Everyone's survival is dependent on the death of others.... even Class 6 vegetarians who don't eat anything that casts a shadow.
Expecting to be able to survive without incurring death unto other sentient beings is unrealistic, and seeing this reality as it is, we should not set unachievable expectations which will cause us unnecessary and additional suffering.
"Do not force others, including children, by any means whatsoever, to adopt your views, whether by authority, threat, money, propaganda, or even education." - Ven. Thich Nhat Hanh
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
