From Mother Jones:
Let’s try a middle path. We’re not all going to become vegetarians, but most of us can stop giving our money to factory farms—the biggest and worst offenders, from a pollution and public health perspective. We can eat less meat than we currently do, especially meat from methane-releasing ruminants (cattle, sheep, goats, etc.). Just because a sudden global conversion to vegetarianism would have jarring effects doesn’t mean we can’t gradually reduce our consumption of meat, giving the market time to adjust. We not only can; we must. After all, with the world’s population slated to grow to 9 billion by 2050, well be needing to take some of the 25 percent of the world’s land area back from the cows.
