"Man vs Wild" in a nutshell

(I'm not the down voter) Is there a specific cultural group your referencing? Don't get me wrong, I do think we should be moving away from eating meat for environmental reason. It's just that for a wilderness survival situation, cooked meat is one of the best sources of energy.

Eating meat is much more difficult, you have to hunt it, then cut out the eatable meat and after that even make a fire and cook it, how do you do this without any tools?! You can just eat a plant nearly as it is, that's much less effort! Eatable roots are also available year round! And because of the energy, plants need much less energy for digesting, meat needs much energy while digesting, therefore it makes you tired! I have to say i'm not a vegan only vegetarian ;) Bear Grylls just eats this shit to make a good Show!

Meat give provides more energy that most vegetable matter, especially wild roots and berries. For example there are 250 calories in 100 grams of meat, but only 28 calories in 100 grams of turnip. I mean if you can gather enough nuts you are good for a while. Acorns are closer to 320 calories, but they are seasonal. So if we are dropped in the woods in January, you are digging in frozen ground for a sad 30 calories.
