I haven't read the whole 13 pages but essentially, YABU.
People all have different views and I respect that, the world would be a very boring place if we didn't however I loathe it when people try to push their own views / values down other people's throats.
I eat meat and I enjoy it - the thought of going veggie (let alone vegan) frankly makes me want to kill myself.
To address you points OP.
- Cutting out meat does NOT make you healthier. If you eat a modest amount of good quality meat then your health benefits. We are designed to be omnivores, not herbivores. It is possible to be very healthy as a veggie / vegan but the overwhelming majority of people lack the nutritional / culinary knowledge to do so. You really need to know your stuff to thrive on a veggie / vegan diet. (DW is a doctor and has seen deficiencies caused by vegan diets first hand).
- Cruelty is NOT inevitable in the meat / dairy industries! One thing that extremely high animal welfare standards does is to cause prices at the supermarket to rocket and most people are not prepared to pay them.
If people were prepared to dig a little deeper then corners regarding animal welfare would not have to be made in order to keep costs under control.
It is the consumer NOT the farmer that is responsible for animal welfare, if anyone reading this is concerned about animal welfare but doesn't want to give up meat then abandon the supermarket and find yourself a good independent butcher who only sources from farms with welfare standards that you are happy with. Vote with your feet (purses) and you will see welfare standards rise across the board as demand for 'cruel' meat decreases.
- It is true, cows emit greenhouse gasses. So do cars, power stations, factories etc. If you want to help global warming then why not switch off lights you're not using, cut down on car journeys, turn appliances off rather than use standby mode.... there is loads that you can do.
Thinking of buying a 'green' prius - well first familiarize yourself with the environmental damage involved in mining the materials for making the batteries. Over half of a cars carbon footprint is down to it's manufacture and delivery to the customer so actually the best thing you can do is get a mechanically simple car that is likely to have a long lifespan. I have an old land rover with a dirty great gas guzzling V8 engine however given that it's over 20 years old it's total carbon footprint is actually less than that of a prius which has been driven for 10 years and covered 150,000 miles.
Soy, a common ingredient in veggie foods is also horrific for the environment (but the preachy veggies don't tell you this - I'd wager that the majority don't even know themselves).
It is predominately grown in South America and other such tropical places. It is also a very nutrient hungry plant so one of the most widespread lethods of growing it is to crop down and burn a few acres of rainforest (home to thousands of animals and trees) and plant the crop.
Once 2 or 3 crops have been grown the soil is exhausted so they move on and chop down a few more acres, while the forest thy chopped down takes a couple of hundred years (minimum) to recover.
Doesn't sound very environmentally friendly to me!
I am a farmer (beef and lamb mostly) and refuse to supply supermarkets. I sell my beef through local markets, direct from the farm shop and through local butchers and restaurants. One of my steaks will cost you 3 times what it will in ASDA or Tesco but I promise you that's not profit.
That money pays for meat which is certified organic, exceptional animal welfare and extremely high environmental standards on my land.
I could easily raise double the number of animals on my land that I do and still be considered to have 'good' animal welfare. They all live outdoors with 2000 acres to roam over. I don't kill too many predators on my farm, I spend money making pens and buildings very secure - only resorting to shooting the really persistent ones. I have large areas of woodland and fallow land, lots of extra wide hedgerows for wildlife and ponds specially dug to nurture a population of great crested newts which were discovered a few years ago.
All this costs money - money which has to come from the sale of my produce. Next time you're in the supermarket looking at a '3 chickens for a tenner' deal (well done Tesco) then just take a long hard look in the mirror.
