The climate has always been changing and nothing Man can do is going to change that. Can we stop the climate from changing? Not until the technology is developed if it is even possible, to control the natural climate patterns.
Has man sped up the change, likely we set into motion a change over s hundred years ago, but in the last 30-50 years we have at least in the USA, been observing and realizing we need to stop taking the environment for granted and be responsible.
We in the USA can not mandate to China, India for that matter the rest of the world how they should be protecting the environment.
But companies that can be proven to go against a national policy of protecting the environment should pay extremely heavy fines beyond a slap on wrist. If a single person in a company caused the problem, it should be that person that pays the fine.
