Or don't keep cattle in the rainforest. Not every problem with cattle has to be solved by making an impractical and enormous swing in your life.
I don't think eating less meat is impractical, certainly not specifically just eating less beef, by far the most environmentally impactful one.
Should the opportunity to do so ever arise, I’ll make a note not to do that. In the meantime, as I am not a cattle farmer, I’ll continue to not eat meat.
