In response to “Sustainable eating” from April 23, I wonder if the writer thinks humans should be vegan since the animals we eat are, or if our carnivorous tooth structure is some left-over evolutionary thing.
Consider this: our planet will not be sustainable until humans stop over-breeding. The climate is changing. Where is the vegan food to be grown for all the four-legged and two-legged animals? We must address these larger problems before any “sustainable eating” can occur.
As to the “damaging methane and nitrous oxide from animals,” what do you think you release from your digestive tract?
