At least it'll be less habitable, because the climate change at hand is a whole lot faster than what it has naturally been.
How do you figure? The global mean temperature has been flat for 17 years now. Where is this "whole lot faster" of which you speak?
You can keep him tied up in court forever.
That's the key, once again: the government - including the courts - have become skewed toward favoring massive numbers of lobbyists and legal teams. So even though the neighbor might have a case, he could never win. The government has become the enforcer of rights violations.
Polluting public property should be a criminal act not a civil issue. With public property the government could also sue.
So long as you believe that, or that another law is going to stop pollution on public grounds, politicians and their cronies will continue to laugh at you. So long as there exists public property and the potential for government to violate the rights of one group to benefit another, there will always be lobbyists buying politicians. The solution is not to pretend that another law against companies is going to fix the problem. The solution is to prohibit government violation of individual rights: privatize all property, and restrict government to the minimal role of police, courts, and military, to only uphold and protect individual rights. Such a system, so long as it existed, would offer no incentive for lobbyism as an industry to exist.
