And belching, <but this, mostly by cows.
Anyway, it would be best not contribute to greenhouse gas emissions, by ingesting beans, lentils, pork, artichokes, asparagus, broccoli, brussels sprouts, cabbage, cauliflower, cucumbers, green peppers, onions, peas, radishes, raw potatoes (who eats them raw except perhaps Ebenezer Scrooge), apricots, bananas, melons, peaches, pears, prunes, raw apples, wheat, brans, eggs, certain sugar substitutes, milk and dairy products if you are lactose impaired, beer, wine...wait, they're gas forming, too?
I'm sure there are more as it goes from individual to individual, and no matter what benefits they may have, we must forgo them!
So, in short, do your fart, I mean, part and stop expelling!
Give a hoot, don't pollute, have a heart, don't fart! That's my campaign slogan.
Vegans take note, eat cows instead of beans!
