When faced with uncertain environmental risks, what action does the precautionary principle recommend?

The precautionary principle recommends taking measures to prevent potential harm when faced with uncertain environmental risks. This principle emphasizes proactive action rather than reactive solutions. It acknowledges that in situations where there may be serious or irreversible harm to the environment or human health, and where scientific understanding is incomplete, it is better to act cautiously to avoid potential damage.

The rationale behind this principle is to prioritize environmental protection and public safety, even in the absence of conclusive evidence of harm. By advocating for preventive measures, the precautionary principle encourages decision-makers to weigh the potential risks and take action to mitigate them, rather than assuming that a lack of clear evidence justifies inaction. This aligns with the broader goals of sustainability, which seek to protect both the environment and human wellbeing for future generations.
