For the animals
Preventing the exploitation of animals is not the only reason for becoming vegan, but for many it remains the key factor in their decision to go vegan and stay vegan. Having emotional attachments with animals may form part of that reason, while many believe that all sentient creatures have a right to life and freedom. Specifics aside, avoiding animal products is one of the most obvious ways you can take a stand against animal cruelty and animal exploitation everywhere.
For your health
More and more people are turning to a vegan diet for the health benefits: increased energy, younger looking skin and eternal youth are just some of the claims from enthusiastic plant eaters. Well, eternal youth might be a bit optimistic, but there are certainly many scientifically proven benefits to vegan living when compared to the average western diet.
For the environment
From recycling our household rubbish to cycling to work, we're all aware of ways to live a greener life. One of the most effective things an individual can do to lower their carbon footprint is to avoid all animal products. This goes way beyond the problem of cow flatulence!
