Ohio State scientist Rattan Lal wins World Food Prize
June 12, 2020
COLUMBUS, Ohio — A soil scientist at Ohio State University whose research spans five continents was awarded this year’s World Food Prize for increasing the global food supply by helping small farmers improve their soil.
Over five decades, Rattan Lal, a distinguished university professor in the College of Food, Agricultural and Environmental Sciences, has reduced hunger by pioneering agricultural methods across the globe that not only restore degraded soil but also reduce global warming.
“Every year we are astounded by the quality of nominations for the prize, but Dr. Lal’s stellar work on management and conservation of agriculture’s most cherished natural resource, the soil, set him apart,” said Gebisa Ejeta, chair of the World Food Prize Selection Committee and 2009 recipient of the award issued by the World Food Prize Foundation based in Iowa.
“The impact of his research and advocacy on sustainability of agriculture and the environment cannot be overstressed,” Ejeta said.
Big impact
Beginning in the 1970s with his research in West Africa, Lal has discovered ways to reduce deforestation, control soil erosion, and enrich soil by managing a critical element in the soil: organic carbon.
His research has provided the scientific foundation to show that soil can not only solve the global challenge of food insecurity but also global warming. As the 2020 winner of the World Food Prize announced via webcast, Lal was awarded $250,000, which he will donate for future soil research and education. He is the first at Ohio State to receive the award.
“It is a privilege and honor to be of service to the many small farmers from around the world because I was one of them. They are stewards of the land. They are the ones with the tremendous challenge of feeding the world,” said Lal, who is founding director of the Carbon Management and Sequestration Center in CFAES at Ohio State.
Lal was listed by Thomson Reuters as among the top 1% of the most-cited scientists in agriculture for the 2014 to 2019 period and among the world’s most influential scientific minds in 2015.
A faculty member at Ohio State for 33 years, Lal was recognized for his contributions to the Intergovernmental Panel on Climate Change, which shared the 2007 Nobel Peace Prize with former U.S. Vice President Al Gore.
In 2019, Lal became the first soil scientist and the first person at Ohio State to receive the Japan Prize. A year before, he received the 2018 World Agriculture Prize and the 2018 Glinka World Soil Prize.
Life story
Beyond Lal’s worldwide contributions to soil health, one of his more remarkable aspects is the trajectory of his life. At age 5, he and his family left west Punjab, resettling in northern India, as refugees, in a village without electricity. There, he and his family worked a small 7-acre farm using oxen. Drought was frequent and temperatures brutally hot. On that farm, Lal came to realize that soil can play a critical role in creating a buffer against harsh conditions by holding onto water and nutrients.
While his elder siblings ran the family farm, Lal was the only one who had a chance to go to school, the only one in his family who learned to read and write. Making the most of that opportunity, Lal pursued the education and research that have allowed him to have an impact on how policy makers and farmers across the world think about and treat soil.
In the 1990s, Lal co-wrote the first documented report showing how restoring degraded soil by taking in carbon dioxide from the air not only improved the soil but also defended against rising levels of carbon dioxide.
In the decades before and since, Lal has promoted agricultural practices that optimize the soil’s ability to act as a sponge, soaking up carbon dioxide in the air through photosynthesis, and returning it to the soil when the plant decomposes. This in turn enriches the soil, making it more conducive to growing crops.
His work
The techniques Lal has advocated include eliminating plowing, retaining crop residue left after harvest, planting cover crops, minimizing the use of chemical fertilizers, and setting aside land and water for nature, rather than for agriculture or other purposes. Each practice comes at low cost, affordable even to farmers in the developing world.
The agricultural practices Lal has promoted are now at the heart of efforts to improve agriculture systems in the tropics and globally. Lal’s research began in 1963 with studies on low corn production in India.
Working with farmers in Asia, Africa, and Latin America in the 1970s and 1980s, Lal introduced changes to the common practice of cutting down and burning swaths of trees, causing erosion of valuable topsoil. During a 10-year project that began in 2000, Lal worked with farm communities across India to promote adoption of best management practices to enhance and sustain production.
Along with his research, Lal has partnered with international and national policy makers as well as industries to increase carbon in the soil and prevent fields from eroding, keeping both sediment and chemicals from getting into nearby waterways.
All of Lal’s work has been guided by one principle: The health of soil, plants, animals, people, and the environment all depend on each other. “When the health of soil degrades, it creates a domino effect,” Lal said. “Restoring soil health is essential to restoring human health.”
New Study Shows More Than 1,000 Tons of Plastic Dust Lands on U.S. National Parks Each Year

Plastic dust is blowing into U.S. national parks—more than 1000 tons each year
By Erik Stokstad Jun. 11, 2020 , 5:30 PM
Remote wilderness areas and national parks in the western United States are getting a dusting of plastic every year, perhaps 1000 tons or more, according to a new study. Up to one-quarter of the microscopic pieces of plastic—which come from carpets, clothing, and even spray paint—may originate in storms passing over nearby cities, whereas the rest likely comes from farther flung locations. The findings, the first to tease apart geographic origins, add to mounting evidence that such microplastic pollution is common worldwide.
“We created something that won’t go away,” says Janice Brahney, a biogeochemist at Utah State University and lead author on the new paper. “It’s now circulating around the globe.”
Brahney didn’t set out to track plastic pollution. Instead, she wanted to study how wind-blown dust delivers nutrients to ecosystems. So, she set up a pilot study with the National Atmospheric Deposition Program to collect such dust at a network of weather stations usually used to sample rainwater across the United States, mostly in remote locations.
Looking at samples from 11 remote areas in the western United States, including the Grand Canyon and Joshua Tree National Park, Brahney noticed brightly colored fragments under the microscope. “I realized that I was looking at deposition of plastics, which was really shocking.” Brahney didn’t have funding to study microplastic pollution, so she did the analysis on her own time, spending a “very long and stressful year” of evenings and weekends counting nearly 15,000 tiny pieces—most of them less than one-third the width of a human hair.
Brahney found a lot of tiny fibers, likely from clothes, carpets, and other textiles. She also found minuscule particles, about 30% of which were brightly colored spheres. Smaller than the plastic microbeads that have been used in cosmetics and other personal care products, the spheres are components of paints that might be released to the atmosphere during spray painting, she says.
Chelsea Rochman, an ecologist at the University of Toronto who studies microplastics, calls that finding “striking.” The paints are “a whole new source that hasn’t really been discussed before.”
The remaining 70% of the particles were harder to classify. So Brahney and a colleague turned to a technique called Fourier transform infrared spectroscopy to analyze those particles and the fibers. It showed that the samples contained on average 4% plastic. “That number blew us away,” says Brahney, who had expected less than 1%.
After running the numbers, Brahney and her colleagues estimated that about 132 pieces of microplastic land on every square meter of wilderness each day. That adds up to more than 1000 tons of plastic per year across national parks and other protected areas of the western United States—the equivalent of 300 million plastic water bottles, they report today in Science. Other studies have found similar amounts of microplastics in remote locations, including Europe’s Pyrenees Mountains and in Arctic. But the new study has far more detailed data, which helped Brahney in her next step: figuring out where the plastic was coming from.
To do that, Brahney used a weather model to identify the paths of storms for 48 hours before they reached the sampling sites. Storms that had passed over or near large cities carried more microplastic than other storms, she found. The largest amounts were carried in storms that had passed over Denver; these storms deposited 14 times as much microplastic in the Rocky Mountain National Park sample station as storms that came from other directions. The pieces of microplastic were also larger than those that settled out of the air in dry weather, suggesting the strong winds of the storms had picked up the heavier pieces.
Brahney says most of the plastic is likely coming from more distant locations, brought in via high-altitude winds rather than regional rainstorms. About 75% of the plastic was deposited during dry rather than rainy weather. Those pieces tended to be smaller—the size of extremely fine dust, which can travel for thousands of kilometers. In addition, the deposition patterns showed some influence of the jet stream. Higher elevation sites also tended to have more microplastic, further implying that the particles move high in the atmosphere—and may circulate globally.
Rochman calls this piece of the study the “wow” part. Trying to understand the patterns and processes of how microplastics move around the globe is only just beginning, she says.
Brahney is now working with atmospheric scientists who specialize in dust transport to study such questions as how plastic particles move through the atmosphere, where they might come from, and how much could be in the air. Much of this microplastic might have been circulating for years, if not decades, she says. The particles may have first settled in farm fields, or deserts, or the ocean and then have been picked up again by winds as part of a global “plastic cycle.”

Climate change threatens drinking water quality across the Great Lakes

“Do Not Drink/Do Not Boil” is not what anyone wants to hear about their city’s tap water. But the combined effects of climate change and degraded water quality could make such warnings more frequent across the Great Lakes region.
A preview occurred on July 31, 2014, when a nasty green slime – properly known as a harmful algal bloom, or HAB – developed in the western basin of Lake Erie. Before long it had overwhelmed the Toledo Water Intake Crib, which provides drinking water to nearly 500,000 people in and around the city.
Tests revealed that the algae was producing microcystin, a sometimes deadly liver toxin and suspected carcinogen. Unlike some other toxins, microcystin can’t be rendered harmless by boiling. So the city issued a “Do Not Drink/Do Not Boil” order that set off a three-day crisis.
Local stores soon ran out of bottled water. Ohio’s governor declared a state of emergency, and the National Guard was called in to provide safe drinking water until the system could be flushed and treatment facilities brought back on line.
The culprit was a combination of high nutrient pollution – nitrogen and phosphorus, which stimulate the growth of algae – from sewage, agriculture and suburban runoff, and high water temperatures linked to climate change. This event showed that even in regions with resources as vast as the Great Lakes, water supplies are vulnerable to these kinds of man-made threats.
As Midwesterners working in the fields of urban environmental health and climate and environmental science, we believe more crises like Toledo’s could lie ahead if the region doesn’t address looming threats to drinking water quality.
Vast and abused
The Great Lakes together hold 20% of the world’s surface freshwater – more than enough to provide drinking water to over 48 million people from Duluth to Chicago, Detroit, Cleveland and Toronto. But human impacts have severely harmed this precious and vital resource.
In 1970, after a century of urbanization and industrialization around the Great Lakes, water quality was severely degraded. Factories were allowed to dump waste into waterways rather than treating it. Inadequate sewer systems often sent raw sewage into rivers and lakes, fouling the water and causing algal blooms.
Problems like these helped spur two major steps in 1972: passage of the U.S. Clean Water Act, and adoption of the Great Lakes Water Quality Agreement between the United States and Canada. Since then, many industries have been cleaned up or shut down. Sewer systems are being redesigned, albeit slowly and at great cost.
The resulting cuts in nutrient and wastewater pollution have brought a quick decline in HABs – especially in Lake Erie, the Great Lake with the most densely populated shoreline. But new problems have emerged, due partly to shortcomings in those laws and agreements, combined with the growing effects of climate change.
Warmer and wetter
Climate change is profoundly altering many factors that affect life in the Great Lakes region. The most immediate impacts of recent climate change have been on precipitation, lake levels and water temperatures.
Annual precipitation in the region has increased by about 5 inches over the past century. Changes in the past five years alone – the hottest five years in recorded history – have been particularly dramatic, with a series of extreme rainfall events bringing extremely high and rapidly varying water levels to the Great Lakes.
Record high precipitation in 2019 caused flooding, property damage and beachfront losses in a number of coastal communities. Precipitation in 2020 is projected to be equally high, if not higher. Some of this is due to natural variability, but certainly some is due to climate change.
Another clear impact of climate change is a general warming of all five Great Lakes, particularly in the springtime. The temperature increase is modest and varies from year to year and place to place, but is consistent overall with records of warming throughout the region.
Lake levels continue to reach record highs or near-record highs across the basin. What problems does this cause?
Coastal erosion
Flooding
Infrastructure damage
Economic loss

More polluted runoff
Some of these climate-related changes have converged with more direct human impacts to influence water quality in the Great Lakes.
Cleanup measures adopted back in the 1970s imposed stringent limits on large point sources of nutrient pollution, like wastewater and factories. But smaller “nonpoint” sources, such as fertilizer and other nutrients washing off farm fields and suburban lawns, were addressed through weaker, voluntary controls. These have since become major pollution sources.
Since the mid-1990s, climate-driven increases in precipitation have carried growing quantities of nutrient runoff into Lake Erie. This rising load has triggered increasingly severe algal blooms, comparable in some ways to the events of the 1970s. Toledo’s 2014 crisis was not an anomaly.
These blooms can make lake water smell and taste bad, and sometimes make it dangerous to drink. They also have long-term impacts on the lakes’ ecosystems. They deplete oxygen, killing fish and spurring chemical processes that prime the waters of Lake Erie for larger future blooms. Low-oxygen water is more corrosive and can damage water pipes, causing poor taste or foul odors, and helps release trace metals that may also cause health problems.
So despite a half-century of advances, in many ways Great Lakes water quality is back to where it was in 1970, but with the added influence of a rapidly changing climate.
Filtering runoff
How can the region change course and build resilience into Great Lakes coastal communities? Thanks to a number of recent studies, including an intensive modeling analysis of future climate change in Indiana, which serves as a proxy for most of the region, we have a pretty good picture of what the future could look like.
As one might guess, warming will continue. Summertime water temperatures are projected to rise by about another 5 degrees Fahrenheit by midcentury, even if nations significantly reduce their greenhouse gas emissions. This will cause further declines in water quality and negatively impact coastal ecosystems.
The analysis also projects an increase in extreme precipitation and runoff, particularly in the winter and spring. These shifts will likely bring still more nutrient runoff, sediment contaminants and sewage overflows into coastal zones, even if surrounding states hold the actual quantities of these nutrients steady. More contaminants, coupled with higher temperatures, can trigger algal blooms that threaten water supplies.
But recent success stories point to strategies for tackling these problems, at least at the local and regional levels.
A number of large infrastructure projects are currently underway to improve stormwater management and municipal sewer systems, so that they can capture and process sewage and associated nutrients before they are transported to the Great Lakes. These initiatives will help control flooding and increase the supply of “gray water,” or used water from bathroom sinks, washing machines, tubs and showers, for uses such as landscaping.
Cities are coupling this “gray infrastructure” with green infrastructure projects, such as green roofs, infiltration gardensand reclaimed wetlands. These systems can filter water to help remove excess nutrients. They also will slow runoff during extreme precipitation events, thus recharging natural reservoirs.
Municipal water managers are also using smart technologies and improved remote sensing methods to create near-real-time warning systems for HABs that might help avert crises. Groups like the Cleveland Water Alliance, an association of industry, government and academic partners, are working to implement smart lake technologies in Lake Erie and other freshwater environments around the globe. Finally, states including Ohioand Indiana are moving to cut total nutrient inputs into the Great Lakes from all sources, and using advanced modeling to pinpoint those sources.
Together these developments could help reduce the size of HABs, and perhaps even reach the roughly 50% reduction in nutrient runoff that government studies suggest is needed to bring them back to their minimum extent in the mid-1990s.
Short of curbing global greenhouse gas emissions, keeping communities that rely so heavily on the Great Lakes livable will require all of these actions and more.
HWHF Funded Scientist, Michael Beck, and Colleague Discuss Economic Impact of Mangroves

Protecting Mangroves Can Protect Billions of Dollars in Global Flooding Damage Each Year
Authors: Michael Beck, Pelayo Menendez
March 10, 2020
Hurricanes and tropical storms are estimated to cost the U.S. economy more than US$50 billion yearly in damage from winds and flooding. And as these storms travel across the Atlantic, they also ravage many Caribbean nations.
We study coastal ecosystems and how to value the natural coastal defenses provided by mangroves, marshes and coral reefs. In a new study, we map flood risks along more than 435,000 miles (700,000 kilometers) of subtropical shoreline in 59 countries around the world.
Along these coasts, we calculate that flood risks exceed $730 billion annually in direct impacts to property. Many government agencies and insurers estimate that indirect impacts to livelihoods and other economic activity are two to three times these direct flood costs.
We also estimate that across these 59 countries, mangroves – salt-tolerant trees that grow along tropical coastlines worldwide – reduce risk to more than 15 million people and prevent more than $65 billion in property damages every year. Mangroves do this by blocking storm surge– the rise in sea level during storms – and dampening waves, which protect people and structures near the shore.
Battered coastlines
Tropical storms are a well-recognized hazard along many coasts. In 2019, which was an above-normal year for tropical storm activity, 90 named storms formed around the world, including 62 days with major tropical cyclones.
As one example, Hurricane Dorian devastated the northern Bahamas with sustained winds of some 185 miles per hour. Throughout its life, Dorian’s path impacted more than 17 nations and 15 U.S. states and territories, from Grenada to Newfoundland.
And Dorian was not even the strongest cyclone of the year. That title went to Super Typhoon Halong in the Western Pacific, which steered clear of land. Many scientists predict that climate change will make these storms more intense, with a likely increase in the proportion of storms that reach Categories 4 and 5.
It would be logical to assume that countries map the flood risks from these storms, since they have to protect residents who live near coasts, along with public infrastructure such as ports, airports, wastewater treatment centers and power plants. These facilities often are built in low-lying areas around urban and suburban centers.
However, governments and businesses only develop flood risk analyses for the shorelines of highly developed nations, where people have the resources to pay for or insure against these risks. This excludes most tropical countries, where many of the world’s most vulnerable people live.
Defending shorelines
Our study was designed to quantify these flood risks worldwide and identify solutions for reducing them. We used tools that are standard in the insurance and engineering industries, along with a five-step approach for calculating expected damage, to develop high-resolution estimates of flood risk globally. Then we coupled spatially explicit hydrodynamic flood models with economics to estimate impacts to people and property.
We focused on mangroves because they are large trees that grow quickly in salt water at the edge of the coastal zone, where they form a front line of defense. Mangroves are also excellent at trapping sediments and building land. On average, land around mangroves grows vertically by 1 to 10 millimeters per year.
We generated maps summarizing the benefits that mangroves provide in 20-kilometer coastal units around the world. They show that there are 100 coastal areas where mangroves avert $100 million or more in property damages every year. These are clearly priority zones where mangrove conservation and restoration will yield highly cost-effective benefits to people, property and national budgets.
According to our estimates, the U.S., China and Taiwan receive the greatest economic benefits – protection of property – from mangroves. Vietnam, India and Bangladesh receive the greatest social benefits – protection of people.
Mangroves as green infrastructure
Mangrove destruction has been widespread, largely because of coastal development and aquaculture. From 1980 through the early 2000s, the world lost up to 20% of existing mangrove habitat. The rate of loss has slowed but still continues, driven by urban expansion, pollution and agriculture.
Given our findings about how valuable mangroves are for coastal protection, we believe they should be viewed as national infrastructure and made eligible for funding from hazard mitigation and disaster recovery budgets, just like other coastal defense structures. Paying for mangrove restoration can work through the same approaches that are currently used to fund engineered protective structures such as seawalls.
Several new studies done collaboratively with Risk Management Solutions, a leading insurance risk modeling firm, show that coastal marshes and mangroves provide significant storm reduction benefits. These findings could underpin the development of innovative insurance options for natural systems.
Examples are already being developed for coral reefs in Mexicoand across the Caribbean. Conserving mangroves where they occur together with coral reefs can multiply the flood protection benefits from habitats.
Working with the World Bank, countries like the Philippines and Jamaica are assessing how the benefits of mangroves can be incorporated into national finances, disaster management and proposals for the U.N. Green Climate Fund, which was created in 2010 to help developing countries mitigate greenhouse gas emissions and adapt to climate change. Our work was supported by the World Bank and Germany’s International Climate Initiative to help inform solutions for nations that are most at risk.
In many places, preserving and restoring mangrove forests can be an extremely economically effective strategy for protecting coasts from tropical storm damage. As national governments and insurers grapple with disaster management costs that are growing nearly exponentially worldwide, we believe our research can create new opportunities to pay for mangrove conservation and restoration using climate adaptation, disaster risk reduction and insurance funds.
Blue-green algae linked to ALS in UM study, but researchers also found promising treatment
Originally published by the Miami Herald. Original article available here.
BY HOWARD COHEN FEBRUARY 28, 2020 11:45 AM
Florida’s persistent blue-green algae problem in waterways has already been linked to respiratory problems.
Now, a team of researchers, led by a University of Miami neurology professor, have found that the toxin in those algae blooms can lead to amyotrophic lateral sclerosis (ALS), a debilitating and progressive neurodegnerative disease that destroys nerve cells in the brain and spinal cord.
On the positive side, the new study also found a promising advancement in the treatment of ALS, commonly known as Lou Gehrig’s Disease.
The study, published in the Journal of Neuropathology & Experimental Neurology on Feb. 20, linked a toxin produced by blue-green algae to ALS. But it also found that a naturally occurring amino acid, L-serine, could be a possible treatment to combat the painful and deadly disease that wastes away muscles.
The scientists led by the study’s first author, David Davis, UM’s neurology professor and director of the Brain Endowment Bank, included Deborah Mash, a research professor at Nova Southeastern University’s Dr. Kiran C. Patel College of Allopathic Medicine, and Paul Alan Cox, executive director of the Brain Chemistry Labs in Jackson Hole, Wyoming.
The team, working at the Behavioral Science Foundation, a research facility on the island of St. Kitts, exposed vervet monkeys to a cyanobacterial neurotoxin called BMAA that is produced by blue-green algae, which has wreaked havoc on Florida’s shores.
The monkeys began to exhibit pathological changes in their bodies similar to what happens to people’s spinal cords in the early stages of ALS. Monkeys, rather than rodents, were used because they more closely mirror how ALS develops in humans, according to Davis.
But when these vervet monkeys were fed the L-serine amino acid at the same time they were dosed with the blue-green algae toxin for 140 days, the strategy proved illuminating. These monkeys showed a reduction in ALS-like maladies in their spinal cords.
“The big message is that dietary exposure to this cyanobacterial toxin triggers ALS-type pathology, and if you include L-serine in the diet, it could slow the progression of these pathological changes,” Davis said in a statement provided by UM. “I was surprised at how close the model mirrored ALS in humans.”
Mash said the results “holds promise for identifying a cause of sporadic ALS, which accounts for 90% of all ALS cases,” in a statement provided by Brain Chemistry Labs.
“While these data provide valuable insights, we do not yet know if L-serine will improve outcomes for human patients with ALS,” added ALS expert Walter Bradley, who was also an author on the study.
“We need to carefully continue FDA-approved clinical trials before we can recommend that L-serine be added to the neurologists’ toolbox for the treatment of ALS. However, this vervet BMAA model will be an important new tool in the quest for new drugs to treat ALS,” Bradley said in a Brain Chemistry Labs release.
This will be the “next step” in the researchers’ plans, Davis said in a UM report. “We are very curious about how BMAA affects individuals in South Florida.”
L-serine is found in soy products, sweet potatoes, eggs, meat, and some edible seaweed, according to Cognitive Vitality. L-serine is also sold as a dietary supplement.
The new study did not specifically say consuming these foods or taking a supplement would halt the progression of ALS or make one immune from getting the disease.
BLUE-GREEN ALGAE TOXINS
Howard Simon, founder of the Clean Okeechobee Waters Foundation, worked alongside Davis’ team. Simon, who retired as the executive director of the American Civil Liberties Union of Florida in 2018, summarized the blue-green toxic findings as such:
▪ Cyanobacteria produces an enormous number of toxins, including microcystin and BMAA (β-Methylamino- l-alanine).
▪ Microcystin has been linked to non-alcoholic liver disease and liver cancer.
▪ BMAA has been linked to neuro-degenerative diseases, including ALS, Alzheimer’s and Parkinson’s.
▪ The newest research establishes that BMAA is a cause of early stages of ALS in vervet monkeys.
“Of course, more research is needed to determine how much exposure to the cyanobacteria toxin BMAA, and over how long a period, increases the risk of neurodegenerative diseases — much like the question several decades ago: how many cigarettes will increase my risk of lung cancer?” Simon said in an email to the Miami Herald.
WHAT IS ALS?
ALS takes two forms: sporadic — the most common form accounting for between 90% to 95% of all cases — and familial, or inherited ALS, which accounts for 5% of the cases, according to the ALS Association.
Four drugs are approved by the FDA to treat ALS and there are nationwide support groups devoted to education on the disease, but there is no cure.
ALS usually strikes people between the ages of 40 and 70 and there are an estimated 16,000 Americans who have the disease at any given time, according to the ALS Association.
New York Yankees great Lou Gehrig, who died at age 37 of ALS in 1941, may be the adopted namesake of the disease that was discovered by French neurologist Jean-Martin Charcot in 1869, but other notable people also suffered from the ailment.
These names include theoretical physicist Stephen Hawking, Baseball Hall of Fame pitcher Jim “Catfish” Hunter, Toto bassist Mike Porcaro and actor David Niven.
FLORIDA’S ‘MASSIVE’ BLUE-GREEN ALGAE PROBLEM
“This latest research advances the understanding of crippling and terminal neuro-degenerative diseases, including ALS and Alzheimer’s disease,” said Simon. “The evidence from research is mounting, and it is pointing in the same direction: cyanobacteria (commonly called blue-green algae) produces the toxin BMAA, which has been linked to Alzheimer’s — and this latest research now shows that it triggers the earliest stages of ALS in vervet monkeys.”
Simon, now a public policy advocate in Sanibel, Simon hopes the research spurs action in Gov. Ron DeSantis’ administration.
In April 2019, DeSantis named the state’s first panel to tackle what he called a “massive problem” — blue-green algae.
Among those on the panel were researchers from Florida International University, the University of Florida, Florida Atlantic University, Florida Gulf Coast University and the Smithsonian Marine Station at Fort Pierce.
Simon says the UM-led researchers’ L-serine findings are timely today.
“This research lends greater urgency to the effort to get the Legislature to convert science into effective policies,” Simon said. “Pending legislation (Senate Bill 712, the Clean Waterways Act) needs to be strengthened with regulatory strategies to curb the pollution of Florida waters that fuels algae blooms — which in turn creates the toxin that is poisoning the people of Florida.”
