According to The Times we should all give up meat saying: people will need to consider turning vegetarian if the world is to conquer climate change. Lord Stern of Brentford said: Meat is a wasteful use of water and creates a lot of greenhouse gases. It puts enormous pressure on the world's resources. A vegetarian diet is better."
It also suggests that direct emissions of methane from cows and pigs is a significant source of greenhouse gases. Methane is 23 times more powerful than carbon dioxide as a global warming gas.
In the second half of the article there are diagrams showing the cost of a meat eater's diet comparing it to the vegan diet. Of course it does not mention the cost of organic farming. Humans are designed to eat meat, otherwise we would have five stomachs and teeth like a cow. If early humans did not start to eat meat we would not be here today, not in this form at least, our brain got bigger after we started to hunt, eat meat and fat, we had to because our climate has changed and vegetation was limited throughout the winter months.
Stern says meat creates a lot of greenhouse gases, well what we are talking about is the animal farting its way through his life and it does it because its a natural bodily function on the other hand how much kettle farts depends on its diet, commercially raised cows and pigs are fed grains (which is not what they are designed to eat, cows should be grassing and pigs should be running around in the forest looking for fruits, mushrooms, roots, small animals, dead animals basically everything they can find) so a diet based on grains results in loads of methane. Another reason why organic farming is better for the planet.
Another issue here is that 1 pound of meat has a nutritional value of ca. 6 pounds of vegetables so multiply the cost of vegetarian diet by 6 but at least 3 or four and you will see that the numbers aren't so different.
Of course organic food is slow, profits, I mean the governments profits are much smaller, so it does not make sense to say eat organic and you will be reducing your carbon foot print. Instead become a vegetarian, eat a lot of grains and fruits, feel happy about being doing the right thing for the planet, but don’t be surprised if you start to gain weight, experience low immunity and be tired. Some people do quite well on a vegetarian diet, some do not. There is only one of you, as much as we look different from the outside we are different from the inside, the way you metabolize food is individual, even the shape of your stomach is different from everyone else's.
healthy soil->healthy plants->healthy animals (farting less)->healthy people->healthy thinking, speaking and living->healthy planet.
