The precautionary principle in environmental science emphasizes the importance of taking preventative action in the face of uncertainty regarding environmental risks. This principle advocates that when there is a potential for harm to the public or the environment, and scientific evidence is lacking or inconclusive, measures should be taken to avoid or mitigate that harm. Emphasizing caution helps protect vulnerable ecosystems and human health, encouraging sustainable practices. By prioritizing precaution, policymakers and businesses can minimize adverse effects and promote long-term environmental integrity, thus supporting ecological recovery and sustainability.
