Why not? Between the spreading of new ideas and information via the internet and the vegan marketplace explosion, today it’s easier than ever to live cruelty-free—and it’s only gonna get better. By avoiding the consumption of animals and their byproducts as well as their exploitation for testing, you’re really saving a bunch of birds with one stone:
This one’s pretty obvious. You have taken yourself out of the animal-cruelty equation. By avoiding not only meat but dairy, eggs, honey, leather, wool, and the like, you are not justifying the animal exploitation process in any way. You cannot bring the industry down yourself but by voting with your dollar you have chosen to support plant-based industries instead.
Always a fight, but the evidence seems to be pretty one-sided when Science is your guy. You can live a perfectly healthy life on a completely plant-based diet. Yes, some of our foods are fortified…just like their animal-derived counterparts. Studies do tend to show that a plant-based diet can help prevent a ton of diseases, such as diabetes, heart disease, and some cancers.
“It would take so much more land to support a vegan diet.” Really? How much land does it take to feed that cow to feed that man? How much water? Exactly. By eating as low as possible on the food chain, your water/energy-to-protein ratio is much more efficient. By not farming animals, you encourage biodiversity, better maintain ocean life, and discourage deforestation. Countless studies have shown the environmental advantages of a plant-based diet—check out this page from The Vegan Society.
