Jonah Goldberg considers the silence of the felines:
Well, the inconvenient truth is that cats kill more American birds, particularly songbirds, than DDT and pesticides ever did. Wisconsin is considering allowing residents to shoot feral cats in part because a respected study found that felines kill between 7.8 million and 217 million birds in Wisconsin alone. Data from a Michigan study suggest that some 75 million birds are killed there just in the summer alone.
Estimates for how many birds cats kill in the United States vary almost as widely. The lowest estimates are around 100 million and go up to the 2.5 billion, though the consensus seems to hover around half a billion. What this leaves out, of course, is that many vulnerable bird species are particularly threatened by cats (and, alas, sometimes dogs as well), a non-native predator that often kills small animals for the fun of it….
For example, Carson’s memory is still invoked regularly by the anti-pesticide movement today. Anti-pesticide activists claim that some 67 million birds die every year from such chemicals. In other words, compounds that make food cheaper and more abundant for everybody kill between 10 and 20 percent of the number of birds killed by cats every year. And yet, environmentalists are terrified of making cats a major issue, because it will split the movement. An official at the World Wildlife Fund calls the cat issue a “third rail” for environmentalists.
Get rid of a bunch of filthy beasts AND upset the environmentalists while preserving nature. Do you see any downside? Because I sure don’t.
