What's right and wrong?

A problem I noticed is what about people with allergies to peanuts, tree nuts, and/or legumes. Those people would lose out on protein which is vital to the human bodies, and saying eating eggs as a substitute doesn't change anything because the video also points out the cruelty in the egg industry.

Also, for a personal note, about 80% of my meals consist of meat and I already eat less than I should. Cutting out meat would really harm me... plus I can't stand the taste of vegetables.
