Vegetarian diets are not going to save the planet

I'm not sure what to make out of such a text.

Basically what the text says is that plant-based food usually is less resource intense and thus better for the environment, but there are also other factors and plant-based food production isn't perfect. (Independent of the question whether all the other things he says are true.)

So the headline is obviously strictly true, but highly misleading. A more accurate one would be "Vegetarian diets are good for the planet, but they're not the whole solution".

And a local, seasonal vegetarian diet is a lot easier to implement in a city environment than a local, seasonal omnivorous diet. So vegetarian is still likely to be a better option in the future, especially if you consider vat-grown meat to be a vegetable.

Most of the arguments are just an appeal to nature. Doesn't address cow burps as a major source of pollution. Seems to be making a food miles argument, when what matters is carbon per pound of food. Transporting by boat is highly efficient and a high percentage of the cargo is food. Driving to pick up your food from 3 farmer's markets can create more pollution than would be used to transport them from across the world, because the food is such a small percentage of the weight of your car.
