Pagans should support any steps that grant more freedom to any people anywhere in the world, and that limit the ability of people in power to force people to their will. Education is considered an important part of population control and of caring for the environment, and it is. But not quite the way we've been led to think. We don't need propaganda urging people to have smaller families, or to use resources more efficiently. Families take work, and resources cost money.
People already have a powerful incentive to do less work and spend less money.
We need to educate people in ways to become wealthy. We need to persuade those in power to grant their subjects more freedom and use less force to exert their will.
