I disagree that intentional pollution only requires "simple compensation" or even double compensation. Exodus 22:5-6 is addressing unintentional consequences. Intentional pollution would be the same as arson and, therefore, outright theft and would, thus, require either four or five times restitution, depending upon the nature of that which is polluted. More on this can be found in my booklet Thou shalt not steal. An online version can be found at www.missiontoisrael.org/8thcom-pt1.php.
I also take pause at Jim's statements, "Pollution is a form of invasion of private property rights similar to trespassing, which legitimizes government involvement." and "3. Standards. The government may impose reasonable pollution control standards on machines, vehicles or factories in cases where there are multiple and often minute polluters. 4. Regulations. Consistent with its responsibility for protection of the public, the local government may impose fire, smoke or other pollution regulations to minimize the risk of damage to society at large. Reasonable graduated fines may be imposed based on the level of pollution, recognizing that zero or extremely low levels of pollution are utopian goals."
This is a difficult area. It is my opinion at this time that instead of government regulations, the judges would set fines for different levels of pollution and leave it to the individuals to police themselves and/or pay the consequences.
