of the winter, to give up eating too much red meat, etc. etc. etc. therefore almost certainly we're not going to leave a better planet to our children.
