I disagree. There are practical limits to what we are responsible for. And there are current obligations and responsibilities we have for ourselves. Just because we know of something does not make us responsible for it. Proximity and risk also play a role.

I am obligated to my family and to myself. To provide for them as an example. But I would also be able to fly across the world and feed a starving child, in theory. But my obligation to my own family, and myself outweighs that. There would also be risks to the journey. Consequences with those actions as well.
