Edit: Surprised at all the vegans in this thread. I didn't think there were so many of you. I'm glad you care so much about animal rights, that you're willing to forego eating them and using products made from them.
If you're not vegan and have moral objections for this, maybe you should look at yourself first and all the animal abuse you sanction by eating animals and using animal products.
Did you know dairy cows have to be pregnant to produce milk? They're artificially inseminated throughout most of their lives. I hope everyone complaining about this also complains about ice cream and cheese. Or else they would be hypocrites who just want to blame others but never look at themselves.
Could you imagine if we extended the life span of every person on earth by 30 years? We would be so fucked population wise. Plus we already have issues supporting our elderly population, what happens a couple decades later, when the average age of the retired is 95? Capitalism would need to be entirely restructured... to the point where it is no longer Capitalism.
And you think extending people's lives will change that, or somehow make that equation better? If anything it would just be used to literally put people back into indentured servitude just to stay alive.
