Multiple choice

What is the precautionary principle, and how does it apply to environmental restoration?

  1. The precautionary principle states that when there is a threat of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent or minimize the damage

  2. The precautionary principle states that environmental restoration should always be carried out, regardless of the cost or the potential risks

  3. The precautionary principle states that environmental restoration should only be carried out if there is a high probability of success

  4. The precautionary principle states that environmental restoration should only be carried out if it is economically beneficial

A Correct answer
Explanation

The precautionary principle states that when there is a threat of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent or minimize the damage. This principle applies to environmental restoration in that it suggests that restoration efforts should be undertaken even if there is some uncertainty about the outcome, in order to avoid the risk of irreversible damage to the ecosystem.
