White River Fish Sanctuary wardens patrol through the reef of the sanctuary's no-take zone in Ocho Rios, Jamaica, Tuesday, Feb. 12, 2019. After a series of disasters in the 1980s and 1990s, Jamaica lost 85 percent of its once-bountiful coral reefs and its fish population plummeted. But today, the corals and tropical fish are slowly reappearing thanks to some careful interventions. (AP Photo/David Goldman)

The site is named after Milton &quot;Sam&quot; Gray, a biologist who studied it in the 1960s and identified it as an ecosystem worth saving _ a reef not far from the U.S. coast that teemed with life, especially an &quot;abundance of diversity of invertebrates,&quot; says Roberson.

Helen Greaves, PhD Student, UCL Pond Restoration Research Group, takes samples at a wetland on farmland near Hindolveston, Dereham, eastern England, on Friday, Sept. 13, 2019. Around the world, efforts are being made to reclaim wetlands that have been filled in to plant crops or fill other human needs. Without them, species are at risk, and flooding is a growing danger. But the battle for the wetlands is a struggle. (AP Photo/Emilio Morenatti)

Diver Lenford DaCosta tends to lines of staghorn coral growing at an underwater nursery inside the Oracabessa Fish Sanctuary Tuesday, Feb. 12, 2019, in Oracabessa, Jamaica. On the ocean floor, small coral fragments dangle from suspended ropes, like socks hung on a laundry line. DaCosta and other divers tend to these underwater nurseries much as a terrestrial gardener minds a flower bed, plucking off snails and fireworms that feast on immature coral. (AP Photo/David J.

In this Thursday July 4, 2019 photo, Saitoti Petro, brushes his teeth with a stick before taking his herd to the fields in the village of Narakauwo, Tanzania. Petro says the problem now is that there are too few lions, not too many. &quot;It will be shameful if we kill them all,&quot; he says. &quot;It will be a big loss if our future children never see lions.&quot; And so he's joined an effort to protect lions, by safeguarding domestic animals on which they might prey.

In this photo taken in the early morning hours of Oct. 24, 2018, wildlife technician Jordan Hazan records data in a lab in Corvallis, Ore., from a male barred owl he shot earlier in the night. The owl was killed as part of a controversial experiment by the U.S. government to test whether the northern spotted owl's rapid decline in the Pacific Northwest can be stopped by killing its larger and more aggressive East Coast cousin, the barred owl, which now outnumber spotted owls in many areas of the native bird's historic range.

Peaks reach toward the sky in Angsai, an area inside the Sanjiangyuan region in western China's Qinghai province on Sunday, Aug. 25, 2019. Ringed by the world's tallest mountain ranges, the region long known as &quot;the rooftop of the world&quot; is now in the crosshairs of China's latest modernization push. But this time, the Chinese government wants to set limits on the region's growth in order to implement its own version of one of the U.S.'s proudest legacies _ a national park system.

A team of scientists in Venezuela is trying to weather the political and economic crisis engulfing their country to record what happens as Venezuela's last glacier vanishes. (AP Photo/Rodrigo Abd)

White River Fish Sanctuary warden Mark Lobban steers the boat while patrolling the no-take zone for illegal fishermen in Ocho Rios, Jamaica, Friday, Feb. 15, 2019. Lobban was driving a boat, appropriately called the Interceptor, up and down the coast under the same moonlit sky where 9 kilometers (5 miles) away two night spearfishermen are skirting the boundary of another sanctuary hoping to evade any patrols.

Gray’s Reef has served as a global inspiration. Following the lead of the U.S., other nations have designated similar sanctuaries; they now cover about 6 percent of the world’s oceans _ a bonanza for researchers, but more importantly an important tool for safeguarding the seas.
