Well if a farm has 150,000 chicks a day that they have no use for, what would it be like to put 150,000 a day outside?
I mean that's over 1 Million a week, 4 or 5 million a month, and 52 million a year. No way could they sustain those numbers for free ranging on a farm. If there is no profit to be made off of them, then there is no way anyone is going to pay to care for and feed them.
The grinder is actually pretty human compared to putting that many outside and letting the natural predators rip them apart while they are still alive.
In our sterilized industrial society people seem to forget about the fact that animals are killed to feed us. Also, humans are one of the few organisms on this planet that only on rare occasions die while something is eating them. 99% of all living things die while watching something eat them.
They've even done studies to show that planets have "feelings" so to speak which means that even living as a vegan you are still killing and injuring a life form.
On planet earth, whether plant, animal, or microbe something must die in order for it to live.
Consider when you eat fruit that you are eating an egg. Taking away that plant's future.
Even plants use other dead plants and animals for nutrients.
I personally thoroughly enjoy interacting with animals and growing plants. To me, children and animals are the innocents on this planet that need the intervention of rational & compassionate adults on their behalf.
Every living thing has a what I call a life force that has value. Unfortunately all things must die.
I agree with a statement I once heard made by an Australian Surfer, "When humans go into the ocean they become part of the food chain, and they are NOT very high up on it." The same is true for the wilderness if you don't have any weapons available.
The grinder may be sad and seem cruel, but in the overall big picture it really isn't.
