[...] Agricultural data from 38,700 farms plus details of processing and retailing in 119 countries show wide differences in environmental impacts — from greenhouse gas emissions to water used — even between producers of the same product, says environmental scientist Joseph Poore of the University of Oxford. The amount of climate-warming gases released in the making of a pint of beer, for example, can more than double under high-impact production scenarios. For dairy and beef cattle combined, high-impact providers released about 12 times as many greenhouse gases as low-impact producers, Poore and colleague Thomas Nemecek report in the June 1 Science.
[...] The greatest changes in the effect of a person’s diet on the planet, however, would still come from choosing certain kinds of food over others. On average, producing 100 grams of protein from beef leads to the release of 50 kilograms of greenhouse gas emissions, which the researchers calculated as a carbon-dioxide equivalent. By comparison, 100 grams of protein from cheese releases 11 kg in production, from poultry 5.7 kg and from tofu 2 kg.
[...] Producing food overall accounts for 26 percent of global climate-warming emissions, and takes up about 43 percent of the land that’s not desert or covered in ice, the researchers found. Out of the total carbon footprint from food, 57 percent comes from field agriculture, livestock and farmed fish. Clearing land for agriculture accounts for 24 percent and transporting food accounts for another 6 percent.

Is that they disregard the fact that we are supposed to eat meat. As far as I am concerned though, we eat *too much* of it. and there are alternatives that could helps us reduce our meat intake greatly (I mean beef as well as others...). But giving up on meat altogether would, in my opinion, be an issue and lead to other problems (deficiencies because people are not informed etc.).
I am no tree hugger but the waste of life that happens when you throw away or discard uneaten portions of meat bothers me a lot too. If something was raised, fed, cared for (to some extent), slaughtered, prepared, sold, cooked etc. and ends up not being eaten, then it's a huge waste. Whenever I read these stories I think about the meat portions in North American restaurants: "for an extra $3 you can double the size of the steak!". Even if you don't end up wasting it and take the leftovers home, you still end up eating too much meat.
Diversity and moderation would, in my opinion, work much better than messages about switching diets entirely. Then you can buy good meat that is actually tasty and enjoy it fully.
Just my two cents...

Absolutely. However, what baffles me most, is that each and every message of the type "we should reduce meat consumption, overall" is perceived as "everybody shall stop eating meat, entirely", invariably. Granted, the article mentions "switching", rather than "shifting" to a plant-based diet, so that may not be an ideal choice of words. Also granted, there is no shortage of very vocal activists who will advocate just that. But I definitely cannot shake the feeling that a lot of people apply an all-or-nothing reading to any message about the downsides of meat consumption, actively. It's just so convenient: Stretch the message so much that it is easy to refute, then conclude that it is obviously wrong from the start. No need to even think about your personal contribution, then.
