Capitalism is the protector of a human being’s environment as opposed to the protection of the environment at the expense of an individual’s well-being.
If one pollutes on one’s own property, that is their right (but in doing so, you reduce the property value which would not be in one’s self-interest). However, if one’s pollution spreads to another’s property and causes objectively provable damage, the owners of that property can sue for damages (trespass).
The right to property is not permission to damage or pollute the property of others. Historically, the privately-owned locks and streams of Scotland were far cleaner than the government-owned rivers of 20th century socialist India.
As for disposing of pollutants from industrial development, this requires a technological solution — and capitalism, as the social system of innovation and technological progress is the best suited to provide a solution.
