Keeping marine life safe is crucial for the health of the oceans. By setting up marine protected areas (MPAs) that limit fishing and other harmful activities, we can ensure that marine species survive and thrive. A study looked at fully protected areas where no fishing is allowed and found that these areas help increase biodiversity and protect marine life. The research team from Atlas of Marine Protection updates annual reports on the state of MPAs in the US waters to track progress towards effective marine protection. This shows that by protecting certain ocean areas, we can help species survive and provide food for millions of people.
