A few reasons why meat eating is no more harmful to the environment
Myth 1: 10kg of grain = 1kg of beef.
On the face of it this appears correct as you can produce more calories from vegetables than from meat on arable land. The key here is the words 'arable land' - there is significant land area which is not suitable for crops but which is suitable for grazing livestock
Myth 2: Methane production from livestock is contributing to greenhouse gasses
While livestock do produce methane it pays to bear in mind that the carbon from which this methane is formed comes from grass and other feeds, not fossil fuels. As such is part of the natural carbon cycle. Secondly, techniques such as mob grazing result in MORE carbon being fixed by grasses in their root systems than is emitted in methane. Centuries ago, tens of millions of bovines roamed the grasslands of North America and Africa - our climate didn't collapse then.
Myth 3: Switching to a vegetarian diet will save the planet
If more people switched to vegetarianism then we would be able to support a larger population. Ironically this is the biggest problem of all. Overwhelmingly it is PEOPLE that damage the environment. The surest way of managing environmental damage is to reduce the world's human population. By increasing food supplies you are only increasing the global population.
