This actually happened to me as a friend of mine going back to Italy was going to throw out several packages of sliced pork. I know what I would do and did but am curious to see how others view and or would handle it. As much as I believe it is wrong to kill and eat animals for the sake of our palates I also believe it wrongful to waste something that could potentially be used.
Answer on What would you do if you knew someone was going to throw away a package of meat?
I'm vegetarian but I would still find a use for the meat.
As me taking the meat in this case would not directly fund or otherwise support the slaughter market I would not feel any guilt in using the meat for feeding my cats and dog. If the packages were exceptionally big I'd also consider indirectly giving it to the hungry.
As wrong as it is to kill animals it would be like their deaths were for no reason at all if someone didn't use them.
