Long winded, but the point is in order to stop us externalising the destructive costs of our societies towards the future, to make that future the litmus test of everything. In the form of benchmarking everything on how it impedes or improves the rights and lives of children, putting their human rights as the key stone of every decision.
It’s very hard to get adults to reason properly about the human rights of other adults, because we always tend to say “well, their conditions are their fault.” Lot of black people wind up in jail? “That’s either bad policing, or bad behavior, or both” says the adult analysis. “Lot of black children are getting substandard educations” well, this is clearly not their fault. You can say their parents are responsible, and basically abandon these kids to the mercy of their environment, whatever random spot they were born in, or you can say “the children have fundamental rights as children and these rights require us to act on their behalf as a society” and, for example, really seriously invest in and fix education. You see what I’m saying? We can get leverage on issues like race in America by using the human rights of children, free from moral responsibility for their fates, as a universal standard by which to measure our obligations. The same kind of logic applies to the environment: “is this commons being handed over to the children, its future owners, intact, or is it being degraded in a manner that violates their rights.” That gets you concepts like natural parks protection from fracking etc. very nicely.
In short, making the rights of children fully explicit, and enshrining them in our legal systems may be the shortest path forwards to creating a world in which we, as adults, are also protected. But the children first: none of this is their fault, and they should be protected as best we can.
And a rights framework for children, something simple, reasonably universal, clear and easy to work with is certainly possible. We can do this.
