JAMESTOWN, R.I.

Even as a kid in the 1950s, James “Skip” Lazell knew that there were too many people living on the third rock from the sun. He got a vasectomy in 1960, when he was 21.

“Population has been a hot topic of mine for some time, but there’s very little we can do about it,” he said. “The economic system is a Ponzi scheme that requires growth, growth, growth to sell more and more products. More consumers are needed year after year. Overpopulation is the root cause of all of our problems, from excess carbon dioxide to global warming.”

His evolving concerns about human population and its impact have been formulated by his life’s work, plenty of discussion and much reading, such as the controversial bookThe Population Bomb, by Paul R. Ehrlich. The 1968 book sold millions. While Ehrlich’s doomsday scenario — the Stanford University biologist predicted hundreds of millions would starve to death in the 1970s — didn’t materialize, hunger is a major problem on a planet now inhabited by some 7.4 billion people. Our population is projected to exceed 9 billion by 2050. Our numbers are driving the planet’s sixth mass extinction.

While global population growth must be part of the conversation about sustaining the planet, it’s seldom discussed. Lazell has seen the issue sidelined for most of his 78 years.

“Sea-level rise, desertification and ocean acidification are linked to overpopulation,” he said. “Human-induced climate change is going to wipe out entire species and ecosystems. It’s likely going to end with catastrophic population decline."

Lazell, however, isn’t alone when it comes to talking about an issue that most of the world largely ignores. Geologist Walter Youngquist has called for a “greatly reduced” population as a critical element to the solution of natural-resource shortages.

In his 2016 paper, "Framework of the Future,'' Youngquist draws on his professional experience as a petroleum geologist and earth scientist to predict a grim future for the world’s people and its energy resources.

“It is doubtful the 7.4 billion people here now, and the billions more expected, can be sustainably supported in any decent standard of living beyond the time of the widespread use of fossil fuels,” he wrote. “This is the human dilemma. We have built a world based on fossil fuels ... and moving on to much less energy-dense and much less versatile alternative sources in the face of an ever-growing population is a challenge before us. ... If there is a solution to this problem it is a greatly reduced and much less affluent population.”

Youngquist and the Virginia-based organization Negative Population Growth both have noted the conspicuous absence of any official U.S. population policy. Author Alan Weisman’s 2013 book, Countdown, looked at how many peoplethat the planet can sustain. Lazell believes thatit’s a billion. The longtime/part-time Rhode Islander is concerned that the crush of humanity will wipe out many of the creatures he has spent his life finding, studying and conserving.

“We’re pretty smart, but we need leadership to get interested in overpopulation,” Lazell said. “The United States devours the most, and much of the rest of the world wants to live like Americans. Our consumption level is unsustainable.”


ecoRI News visited with Lazell last month at his modest home on Swinburne Street, Jamestown, a house he bought in the late 1960s. We sat in his living room for more than an hour talking about the natural world and the many pressures squeezing it. While he has long been concerned with human population, his life’s real passion, animals, most notably reptiles and amphibians, also began when Lazell was a child.

As a youngster, Lazell spent hours reading and studying his world atlas. His interest in geography often focused on islands. His scientific niche naturally grew into “island biogeography.” In its Dec. 8, 1957 edition, the Philadelphia Inquirer magazine featured an article about the 18-year-old naturalist and how he had, among other things, recently captured crocodiles in Jamaica.

Lazell was born in New York City and grew up in suburban Philadelphia. His accent, however, has been softened by boyhood summers spent with family in Jackson, Miss. But Rhode Island, specifically Conanicut Island (Jamestown), has served as his summer and fall base for decades.

Lazell earned a Ph.D. from the University of Rhode Island — he also has graduate degrees in biology and zoology from Harvard University and the University of Illinois. In 1988, in Jamestown, a friend’s mother introduced Lazell to a Chinese-born woman, Wenhua Lu, who would become his wife. Wenhua, who also earned a Ph.D. from URI, married Lazell in 1992. They don’t have any children, for obvious reasons.

While zoologist Lazell focused on amphibians and reptiles — his thesis was on lizards of the West Indies — his 62-year-old wife is an entomologist with a keen interest in beetles.

When he was 17, the Philadelphia Zoo paid for Lazell to go to the West Indies to collect specimens. It’s where his doctoral work on Anolis, a genus of iguanian lizards, first came into focus. He returned a year later on another zoo-funded trip.

In fact, Lazell visited the West Indies every year from 1957 to 2014, making his last visit when he was 75. His favorite island there is Dominica.

For this work researching clouded Anole on the uninhabited West Indies island of Redonda, Lazell rented a boat, was given a compass and was wished good luck. He loved the experience, a wide grin formed on his face when he recalled the tale. His 30 years of work on Guana Island reportedly produced the most comprehensive, long-term record of the natural history of a Caribbean island.

Iguanas, salamanders and crocodiles, however, haven’t consumed all of Lazell’s professional time. He first recognized the potential for successful reintroduction of flamingos to the salt ponds of Anegada in the early 1980s.

He has been published in scientific journals more than 200 times; he’s discovered some 30 new species and rediscovered some of the planet’s rarest ones. In 1985, Lazell made Rhode Island’s first official recording of spring salamanders, commonly called gyros, in Foster.

His 1976 book, This Broken Archipelago: Cape Cod and the Islands, Amphibians, and Reptiles, has detailed chapters on 38 species of frogs, salamanders, toads, turtles and snakes, their natural history, and how they got there. His 2005 book,  Island: Fact and Theory in Nature, describes Guana’s flora and fauna against the backdrop of islands worldwide and their ecology, evolution and conservation.

The longtime naturalist worked with the late Roger Conant, a herpetologist, author and educator who wrote one of the first comprehensive field guides for North American reptiles, in 1958. He also was director emeritus of the Philadelphia Zoo.

Lazell studied with the late Ernest Edward Williams, a noted Harvard University herpetologist. Before founding a Jamestown-based nonprofit in 1980, Lazell had stints with The Nature Conservancy and the Audubon Society. He taught biology at the Palfrey Street School in Watertown, Mass.

He founded the The Conservation Agency to work globally to provide and publish scientific data “contributing to the protection of biodiversity and promoting sustainable relationships with valued wildlife.” Lazell was the organization’s president until a few years ago, when his former Palfrey Street School student Numi Mitchell took the reins. He said the founding of The Conservation Agency was the “biggest thrill” of his career.

Now 78, Lazell, who is recovering from open-heart surgery, still speaks enthusiastically and passionately about his life’s work and the wondrous natural world in which we live. He and his wife will return to Jackson, Miss., to his late parents' home, in early November as usual, after they enjoy New England’s fall foliage and crisp air.

His proudest accomplishment, though, may be this:

“I was the only person to be a full-time employee at both Yale and Harvard with a full beard, earring and tattoo,” he said with a smile.

Frank Carini: Human overpopulation's assault on the environment

Via ecoRI News (ecori.org)

Lost in the discussion about climate change — at least the snippets of it not drowned out by the air horns of special interests — is the issue of overpopulation, arguably the main reason that  the planet is heating up, the oceans are acidifying and the atmosphere is wheezing.

Our sheer numbers are mostly a threat to, well, ourselves. The planet will recover; we won’t if we fail to take real action. Our most recent response — a full-on assault of women’s reproductive rights — doesn’t leave our children’s children much hope.

Sensing this blatant disregard for their future, a group of 21 kids, in 2015, filed a climate lawsuit against the federal government. It’s moving forward. In the lawsuit, the young plaintiffs have accused the federal government of violating their constitutional rights by knowing about the climate impacts of burning fossil fuels and supporting the development of fossil-fuel production anyway.

The residents of Burrillville, R.I., can relate.

Meanwhile, many of the adults elected to lead us forward act like spoiled brats. In the face of overwhelming scientific proof — never mind common sense — that human activities are changing the climate and punishing the natural resources that sustain us and all other life, they dismiss the importance of family planning and reproductive heath to push ideology.

Tom Price, current secretary of the Department of Health and Human Services, hates birth control. As a member of Congress, he voted to terminate the program that subsidizes contraception for low-income women. He voted against a law barring employers from firing women for using contraception. He rages against the Affordable Care Act (ACA) requirement that insurance plans cover contraception without a co-pay.

He told ThinkProgress in 2012 that there are no women who struggle to afford birth control and that the ACA’s contraceptive mandate is wrong. “Bring me one woman who has been left behind. Bring me one. There’s not one,” he is quoted. “The fact of the matter is, this is a trampling of religious freedom and religious liberty in this country.”

This widely shared heavenly worldview is helping trample the life out of this planet. It’s a big middle finger to the future.

Consider this staggering fact: human population grew from 1.6 billion to 6.1 billion during the course of the 20th Century, according to the United Nations Population Fund. It took 199,900 years for the population to reach 1.6 billion, and then, in a blink of a century, 4.5 billion more people were added.

The worldwide population, now at 7.4 billion, is projected to reach 9.7 billion by 2050. We need intelligent conversations — not intelligent design — about our population, to eschew escalating wars fought over natural resources and to avoid increased pain and suffering.

Climate change, or if you prefer the label global warming, is really just about numbers — ours. It’s a simple math problem. But the issue of human population is never debated during presidential campaigns or discussed by cable TV’s talking heads.

Population, climate change and consumption are inextricably linked in their collective global environmental impact, according to the Sierra Club’s Global Population and Environment Program.

The Worldwatch Institute says the two overriding challenges facing mankind are to mitigate climate change and slow population growth.

“Success on these two fronts would make other challenges, such as reversing the deforestation of Earth, stabilizing water tables, and protecting plant and animal diversity, much more manageable,” according to the Washington, D.C.-based organization. “If we cannot stabilize climate and we cannot stabilize population, there is not an ecosystem on Earth that we can save.”

Addressing these two interconnected issues starts with improving the health of women and children, especially in developing nations. By reducing poverty and infant mortality, increasing female access to human rights, such as economic opportunity, education and health care — funding that the White House wants to cut because some of the organizations helping to improve the lives of poor women and girls also provide abortions — educating women about birth-control options and ensuring access to family planning services, women worldwide would have stronger voices.

Knowledge, after all, is power, but we seem determined to curtail education, as we relentlessly attack climate science and evolution, and spout rubbish about the Environmental Protection Agency generating “propaganda” and “brainwashing” children.

If he isn’t already, Sen. James Inhofe, R-Okla.., should be named as a defendant in the kids’ climate lawsuit. The senator who recently spewed that brainwashing garbage received $465,950 from the oil and gas industry during the past five years to help fatten his campaign coffers.

Humans continue the geo-engineering of the natural world to sustain our unsustainable numbers. The bough will eventually break.

More than two centuries ago, English scholar Thomas Malthus published ''An Essay on the Principle of Population''. In his writing he noted that human population tends to grow geometrically, while the resources available to support it tend to grow arithmetically. Under these conditions, he wrote that human population will inevitably outgrow the supply of food. He predicted that population growth would lead to degradation of the land, and eventually massive famine, disease and war.

Improvements in agriculture and the Industrial Revolution postponed the disaster Malthus thought was imminent, although much of what he predicted as happened, just not in one fell swoop.

Now, 219 years later, can we again tech our way out of the numerous impacts our rapidly growing population has and will create?

If so, it will likely come at the cost of diversity, and a considerable price has already been extracted. It also will likely expand the already-too-wide gap that separates the wealthy from the poor.

Simply discussing the issue of population is taboo, and many of the conversations that are held inevitably veer toward population control and China’s since-lax one-child policy.

Ignoring the problem won’t solve it. We need to have grown-up discussions about reproductive health. We need to address public health and population at all levels of government. After all, humans are the main force behind environmental pollution.

In the United States, at least, these vital conversations are muted by politicians who clap their tiny hands and get all giddy about rolling back laws enacted to protect public health and the environment. God forbid if the words “penis” or “vagina” are mentioned in a classroom.

A voluntary family-planning program in Iran helped drop the highest rate of population growth in the country’s history to replacement level a year faster than China’s compulsory one-child policy. The program subsidizes vasectomies, offers free condoms and affordable contraceptives, and supports countrywide education on sexual health and family planning.

Iran’s collection of spoiled brats, which, like here, consists mainly of older, whiny men, wants to defund the program.

It seems the “leaders” of these two countries have more in common than they know.
