Fasting and the environment

Most religions have fasting disciplines. Christians have traditionally fasted on Wednesdays and Fridays, abstaining from meat and other animal products.

Now there have been proposals for new secular fasts, on Mondays or Thursdays -- for more information and links see here: Notes from underground: Meat-free Monday?

But perhaps there is a need for a revival of the fasting disciplines of the various faith communities.

It would be good if people could explain briefly what their fasting disciplines are in comments below.

For Orthodox Christians it is abstention from meat and animal produce (eggs, cheese, butter etc) on Wednesdays and Fridays, in Advent and Lent, and from today until 29 June, and the first fortnight of August.
