Crop rotation is a recognized way to keep soil and the food ecosystem healthy. Now, scientists are saying that rotation could be a useful tool—in the sea. Researchers tracked a shallow-water, near-shore species used for food: sea cucumbers. They're easy to harvest and are fairly valuable. But those same attributes mean they're easy to overharvest. The practice has put some sea cucumber species at high risk of extinction, even in a relatively well-managed area, the Great Barrier Marine Park in Australia. In 2004 authorities split the Great Barrier Reef into 1 54 zones, where each zone was fished only once every three years. Fishers rotate through the region. In computer models, the researchers ran through dozens of simulations of each zone, both before and after the divisions took place. The trials revealed that even with an identical and low-catch allowance in all cases, the sea cucumbers would recover more fully under the rotation strategy.

AI explanationShows the answer. Tap to open.

Printed "exploitation", the speaker says "rotation"

Explanation: Listen again to "Crop rotation is". The page shows "exploitation", which starts with a different letter, so hear the full word.

Printed "licenses", the speaker says "scientists"

Explanation: In the audio you hear "scientists are saying". The printed word "licenses" begins with a different letter and does not fit, so trust the audio.

Printed "indulgence", the speaker says "practice"

Explanation: Here the speaker says "The practice has". "indulgence" starts with a different letter and is longer, so listen for the shorter word.

Printed "avocations", the speaker says "simulations"

Explanation: The speaker says "dozens of simulations of", not "avocations". Both words start with different letters, so wait for the whole word before you click.

Printed "snapped", the speaker says "low catch"

Explanation: Listen for "low catch allowance". "snapped" looks long and ends differently, so listen for the short phrase in the audio.

"sea" matches the audio

Explanation: "food: sea cucumbers" sits next to a change and may distract you. It is spoken exactly as printed, so do not click it.

"harvest" matches the audio

Explanation: "They're easy to harvest and" is right beside the altered word and may trick you. This word is spoken exactly as printed, so do not click it.
