Why we must give up flying

Nothing, but nothing since the last Ice Age has posed a bigger threat to mankind. Some scientists think that we may have 10 years to make a sharp reduction in carbon-dioxide emissions. Other s think it is already too late, and that mankind will be lucky to last until the end of the century. My own culpability in this man made mess is considerable. For the best part of 20 years, I worked as a travel writer, and although nearly all the books I wrote were based on journeys by bicycle or on foot, I often flew to my chosen country. From the earliest days of the global-warming issue, flying has been implicated as a significant contributor to atmospheric overload.
