I mean: honestly, it's not like there isn't any alternative to it.
Besides the fact that fur production harms the environment, it is simply unnecessary and just f***ing cruel.
I am sorry to ruin your day, in case you have a "nice" sleeping bag or stroller liner with lambskin in it, but let me ask you a question:
Do you think it is fair to have the child of another animal killed in order to wrap your own baby in a cosy and warm piece of skin and fur?
PLEASE, inform yourself well and buy alternatives!
