How?
ok, fair enough- If a national corporation with offices in multiple states violates, let’s say, air pollution regulations then the EPA can file and states can join a single case. That partnership is stronger than if the same set of cases was stratified across multiple state jurisdictions due to states having their own unique set of rules and regulations... the larger corporate entity is going against the relatively smaller state entity instead of the federal and state agencies combined
Also, as I mentioned in the last portion of my first post, I believe states would race to reduce restrictions in order to entice larger companies to do business in their respective states, weakening environmental protections
