One thing that people can do to reduce energy consumption, reduce C02 emissions, and who knows what other benefits, is to reduce their consumption of meat, particularly grain-fed beef. No cites immediately handy.
I noticed EasyJet has an option to make your flight carbon-neutral by paying an extra 2.18 Euros (at least on the flight I checked)

Methane being a much stronger greenhouse gas than CO2, per its "global warming potential" rating 23 times as high as CO2. Dallas' Vegetarian/Vegan organizations have been quite vocal about this. they've even suggested if cattle herding were eliminated, greenhouse gas emissions - including CO2 - would no longer be a problem. per US EPA's site <www.epa.gov/methane/sources.html> enteric fermentation, the way ruminant animals digest food, is number 3 on the list. but, the Hebrew Bible & the Koran both forbid consumption of animals which *aren't* ruminants. pork being the most well know of these forbidden meats. |

Still, consumption of ruminants is not mandatory, so anyone of any religion can participate in reducing grain-fed beef consumption. You're right about methane.
I think poultry is supposed to be a much more efficient food source in any event, and can be consumed by the faithful (if butchered according to religious laws).

You're right about methane. nothing i've ever read in scientific/agricultural material has ever said anything about different types of animal feed - be it grain, grass or anything else - having an effect on gas emissions from cattle. have you learned otherwise? <you've specifically said "grain-fed beef" in recent posts> Turkey farmers have certainly pushed their product for it's efficiency. but i've never heard any ads about poultry or pork as a tool against global warming. but, it seems logical that they would. in some ways, i hope demand doesn't go up too much. that might drive up prices for pork. (although, if demand for pork goes up, more of them will be raised for slaughter, moderating prices - in theory) i really like pork roast & wouldn't want it to become too dear! - d |

The problem with grain-fed beef is that it takes lots of petroleum fertilizer to grow the grain. If cattle is fed on existing grasslands, then the environmental and fuel impact is much lower. (Plus, the grain used to feed the cattle could conceivably be used to feed people, which isn't likely with grasslands.)

Also C02 controls the amount of watervapour in the atmosphere. More C02 in the air, means more watervapour in the air. An atmosphere with a lot of C02 can contain more watervapour, than an atmosphere with a lower level of C02 being present. visited my PhD friend & her husband (who is actually Dutch) this weekend. as she was the one who'd sent the GGWS link to me, i asked her about the issue above while i was helping get her house ready for the party. she said it's incorrect to say that more CO2 has a cause & effect relationship with more water vapor in the air. she said CO2 & H2O levels are independent of each other. but, higher temperatures in the atmosphere makes it contain more CO2, and higher temps also makes the air able to hold more water vapor. one does not cause the other but both are caused by the same condition. or, words to that effect.

I got the information from the KNMI website ( www.knmi.nl/klimaatdesk/broeikaseffect.html), which is in Dutch. KNMI is the Dutch weather instutute. . I presume it is always possible that I have made a translation error, but they claim exactly what I've wrote. (last question, point2) |
