may I ask whom you think is taking the lead in this area? Surely some country must meet this criteria?
What kind of sacrifice or pain? What steps have you done that constitute sacrifice and pain as part of your contribution? Yeah, being trite here, but I rarely find those professing a need for others to give up rarely do so themselves, they have endless levels of justification, usually starting with how smart they are.
Not using a car (not even having one, if it matters), conserving, recycling, buying new stuff minding that it'll eventually end up in the landfill. That kind of thing.
If you live on a farm or in the mountains, it's hard to go without a car. But living in a modern city in a first world country, there's rarely an excuse.
EDIT: also, consider stopping eating so much meat, because it's not sustainable either.
