Research into the environmental impact of animal-based foods has concluded that beef has the greatest impact by a large margin (Full text [pdf]).

When the numbers were in, including those for the environmental costs of different kinds of feed (pasture, roughage such as hay, and concentrates such as corn), the team developed equations that yielded values for the environmental cost per calorie and then per unit of protein, for each food.

The calculations showed that the biggest culprit, by far, is beef. That was no surprise, say Milo and Shepon. The surprise was in the size of the gap: In total, eating beef is more costly to the environment by an order of magnitude about ten times on average than other animal-derived foods, including pork and poultry. Cattle require on average 28 times more land and 11 times more irrigation water, are responsible for releasing 5 times more greenhouse gases, and consume 6 times as much nitrogen, as eggs or poultry. Poultry, pork, eggs and dairy all came out fairly similar. That was also surprising, because dairy production is often thought to be relatively environmentally benign. But the research shows that the price of irrigating and fertilizing the crops fed to milk cows as well as the relative inefficiency of cows in comparison to other livestock jacks up the cost significantly.

    Actually, with proper seasoning, you can make most other meats taste very close to steak. Once drown in A-1, covered in dry-rub, and dipped in Au Jus, you only barely taste the actual flavor of the meat.

    Ignoring what is implied here by "proper seasoning", I'll just note that I can tell the difference, even with such dousing (and in the absence of texture clues like the difference between eating steak and chicken breast). For example, I can distinguish between beef and pork sausage or between ground beef and ground poultry. My tastebuds are rather insensitive too.
