Once a corporation is permitted to do a legal activity regulatory law is set in place to prevent that corporation from putting into the public air, water, or where ever they can, toxic pollutants. Fines set to punish a corporation are for breaking the regulation not for polluting and damaging the health of the public. To the corporation a fine for poisoning the public is just the cost of doing business.
The way forward to stop pollution is to not give permits for polluting industries. There would then be no pollution. Should a corporation attempt to operate without a permit they can be stopped from criminal behavior and have property seized and management arrested and confined.
