What does the 2nd Natural Step address?

The second principle of The Natural Step focuses on the concentrations of substances produced by society. This principle emphasizes the importance of maintaining ecological integrity by ensuring that human-produced materials do not accumulate in the environment at harmful levels. It underlines the concept that certain substances, like heavy metals, persistent chemicals, or other hazardous materials, can disrupt ecosystems if they build up beyond natural concentrations.

By adhering to this principle, organizations and societies are encouraged to minimize the use of these harmful substances in production and consumption processes, seeking safer alternatives and more sustainable practices. This helps protect ecosystems and human health and promotes a circular economy where materials are reused and recycled, thereby reducing the overall impact on the environment.
