According to this graph from the Daily Livestock Report, we are way past Peak Beef. U.S. beef consumption has been dropping for the last 40 years, and projections put it back down at 1950s levels this year, which would mean we're eating less meat than at any time in the last 50 years. Americans are eating a lot less meat overall, but beef and to a lesser extent pork have seen the biggest reductions — which is cool, because cattle and pigs are the most resource-intensive livestock.
Tom Laskawy speculates about the causes for the drop-off:
What really struck me was how this latest news mirrors the trend in consumer attitudes on meat-eating uncovered by the food industry's own market research. It turns out that since 2007, there has also been a 12 percent drop in the number of consumers who report that they have "no problem" eating meat or dairy (a bare majority of respondents currently feel that way).
Meating half way: Americans opt for less, Grist.
