our way of eating grass

I made a doodle once - just some text - it said:

Cows are our way of eating grass.

That kind of extends to all the animals we eat - chickens - ate seeds and insects and other stuff they could find.

Goats - shrubs in hard to reach places.

Pigs - eat pretty much anything...

Then more recently humans just liked the taste of meat so much they went into mass production, and something weird and very stupid happened... we got so good at growing food that we started to feed it to our livestock. Of course it makes animals ill to eat stuff their digestive systems hadn't evolved to eat - but that's OK we have medical science - so we can pump them full of drugs and anti-biotics and growth hormones - etc. Ok so it changes the meat to do that but we have chemicals and flavourings and... when we get ill from eating that changed meat - well, medical science comes to our rescue too - statins, insulin, etc.

I think the human race is doomed.

Guardian comment:
I was wrong about veganism. Let them eat meat – but farm it properly.
