First thing to consider, well the only thing to consider, Is! How do our activities effect the world environment. For example! PG&E can build a generation plant just outside of Bullhead AZ, and avoid regulatory problems. However that doesn't reduce pollution/poisoning our collective environment. What it does is hide what is being done by thinning the vail so to speak.
Even if you don't live in LA the problem is yours. The same way shifting manufacturing to places like China, or other places that don't have the same controls, only serve to produce more environmental issues, even if your personal space seems more palatable.
No this is a problem that is collectively shared, and all should be willing to share in the cost to fix it.
