It’s almost laughable, the "humanely slaughtered" carcasses of animals are frequently coated in animal waste and exposed to high levels of pollutants, and in most places on the planet that's even more.
One could argue that the slaughterhouses are just like the airlines in that they kill a lot of the animals, but do so in safe and controlled conditions. But again, that would completely ignore the rampant animal cruelty that has been allowed to happen on our behalf.
And in terms of the ecological ramifications, there seems little point in continuing our destructive trend if there are alternative options. It makes little sense to continue eating livestock in dire conditions, as we have.
In terms of ecological implications, we are being more concerned with agriculture, but we must also be concerned about other industries that have an impact on environmental issues. In terms of livestock production, it is easy to criticize the animal husbandry practices that produce meat, so there is no reason to question the ethical nature of what we eat.
The cruelty that goes on inside our bodies is not merely being exposed in advertisements but is a constant aspect of eating and breathing as well.
With so many choices available from food manufacturers to the consumer it is surprising that most aren't willing to think critically of their choices. If you're like me, you've probably thought "why do I need to eat a burger when I could make healthier choices with my food and save money."
In my personal opinion, food is fuel. And fuel doesn’t have to taste good all the time.
