Detailed explanation-1: -For example, invasive species (plants or animals that cause harm after being introduced into a new environment by humans) have repeatedly caused native species to become extinct. So it’s reasonable to exercise precaution and not introduce living things into new places without strong evidence it will be harmless.
Detailed explanation-2: -The precautionary principle enables decision-makers to adopt precautionary measures when scientific evidence about an environmental or human health hazard is uncertain and the stakes are high.
Detailed explanation-3: -The statement went on to list four central components of the principle: taking preventive action in the face of uncertainty; shifting the burden of proof to the proponents of an activity; exploring a wide range of alternatives to pos-sibly harmful actions; and increasing public participation in decision making.
Detailed explanation-4: -Strong precaution can also be termed as a “no-regrets” principle, where costs are not considered in preventative action. Weak precaution holds that lack of scientific evidence does not preclude action if damage would otherwise be serious and irreversible.
