True Environmentalists Should Prioritize Economic Prosperity

Prosperity frees people to protect the environment.

The COVID-19 pandemic and the accompanying lockdowns reduced global CO2 emissions by 7 percent last year. Some environmentalists, such as the University College London professor Mariana Mazzucato, have thus wondered about the feasibility of future “climate lockdowns … to tackle a climate emergency.” Yet even if we ignore the negative consequences of the lockdowns on broader health outcomes and human psychology, Mazzucato appears to fail to account for the well-known correlation between economic prosperity and environmental quality.

Lockdowns have contributed to around 100 million people, most of them living in the developing world, sliding back into extreme poverty. While they may have lowered the CO2 emissions in the short term, by increasing absolute poverty, the lockdowns may cause massive environmental destruction in the long term. Simply put, people can afford to care about the environment only when they have enough income to cover their basic needs. If their survival depends on killing an endangered animal or cutting down a rare tree, then so be it.

The Environmental Kuznets Curve (EKC) hypothesis posits that environmental damage increases in tandem with economic growth, but only until a certain level of income is reached. Once people are wealthy enough not to have to worry about day-to-day survival, environmental degradation stops, and ecosystems begin to recover. The environmental scientist Jesse H. Ausubel, for example, suggests that once a nation achieves a GDP per capita of $6,200 (in 2021 dollars), deforestation stops or afforestation occurs.

In fact, forest coverage is growing in China, Russia, India, and Vietnam – all emerging economies that reached the $6,200-mark. The curve is even clearer in wealthy regions like North America and Europe – both of which have more trees today than they did a century ago. The UK, for example, has more than doubled its forest area in the last 100 years. Conversely, deforestation continues in poor African and Latin American countries. Scientists have found that the EKC holds true in all manner of environmental domains, including water pollution, carbon dioxide emissions, nitrogen, sulphur, and biodiversity.

While it is too early to gauge the impact of the lockdowns on forest coverage, the lockdowns have already wreaked havoc on endangered species and protected habitats in the developing world. In Kenya, the killing of giraffes has skyrocketed. Given that a tonne of giraffe meat is worth about $1,000 (i.e., almost seven months of the average Kenyan salary), it is unsurprising that desperate locals have resorted to slaughtering the endangered animal. Kenya’s Mara Elephant Project also recorded that illegal logging in the region peaked in the months following the first lockdown. In Botswana, government workers had to evacuate dozens of critically endangered black rhinos from the Okavango Delta after six of the animals were found dead after the lockdowns were implemented. 

In Colombia, the poaching of endangered pumas and jaguars has also rapidly increased. In India, tiger numbers were steady, as incomes have increased, for the last two decades. But, since the lockdowns were imposed, various reports have highlighted an upsurge in tiger poaching and illegal hunting. Similarly, in India’s Western Bengal region, where over a million jobs have been lost due to the lockdowns, the local authorities have reported the first-ever instance of illegal ivory poaching in the region. The problem of illegal poaching is exacerbated by the fact that park rangers in some countries have been left without work and income. The animals, in other words, have lost their human protectors.

The World Economic Forum recently acknowledged that the significant increase in bushmeat harvesting and wildlife trafficking in Africa “is directly linked to COVID-19-related lockdowns.” Similarly, the UK-based wildlife charity called People’s Trust for Endangered Species has warned that “unintended consequences” of lockdowns could undo “decades of work” devoted to animal protection.

Fortunately for mother nature, as economies begin to recover from the government-mandated lockdowns, the number of people who rely on illegal activities will decrease, and biodiversity will slowly recover. However, the EKC and the wretched impact of lockdowns on poverty and biodiversity teaches us an important lesson – true environmentalists should seek to prioritize economic growth, not lower it. Poverty-reducing policies, such as strong property rights, freedom to trade, lower regulation, and few burdensome taxes, as shown annually in the Fraser Institute’s Economic Freedom of the World Report, remain some of the most reliable ways of raising economic prosperity for all.

In conclusion, poor people depend on mother nature to survive. Rich people, in contrast, can decouple themselves from the environment, protect wildlife for future generations, and return vast swathes of land to nature. Now, what environmentalist wouldn’t want that?

Saving Water Even as We Grow

Amid record drought, communities in the American West are finding ways to do more with less water.

Summary: Amid record drought, communities in the American West are finding ways to use far less water. This article examines how innovations such as wastewater recycling, desalination, and water markets conserve water while allowing the West to prosper and grow.


The American West is in the grips of its worst drought in more than a millennium. Reservoir levels in some areas have dipped to all-time lows. The shortages are especially dire in the Colorado River Basin, which supplies water to 40 million people and irrigates four million acres of farmland.

There are plenty of gloomy headlines on the West’s water crisis. But beyond the front page is a lesser-known story of remarkable adaptation: over the past few decades, western communities have found ways to use far less water, even as populations grow and economic output increases. It’s a testament to the ability of humans to respond to water scarcity, and it illustrates what more is needed to enable continued adaptation in the future.

Consider Las Vegas. Since the drought began two decades ago, the city has cut per capita water use by half. Total water use has fallen by 26 billion gallons since 2002, even as its population has grown by 800,000 residents. Or take Phoenix, another fast-growing metropolitan area. Since 1980, the city’s population has more than doubled, yet its total water use has declined by one-third

The same is true in much of the American West. Since 2000, Albuquerque’s per capita water use has fallen 48 percent; Denver’s by 38 percent; and Los Angeles’ by 29 percent. San Diego’s water use has plummeted from nearly 220 gallons a day per person in 2007 to less than 140 gallons per person. Total water use in the city is down 40 percent. A recent study of 20 western cities found that population growth from 2000 to 2015 increased by an average of 21 percent, while total water use declined by an average of 19 percent. 

How has this happened? In his book Water Is for Fighting Over: And Other Myths about Water in the West, the writer John Fleck explores the impressive ability of people to adapt to water scarcity without sacrificing economic growth. When people have less water, Fleck writes, they find ways to use water more efficiently. Often, that’s through stormwater capture, wastewater recycling, aquifer storage, lawn buyback programs, and other innovations.

In San Diego, city officials have invested in desalination plants, sewage recycling, raising dams, and other water-saving measures. A new wastewater recycling project is expected to meet roughly half of the city’s drinking water needs by 2035. In Nevada, water managers have implemented “cash for grass” programs, which offer rebates to businesses and residents who tear out lawns and replace them with water-efficient alternatives. The program has resulted in significant per capita water-use reductions, according to the Southern Nevada Water Authority. 

Modern cities, it turns out, are quite water efficient, especially when compared to irrigated thirsty desert croplands. In Arizona, building houses to accommodate a growing population has resulted, somewhat counterintuitively, in significant water savings in the region. By one estimate, converting 100 acres of Arizona cotton fields into subdivisions with quarter-acre lots can cut water use by roughly a third. 

Prices also play a role. Water prices in San Diego reached as high as $1,736 an acre-foot  (enough water to cover an acre of land, about 326,000 gallons) last year, up from $620 in 2007, encouraging conservation and spurring water-saving innovations. In other parts of the West, however, water prices remain low despite recent drought conditions. Salt Lake City, for instance, has among the lowest water prices of major U.S. cities; it also consumes more water than other desert cities. 

The agricultural sector, which uses roughly 80 percent of all water in the West, is also conserving water. In California, for example, farm water use in 2015 was 14 percent less than in 1980, while economic output from farming was up 38 percent. This is due in large part to rising crop yields. Farmers can now grow more crops on less land while using less water, enabling them to transfer some of that saved water to cities or, in some cases, to increase environmental flows for fish and wildlife habitat.

This adaptation story is one to celebrate and sustain. Contrary to apocalyptic media reports, western communities have decoupled water consumption from economic growth. But despite these recent successes, more water conservation is needed in response to today’s prolonged drought conditions.

Tapping water markets is one way to do so. Markets allow users to move water from lower-value to higher-value uses, thereby encouraging conservation and promoting more efficient use. In practice, however, a variety of legal and policy barriers can prevent win-win water trades from occurring. Reducing barriers to water markets is crucial to enabling further adaptations to drought in western states.

The American West has a remarkable ability to adapt to water scarcity. Current drought conditions are bad, but they are likely to spur even more water-saving innovations and policy reforms in the future. Ultimately, that ingenuity will enable people to conserve water while allowing the West to continue to prosper.

How Humanity Is Illuminating Life

The sharpest naturalists in history may have been able to identify a few hundred species in the field. Today, a ten-year-old with a smartphone app can identify millions.

Summary: This article explores how humanity has advanced its knowledge of biodiversity over time, from folk wisdom to modern databases. It highlights how technology has made information about life on Earth accessible to everyone and argues we should be optimistic about the future of taxonomy and conservation.


Alone in the forest, the modern person might find it difficult to identify a beech tree. Compared to indigenous shamans who forage thousands of medicinal plants, we are deeply disconnected from nature. But even if our personal understanding of nature is in decline, as a species, we’ve never known more about the natural world.

The fact is, while it is valuable, indigenous knowledge is often limited to the local area, difficult to distinguish from myth and ritual, and, if passed on orally, easy to lose. Literate naturalists faced similar problems. Aristotle recorded many species in writing, but much of his work was lost. Most traditional written research that survived to modern times is narrow in scope, disorganized, and spread throughout obscure tomes.

Over the last few centuries, humanity has transformed this scattered folk knowledge into a systematic account of life on Earth. And over the last few decades, we’ve made that knowledge accessible to everyone. After years of experience, the sharpest naturalists in history may have been able to identify a few hundred species in the field. Today, a ten-year-old with a smartphone app can identify millions with better accuracy.

The process began with Carl Linnaeus (1707-1778), a Swedish botanist whose magnum opus, Systema Naturae, forms the foundation of modern taxonomy. Linnaeus used a rank-based system to order life based on its physical structure. His system of kingdoms, classes, orders, families, genera, and species is still used today, though it has been significantly revised and expanded. By 1758, Linnaeus had cataloged and categorized around ten thousand species. As of 2020, that list had grown to over two million.

Our knowledge of life has grown deeper as well as broader. With little understanding of evolution or microbiology, Linnaeus only identified two kingdoms of life: plants and animals. Now, we know of seven (Plantae, Protozoa, Animalia, Chromista, Fungi, Bacteria, and Archaea), plus the strange world of non-cellular life (viruses and prions).

This knowledge is also becoming more reliable. In the past, since information about biodiversity was dispersed among many organizations and professions, organisms were often recorded multiple times under different names. In 2011, University of Hawaii biologist Camilo Mora estimated that 17.9% of species names were synonyms for the same species.

That is beginning to change thanks to the internet, which gave rise to global databases that attempt to centralize and standardize information about biodiversity. These archives compile taxonomic synonyms under a single entry and link them with the common names of species (i.e., Ictalurus furcatus with blue catfish), meaning they are useful for both scientists and laypeople.

Some are of these databases are specialized – MycoBank deals with Fungi, FishBase with fish, and so on. Others are more general. The Catalogue of Life, for example, uses data from specialized databases to create a universal record. Since 2000, the Catalogue of Life has grown from 220,000 species to over 2 million. Using their website, you can access information about nearly any discovered lifeform with a single search.

Other projects have even loftier goals. The International Barcode of Life (iBOL) is creating a library of “DNA barcodes,” or short sections of DNA that are unique to each species. Using DNA records eliminates the risk of taxonomic synonyms and provides a fool-proof way to identify specimens found in the wild. iBOL has already scanned 500,000 species and plans to scan another two million by 2026.

By organizing our knowledge about life, these databases promise to bring taxonomy into a golden age of reliability and accessibility. Information that once existed only in the heads of experts and rotting scrolls is now in reach of anyone with a computer.

These advances couldn’t have come at a better time. Though we don’t know the state of microbial life, plant and animal biodiversity is in decline, meaning we need to act quickly. If a species goes extinct before we identify and sample it, whatever secrets its genetics contained may be lost forever. But if a species goes extinct after it has been sampled, it could be possible to bring it back from the dead.

The number of species that die out before we discover them depends on three factors: the discovery rate, the extinction rate, and the total number of species in existence. University of Auckland biologist Mark Costello has calculated that the rate of species discovery far outpaces the extinction rate. So, at a minimum, we should expect to identify most species on Earth before they go extinct. How many we end up recording depends on how many species exist, a question that has eluded scientists so far.

To ensure we discover as much life as possible, we should decrease the extinction rate and increase the discovery rate. And of course, it is not enough to have many types of life; we should also ensure each species can thrive in great numbers. The good news is that globally, deforestation is slowing, and the wilderness is returning. Those trends, combined with successful conservation efforts, have caused many previously endangered species to rebound.

This renewal isn’t limited to protected areas. Recent research in Spain has shown that after humans retreated from nature and let their farms grow into forests, animals became bolder and expanded their habitats into unprotected land. Rather than hiding in remote cliffs, golden eagles began nesting in lower-altitude trees. Wolves, bears, and boars expanded in numbers and are now encroaching on human settlements. The European otter, once considered an “upper-river specialist,” moved downstream and even colonized coastal areas and golf courses.

In other words, we are discovering that nature is resilient. When we remove our yoke from the natural world, wildlife recovers.

Things are looking good on the discovery front as well. The ecologist Lucas Joppa found that since 1800, the number of species discovered per year in all groups except for birds is increasing exponentially alongside the number of taxonomists. However, the number of species the average taxonomist describes is decreasing, meaning we may need ever more taxonomists to keep up the pace of discovery.

Luckily, technology is giving everyone the ability to contribute to taxonomy. iNaturalist, a social network developed at UC Berkeley, allows users to upload photographs of organisms to be identified by the entire naturalist community or by a machine learning algorithm trained on previous observations.

To date, the app has generated 78 million observations, many of which contribute to user-generated projects that tackle everything from tracking invasive species to photographing previously undocumented living specimens. The app isn’t just a fad, either. Since 2012, the number of iNaturalist users and observations has doubled every year.

Whether they are identifying the weeds in their gardens, tracking invasive beetles, or counting seals in Antarctica, citizen scientists promise to bring our knowledge of the natural world to ever greater heights.

Post-industrial humans may be separating from nature. We spend very little time in it and, compared to our nomadic ancestors, we scarcely rely on it. But by removing ourselves from the natural world, we are giving other creatures the chance to thrive, and whatever connection we have lost is being replaced with knowledge that is just as spectacular.
