Plese tell me, before I chose whether to waste more time on you; are you actually just ignorant or do you in truth not acknowledge the following things:
Research has shown smoking to be bad for your health in a variety of different ways.
Research has shown that burning fossil fuels result in an acceleration of the global climate thus resulting in a variety of different natural disasters such as drought.
Reseach has shown that meats such as red meat and processed meat (e.g. bologna and bacon) are bad for your health and among other things will cause an increased risk of cancer, high blood pressure, increased cholesterol levels and you know... fatness.
If you do recognise at least the first two statements I will advice you to have your school tuition money refunded. If you furthermore do not even accept the third statement I will leave you with this link that WHO that it took me a whole of 1 minute to find that adresses at least one of the claims in the third statement. It would not take neither you nor me much more time to find other links supporting my "claims".
I will leave you with this. Do you acknowledge that eating meat is not necessary? That there are plenty of plant products that are actually higher in protein than meat thus rendering meat obsolete in a strict health based sense (not taking into account the precious nice sensations they seem to arouse when coming in contact with your tongue). That meat takes more space and recources to produce and thus require greater stretches of land (e.g. rain forest). All these things are pure logic and if you cannot fathom this, then I do not need to spend more time on you.
And btw. is it up to me to support it? Is this part of the reddit policy? Is this a dissertation or an academic paper? Go back to school for it seems you have much to learn, still. Just acknowledge that your are defensive because you believe me to be attacking your lifestyle and you do not want to change it... and you probably think I'm not nut vegan who is so holier-than-thou. There is no need for you to defend anyones rights - especially not at the cost of ignoring the most well-documented "facts" (I admit most "facts" have a habit of changing over the years as we learn more).
