(Those of us who are able, that is.)
Drink less non-human animal milk, too. (Unless you need what’s in it, like calcium, and can’t find it anywhere else.)
See, factory farming on land – cows, pigs, chickens, etc. – may be America’s Number One source of Greenhouse Gases. Factory farming in water – many seafoods – is a very bad scene for other reasons: diseases, unhygienic, pollution, etc. But demand for flesh-foods of all kinds is going through the roof, with big parts of the Third World (China, India, etc.) now ‘coming online’ in that regard. And many natural fisheries are already in danger of being ‘fished out.’ Hence, we need to eat less of all flesh foods.
But substituting plant foods is problematic because the recent “Green Revolution” was mainly wrought by petro-fertilizers, and they’re going the way of the dinosaurs, so more plants is not an option. And I think letting GMOs out into the planetary gene pool – eg, to increase crop yields or selected nutrients that way – is way too big a threat without knowing the long-term and even very-long-term consequences; we’ve only got one planet folks! (For now.)* And increasing arable land by burning forest adds carbon dioxide and other Greenhouse Gases to the atmosphere, and takes away trees that help remove these gases from the atmosphere.
Hence, eat less of everything if we can.
Obviously people with eating disorders who don’t eat enough, or with malnutrition or simply true hunger (vs. psychologically-induced pseudo-hunger) or certain health problems, or perhaps who are elderly and/or frail, etc., shouldn’t worry about this. But the rest of us, especially the 2/3 of Americans who are overweight (Canadians and Brits are up there too), could use this for extra motivation, if overeating is a problem.
Also, let’s not stop partying, people! But is every meal a party? every supper? Not where I come from!!!
And let’s not cold-turkey it and drive ourselves crazy and set ourselves up for failure. Perhaps a good program to start with/build up to (in the beginning) is the Orthodox Church’s “fasting” schedule. (That’s “abstaining,” for you Catholics and High Church Protestants.) Most Wednesdays and Fridays of the year, the 40 days before Christmas, the 40 days before Holy Week, Holy Week itself, the period between Pentecost and the Feast of Saints Peter and Paul (June 29), the first half of August, and a few other “fast” days throughout the year. (Old Calendar or New Calendar.) Before I became Orthodox, but was considering it, I was told I shouldn’t try to fast; spiritually it wasn’t a good idea. But I see no reason why people not currently considering Orthodoxy couldn’t adopt some or all of its fasting practices as a simple eating program. Like I’ve said, Orthodox “ascesis” may turn out to be a great idea for the whole human race and the earth! Fortunately or unfortunately, the decentralized structure of the Orthodox Church means there is not in every sense a uniform practice of fasting. I could point you to websites that might seem to conflict, or in going overboard in describing the strictest forms of the fast may discourage and demoralize. What you might want to do is consult an Orthodox parish near you; I’m sure they’d be glad to help!
