The article was about large-scale production of animals by multi-billion dollar conglomerates, not about veganism or vegetarianism (though there is of course a connection). Thus, it owes readers no alternative lifestyle choices.

If you are disgusted by the reality presented in the article, then its incumbent upon you to find an alternative you find more humane.

Cruelty to animals/non-vegetarianism/humane treatment of animals etc. are all highly subjective and personal choices. You won't find all the easy answers in one article.
