In a free society, the approach to dealing with environmental pollution would be rooted in the principles of property rights and voluntary exchange. Pollution can be seen as a violation of property rights, where one party's actions negatively impact another's property without consent. In such a society, there would be a strong legal framework that allows for the protection of property rights, including recourse for those harmed by pollution.

For instance, if a factory pollutes a river and the pollution negatively affects the property or health of individuals downstream, those individuals would have the right to seek damages and restitution through a court system that respects and enforces property rights. This would create a financial disincentive for polluters, as they would be held accountable for the costs of their actions.

Moreover, a free society would likely encourage the development of private solutions to environmental challenges. Entrepreneurs and businesses would have the incentive to innovate and create products or services that reduce pollution, as there would be a market demand for cleaner alternatives. This could include technological advancements that minimize emissions or more efficient waste management systems.

In addition, voluntary associations and non-profit organizations could play a role in monitoring environmental conditions and advocating for responsible practices. These organizations could be supported by individuals who are concerned about the environment and wish to contribute to its preservation.

Overall, the key to addressing environmental pollution in a free society is to ensure that property rights are upheld and that the costs of pollution are internalized by those who cause it, rather than externalized onto society or the environment.
