Readers explore issues of diet, agriculture, ethics and climate change. May 3, 2021 To the Editor: Ezra Klein’s column about the dangers and immorality of meat consumption is welcome, particularly the comments on the ethical issues involved in wide consumption of meat. Perhaps he is correct that government action is needed, but if “market” means anything, then consumers should be able to make some of the change happen by themselves. Like Mr. Klein, I was a meat eater, and I made the change to vegan perhaps 10 years ago, when it wasn’t as easy as it is today to find alternatives, especially for protein. Aside from the health effects, which may or may not become manifest for me in the long run, there is no sense of ethical superiority.
