Is it? As a rule of thumb, each layer of indirection in the food chain retains only 10% of the energy from the previous layer. If we eat the stuff we give to cows (which is what vegetarians do) then we would need only 10% of the land to farm it.

What unit of energy? Calories?

It's a percentage, so why would the units matter?

> Meat-heavy diets not only risk our health but that of the planet, as livestock farming on a massive scale destroys habitats and generates greenhouse gases. Well that's a bit over the top... Seems like they could have stuck with the "vegetables are good for you" line and had just as relevant of an article.

I don’t think it is controversial. I thought the huge environmental impact of meat eating was common knowledge.

Being pedantic. If we eat the stuff they feed to the cows I eat we would die. Grass is not human digestible.

My point being the problem is not meat which is a natural part of our diet (and is traditionally raised on land not well suited to crops) but the crazy frankenmeat many are reduced to eating due to overpopulation.

The truth is over the top?

Because no vegetable farm ever caused habitat destruction or environmental damage...

It's interesting how your response to the point that farming plants is far more efficient and sustainable than farming animals is "but some vegetable farms are bad for the environment, too!"

Isn't it rather exaggerated? Doesn't agriculture as a whole cause around 11% of emissions but car driving and heating/cooling causes around 30%?

So if we all stopped eating meat we could cut emissions but a couple of % but if we all stopped driving and turned our heating down/up we could actually make a real difference?

And as you well know, no one is suggesting that, so why is it worth to mention?

Your phrase "each layer of indirection" made the following analogy pop into my head: eating meat is like using an electron app running in a VM. I suppose "bare metal" would be if we could ourselves photosynthesize, alas.
