What could possibly be ethical about flying? There are moments when we justify
travel by plane, for work or family. The latter the writer George Monbiot
calls 'love miles'. There are often better ways of expressing love, and ethical
living does require sacrifice, some of those sacrifices are hard to bear.
If you are planning a trip by plane, a website to read is http://www.flightpledge.org.uk/,
where you can Pledge not to travel by plane (you even get
a certificate to remind yourself). This site has links to many others, including
campaign sites to stop the madness of airport expansion.
Or sign the pledge on this site, inspired by Druid author and teacher, Nicholas Mann: Page of Pledges
