Precautionary principle idea – UGC NET Question

The precautionary principle acknowledges that environmental systems are complex and scientific understanding is often incomplete. It states that where potential harm is serious or irreversible, waiting for perfect certainty can result in unacceptable damage. Decision-makers should therefore take reasonable, cost-effective preventive measures even when some scientific questions remain open.

Option A:
Option A is incorrect because it demands complete scientific certainty before acting, which is exactly the approach the precautionary principle argues against.

Option B:
Option B is correct because it closely matches widely accepted formulations of the precautionary principle used in international environmental agreements.

Option C:
Option C is incorrect as it gives priority only to economic growth and sidelines environmental risks, contrary to the principle’s insistence on protecting the environment under uncertainty.

Option D:
Option D is incorrect since the precautionary approach responds to uncertainty by urging caution and preventive action, not by ignoring environmental concerns.
