I was listening to the radio a few days ago and the host was reading off random facts just for fun/entertainment.
One of the things he mentioned was that it takes 3000 cows to produce all the leather footballs needed for an entire NFL football season.
Kinda makes you think twice or thrice about supporting the NFL.
It is unfortunate that so many sports (especially at the professional level) "require" leather or other animal products in their footwear or other equipment such as baseball gloves, basketballs and footballs.
When I was in high school many years ago our Physical Education teacher/head football coach went out of his way to order all non-leather footballs and basketballs for use on the sports teams and P.E. classes. He did that specifically because of the issues I brought up back then when I was a super-activist in school.
