Focusing on marine protected areas (MPAs), this critical analysis examines their rise in marine policy and the scientific backing for their popularity. It highlights the influence of policy networks in promoting MPAs, revealing how some advocacy based on limited evidence has blurred the lines between science and politics. The study assesses the ecological effects of MPAs, finding little evidence of positive impacts on fish populations, and explores confusion surrounding marine conservation zones in England. Ultimately, it warns of the risks scientists face when politicizing their work, potentially undermining public trust.
