This data was from a British government-sponsored study, with media reference made by Jonathan Leake in the Sunday Times of London. The reason given for the higher CO2 footprint was that lambs burp (and probably farts to release methane and other greenhouse gases like you, me and the cows) a lot.
Problem was the study was advising to give up lamb roasts to save the planet, not beef. Sure, lamb roasts may be more popular in Britain than in North America, but I highly doubt it is more consumed than beef in either place. If anything, find a way to reduce cow farting and burping, possibly by altering their diets a little. Should be quite possible given you and I both know that if we don’t eat certain things, we don’t fart and burp nearly as much as other things we do eat.
Besides, even if sheep gave off more greenhouse gases than cows, I think most people would agree with me McDonald’s and other beef burgers generally make people fart more than with lamb roast, especially given what else you eat with fast food. We definitely make up for what the cows fart and burp less than the sheep.
Who does those studies and draws those kinds of conclusions???
Mary had a little lamb,
Which burped and farted lots,
Everywhere that Mary went,
She sure smelled like she rots!

Space junk debris field around Earth, from Fast Company Magazine, courtesy of the US Space Surveillance Network
Space… the final frontier… not for exploration but for polluting.
On Tuesday, at about 1700 GMT (12:00 p.m. EST), two satellites collided by accident in orbit about 500 miles (790 km) over Siberia. The collision was foreseen to be likely, but one that was not avoidable because the culprit was a Russian satellite launched in 1993 weighing a ton, believed to be nonfunctioning and out of control. The other was a half-ton (1235 lbs) Iridium commercial satellite, which was launched in 1997.
The immediate space above the Earth has become cluttered enough to allow this sort of thing to happen now, apparently, and it will only become more common in the future. With at least 18,000 pieces of space junk bigger than 4-inches tracked by the U.S. Space Surveillance Network (see photo), all whirling at tens of miles per hour, our immediate space is become a dangerous place to be! Even in the vast expanse that is space, we’ve managed to pollute it so badly it’s becoming a hazard. Where will we go pollute now?
The collision created another 500-600 pieces of debris, by the way. And it should also be noted that not unlike Earth, China is responsible for more than its fair share of pollution. China might not be thought of as a space power yet like the Americans and Russians are and have been over the years, but they’ve got as much junk up there as anybody.
The linked sources below have much more information on space junk, distributions, sources of the junk and so on, if you were interested. There are hopes, I should end with, for systems to help self-remove future space technology as they become dated. The Fast Company link below has some details. It’s a good start to help alleviate this problem before it gets more out of hand. Let’s just hope all the space players think responsibly to do it.

The formula seems to be when a country devotes 40% of its renewable water resources or more to irrigation, it starts to face water allocation issues. It must import food, especially water intense crop.
Saudi Arabia, China and South Korea are among these countries. They are starting to lease land in Africa to grow food.
China is acquiring agricultural land in Southern Africa.
Daewoo Logistic is looking to lease land in Madagascar.
More countries in South Asia and the Gulf are considering similar moves because all countries in South Asia are projected to be at this point by 2030, among a projected 35 countries by then. Middle East countries are expected to hit 58% of its renewable water resources to irrigation by 2030.
