José "Josh" Catzim Castillo, a 25-year-old lobster fisher, circles a hollow concrete box resting on the seafloor, just off the coast of Mexico's Yucatán Peninsula. He slips a snare into the box and shakes it. Three spiny lobsters, or langostas, shoot out and try to flee, but Castillo is too quick.
He surfaces, hoisting his catch. Its tail snaps loudly, and its antennae makes a high-pitched squeak. Castillo's father, Pablo Catzim Pech, 51, hauls the spiny lobster into their fishing boat. The creature is one of most sought after crustaceans in the Caribbean. Marked by its thick antennae and sharp spines that run the length of its body, it can sell for $40 a pound in the United States.
Castillo and his father Pech are part of a collective with exclusive rights to fish spiny lobsters in Maria Elena bay, part of Mexico's Sian Ka'an national park. The lobster fishers of Maria Elena are an ecological success story. Even as the lobsters face increasingly chaotic weather and overfishing around the Caribbean, they are flourishing in the bay, thanks to the efforts of the collective.

When it starts to rain, Pech dips two rags in the ocean and spreads them over the plastic crates attached to the sides of his boat, each one filled with dozens of lobsters submerged in saltwater. Pech steers the boat back to shore, leaving Castillo with only his mask and flippers — and no life jacket — in the ocean behind him.
"Sweetwater kills the lobsters," Pech said.
Climate change is bringing more intense rainfall to the region, flooding the bay with freshwater, menacing the lobsters, which can only survive in saltwater. The fishers say they are finding it harder to understand the weather. To make matters worse, rising seas are eroding the narrow beaches of Maria Elena. Seven years ago, a hurricane destroyed all but one cabana along the beach, while rainwater stagnated in the bay and killed many lobsters.
Then there is overfishing. Since the 1980s, lobster populations have dropped as much as 40 percent across the Caribbean, according to Eloy Sosa, a marine biologist at the research center Ecosur, who works with Castillo's collective to protect the spiny lobster. The crustaceans are diminishing in number and becoming harder to find, so fishers are having to dive as much as 40 meters underwater, weighed down by oxygen tanks, to try to nab them.
That's not the case in Maria Elena, where the lobsters are thriving. The bay's newest lobsterman, Jose Eduardo Uitz, actually came to the reserve because he no longer wanted to risk his life going deeper into the ocean to catch lobsters. In Maria Elena, they lie just under the surface.

Maria Elena wasn't always a lobster haven, however. The collective was granted special permission to fish in the reserve after it was declared a UNESCO World Heritage site in 1987, but it wasn't until a decade later that the collective adopted sustainable fishing practices.
"Nobody knew anything about sustainability back then. Fishermen would take the eggs from a pregnant lobster, go home and scramble them with chicken eggs," Pech said.
Things changed when scientists like Sosa began conducting workshops inside the park, showing the fishers how to protect the lobsters by allowing them enough time to grow and reproduce. Thanks to the collective's efforts, lobster numbers have risen in Maria Elena, though they have yet to return to levels seen in the 1980s.
"The old men say that when they first arrived, there were so many lobsters that they even used to walk up to the shore," Castillo said.
Today's fishers are far more responsible than their forebears. They treat the crustacean like an investment and guard it jealously, hoping to nurture it back to its former glory.

"Being in Maria Elena is a privilege," Sosa said. "If an associate breaks the rules, the punishment is tough. They could expel you from the collective."
A descendant of Maria Elena's founders, Castillo knows this better than most. He is still trying to earn his place in the collective, waiting for a position to open up in the group of 50. For now, he is just an employee of his father, who is a member.
"I hope he will take charge of everything. I am teaching him everything about the lobster fields, the reef, and how to be a good captain," Pech said.
To keep the lobsters healthy, Pech inspects each one that Castillo catches. If it looks too small, he measures it. If the tail is shorter than the five-inch ruler, he throws the lobster back into the sea.
"We also free the biggest lobsters, weighing more than six pounds. The market doesn't pay their value. They are usually females, and they keep the species alive," he said.

When the lobster fishers throw a female back into the ocean, they not only protect the local population, they also support lobster populations in other parts of the Caribbean. The females lay millions of eggs that grow into larvae and float along ocean currents to new homes thousands of miles away.
After measuring and sorting the lobsters, the fishers send them to Cozumel to be sold. Occasionally, they keep a few for themselves, to be cooked on a hot skillet in a crowded cabana on the beach. It is a small indulgence for fishers who have nurtured the lobsters back into abundance in Maria Elena bay.
"The biggest threat to this place is us," Pech said. "We are in the lobsters' habitat. It is our livelihood, but we are invading a place we do not belong."

Officials at the highest levels are discussing the possibility of caving in on controlling the coronavirus and instead letting it run rampant throughout the United States until we reach "herd immunity," the point where the virus effectively runs out of people to infect. More than 6,200 scientists, health professionals, and research organizations say this is inhumane and have signed a memorandum rejecting herd immunity as a legitimate strategy.
Herd Immunity’s Unacceptable Toll<p>Resumption of normal life in the United States under a herd immunity approach would result in an enormous death toll by all estimates. Former CDC director Tom Frieden <a href="https://www.washingtonpost.com/opinions/tom-frieden-herd-immunity-wrong-solution-coronavirus/2020/10/16/acb4ae8a-0fe6-11eb-8074-0e943a91bf08_story.html" target="_blank">estimates</a> that another 500,000 people would have to die to achieve 60 percent herd immunity. "And that's the best-case scenario," Frieden wrote in a <em>Washington Post</em> op-ed. "The number of deaths to get there could be twice as high."</p><p>Frieden said that is the best-case scenario because no one really knows if the <a href="https://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/herd-immunity-and-coronavirus/art-20486808" target="_blank">actual percentage needed</a> to see the virus peter out is to have it <a href="https://thehill.com/opinion/healthcare/521834-covid-19-vaccine-barriers-efficacy-availability-and-acceptability" target="_blank" rel="noopener noreferrer">infect</a> more like <a href="https://www.washingtonpost.com/health/2020/08/31/herd-immunity-covid-19/" target="_blank" rel="noopener noreferrer">65, 70,</a> or even <a href="https://www.vox.com/21451282/herd-immunity-explained-covid-19-pandemic" target="_blank" rel="noopener noreferrer">75 percent</a> of the population. Even if immunity could be miraculously achieved at 50 percent, an estimate <a href="https://www.nature.com/articles/s41577-020-00451-5" target="_blank" rel="noopener noreferrer">published</a> in <em>Nature Reviews Immunology</em> places the range of sacrifice somewhere between 500,000 and 2.1 million deaths.</p><p>That makes it little wonder that Anthony Fauci, the most respected scientist advising the Trump administration on the pandemic, called herd immunity for the coronavirus "total nonsense." Fauci is backed up by the likes of National Institutes of Health Director Francis Collins, who said herd immunity is a "dangerous" and "fringe" component of epidemiology. Ashish Jha, dean of the Brown University School of Health <a href="https://www.bostonglobe.com/2020/10/20/nation/scores-mass-scientists-doctors-sign-open-letter-against-herd-immunity-proposal/?outputType=amp" target="_blank" rel="noopener noreferrer">called</a> herd immunity "junk science."</p><p>The head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, <a href="https://www.who.int/dg/speeches/detail/who-director-general-s-opening-remarks-at-the-media-briefing-on-covid-19---12-october-2020" target="_blank" rel="noopener noreferrer">said this month</a> that the only acceptable form of "herd immunity" is achieved through vaccination. "Herd immunity is achieved by protecting people from a virus, not by exposing them to it," the secretary general said. "Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic... Allowing a dangerous virus that we don't fully understand to run free is simply unethical. It's not an option."</p>
Herd Immunity Is the National De Facto Strategy<p>Somehow, none of that has culled herd immunity from being considered as a legitimate approach for fighting COVID-19. Rather, the Great Barrington Declaration has much in common with the Trump administration's approach to the coronavirus, which has led to more people dying from COVID-19 in the United States than in any other nation on Earth.</p><p>A de facto herd immunity approach is the only thing that can explain the push by governors of so many states to <a href="https://blog.ucsusa.org/derrick-jackson/the-push-to-relax-covid-19-protections-exposes-age-old-racial-wounds" target="_blank">reopen</a> bars, restaurants, beaches, bowling alleys, and gyms in states even as the virus has raged and case numbers have been increasing. It is the only thing that can explain the federal designation of meatpackers as essential workers and state demands that teachers go back into classrooms despite outbreaks and deaths related to those professions.</p><p>It also explains how so many of the nation's most respected scientific voices have been silenced. Despite the virus's current "uncontrolled spread" in 34 states and Puerto Rico, according to October 21 <a href="https://www.covidexitstrategy.org/" target="_blank" rel="noopener noreferrer">tracking</a> by CovidExistStrategy.org, the White House has pushed aside Fauci, Coronavirus Task Force Coordinator Deborah Birx, Surgeon General Jerome Adams, and Robert Redfield, the head of the Centers for Disease Prevention and Control.</p><p>In their place, the administration has handed the pandemic podium to <a href="https://www.washingtonpost.com/politics/trumps-den-of-dissent-inside-the-white-house-task-force-as-coronavirus-surges/2020/10/19/7ff8ee6a-0a6e-11eb-859b-f9c27abe638d_story.html?utm_campaign=wp_to_your_health&utm_medium=email&utm_source=newsletter&wpisrc=nl_tyh&wpmk=1&pwapi_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb29raWVuYW1lIjoid3BfY3J0aWQiLCJpc3MiOiJDYXJ0YSIsImNvb2tpZXZhbHVlIjoiNWE1ZDQ3N2M5YmJjMGYyNmNiMTViMmI0IiwidGFnIjoiNWY4ZGZhZmQ5ZDJmZGEwZWZiNGViMzQyIiwidXJsIjoiaHR0cHM6Ly93d3cud2FzaGluZ3RvbnBvc3QuY29tL3BvbGl0aWNzL3RydW1wcy1kZW4tb2YtZGlzc2VudC1pbnNpZGUtdGhlLXdoaXRlLWhvdXNlLXRhc2stZm9yY2UtYXMtY29yb25hdmlydXMtc3VyZ2VzLzIwMjAvMTAvMTkvN2ZmOGVlNmEtMGE2ZS0xMWViLTg1OWItZjljMjdhYmU2MzhkX3N0b3J5Lmh0bWw_dXRtX2NhbXBhaWduPXdwX3RvX3lvdXJfaGVhbHRoJnV0bV9tZWRpdW09ZW1haWwmdXRtX3NvdXJjZT1uZXdzbGV0dGVyJndwaXNyYz1ubF90eWgmd3Btaz0xIn0.MyoXrwQD-PwWqdbb70_JfrI_fxHO0be_O_tpTTMXBgE" target="_blank" rel="noopener noreferrer">Scott Atlas</a>, a radiologist and conservative pundit with <a href="https://blog.ucsusa.org/derrick-jackson/public-wants-science-based-policies-for-covid-19" target="_blank" rel="noopener noreferrer">no background</a> in infectious disease science or epidemiology in measuring disease prevalence. Inhumanely ignoring the more than half of U.S. adults having a pre-existing condition that could compromise them for COVID-19, he blithely praises herd immunity, <a href="https://blog.ucsusa.org/derrick-jackson/public-wants-science-based-policies-for-covid-19" target="_blank" rel="noopener noreferrer">saying,</a> "We can allow a lot of people to get infected. Those who are not at risk to die or have a serious hospital-requiring illness, we should be fine with letting them get infected."</p><p>He <a href="https://thehill.com/homenews/administration/521688-birx-confronted-pence-about-atlas" target="_blank" rel="noopener noreferrer">pooh-poohs</a> expanded testing, saying, "you are destroying the workforce." Twitter recently took down one of Atlas's tweets for falsely claiming, "Masks work? NO" and then lying that the WHO says widespread mask use is "not supported." The first sentence of the WHO's <a href="https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masks" target="_blank" rel="noopener noreferrer">webpage</a> on masks says, "Masks are a key measure to suppress the spread of COVID-19 and save lives."</p><p>Atlas denies that the White House has a "wide-open strategy of achieving herd immunity." But there's little doubt that the White House is wide open to the idea. Last week, Atlas <a href="https://www.foxnews.com/transcript/trump-adviser-calls-nbc-town-hall-brazen-display-of-media-duplicity" target="_blank" rel="noopener noreferrer">appeared</a> on Fox News <a href="https://www.wsj.com/articles/white-house-touts-document-calling-for-herd-immunity-approach-to-covid-19-crisis-11603051550" target="_blank" rel="noopener noreferrer">to say</a> the thrust of the Great Barrington Declaration "is exactly aligned with the president." That was seconded by a senior administration official who <a href="https://www.washingtonpost.com/health/covid-herd-immunity/2020/10/10/3910251c-0a60-11eb-859b-f9c27abe638d_story.html" target="_blank" rel="noopener noreferrer">told reporters</a> in a conference call that the Great Barrington Declaration "is endorsing what the president's policy has been for months."</p><p>The freezing out of scientists on the Coronavirus Task Force reached deep space levels this week (a metaphoric minus 455 degrees Fahrenheit), with multiple buckets of ice dumped on Fauci. Atlas diminished Fauci as "just one person" on the force, offering only a "limited approach." President Trump called Fauci a "disaster," <a href="https://www.washingtonpost.com/politics/trump-fauci-campaign-biden/2020/10/19/30b2fe58-1226-11eb-82af-864652063d61_story.html" target="_blank" rel="noopener noreferrer">claiming,</a> "People are tired of hearing Fauci and these idiots, all these idiots who got it wrong."</p>
Many Thousands of Lives Can Still Be Saved<p>Atlas's malpractice already merits his dismissal. He should be forced to step down because his disregard for science will surely lead to incalculable disaster if a herd immunity approach becomes official government policy. Calls for his ouster have already begun even from inside the task force. <a href="https://www.washingtonpost.com/politics/trumps-den-of-dissent-inside-the-white-house-task-force-as-coronavirus-surges/2020/10/19/7ff8ee6a-0a6e-11eb-859b-f9c27abe638d_story.html" target="_blank">According</a> to the <em>Washington Post</em>, Birx went to Vice President Mike Pence to suggest removing Atlas. All Pence reportedly did was ask Birx and Atlas to work out their problems on their own.</p><p>There is no time left for such discord within the task force and for discordant messages to come from the White House on how people should protect themselves from COVID-19. The thousands of scientists and public health professionals who signed the John Snow Memorandum say "it is critical to act decisively and urgently," to launch a "robust" response on the level of New Zealand, Vietnam, or Japan—all of which have shown success in containing the virus and keeping the numbers of cases and deaths relatively low.</p><p>The approach that has been proven effective starts with face coverings and social distancing and reducing the temptation we all will feel during the oncoming winter holidays to have extended family gatherings. Researchers from MIT and the Vancouver School of Economics <a href="https://www.medrxiv.org/content/10.1101/2020.05.27.20115139v6.full.pdf" target="_blank">estimate</a> in a working paper that, if the United States had established a national mask mandate in mid-March, between 19,000 and 47,000 lives could have been saved by the end of May. Now that the nation's death toll approaches a quarter million lives lost, and is <a href="https://covid19.healthdata.org/united-states-of-america?view=total-deaths&tab=trend" target="_blank" rel="noopener noreferrer">projected</a> to reach nearly 400,000 by February 1, according to the Institutes for Health Metrics and Evaluation at the University of Washington, the institute estimates we could avoid 74,000 new deaths with universal mask use.</p><p>Importantly, masks protect others, including the most vulnerable among us. This week, the <em>Washington Post</em> reported how coronavirus outbreaks among college students partying in unmasked packs in LaCrosse, Wisconsin was found to have <a href="https://www.washingtonpost.com/health/2020/10/21/la-crosse-wisconsin-covid-outbreak-nursing-home-deaths/?utm_campaign=wp_to_your_health&utm_medium=email&utm_source=newsletter&wpisrc=nl_tyh&wpmk=1&pwapi_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb29raWVuYW1lIjoid3BfY3J0aWQiLCJpc3MiOiJDYXJ0YSIsImNvb2tpZXZhbHVlIjoiNWE1ZDQ3N2M5YmJjMGYyNmNiMTViMmI0IiwidGFnIjoiNWY5MWU3YjU5ZDJmZGEwZWZiNTE3OGNmIiwidXJsIjoiaHR0cHM6Ly93d3cud2FzaGluZ3RvbnBvc3QuY29tL2hlYWx0aC8yMDIwLzEwLzIxL2xhLWNyb3NzZS13aXNjb25zaW4tY292aWQtb3V0YnJlYWstbnVyc2luZy1ob21lLWRlYXRocy8_dXRtX2NhbXBhaWduPXdwX3RvX3lvdXJfaGVhbHRoJnV0bV9tZWRpdW09ZW1haWwmdXRtX3NvdXJjZT1uZXdzbGV0dGVyJndwaXNyYz1ubF90eWgmd3Btaz0xIn0.6Ep-AvkJkNqGTE08UsekVlNWR01vYzQe-qg5BPruSQM" target="_blank" rel="noopener noreferrer">led to 19 deaths so far of people over the age of 60</a>.
