(TMU) — A pair of young inventors from Mexico will unveil the very first organic leather made entirely from the nopal—or prickly-pear cactus this week—offering a sustainable, stylish, and eco-friendly alternative to leather.

The two innovators, Adrian Lopez and Marte Cazarez, will be travelling from the city of Guadalajara to the Lineapelle international leather trade exhibition in Milan, Italy, on October 2, where they will present the innovative leather substitute to the world’s top designers in hopes that the product can become a staple in the luxury fashion industry.

For two years, the two men worked on creating the leather alternative that they claim is not only environmentally sustainable and entirely plant-based but is also breathable and lasts for at least a decade, reports El Heraldo de México.

The invention comes as consumers and brands increasingly turn away from inferior faux leathers made with petroleum-based plastics, which are hard to clean and far less breathable than genuine animal leather.

The nopal cactus has long been a national symbol of Mexico as well as a crucial staple of the Mexican diet. Since pre-Hispanic times, the antioxidant-rich nopal has been prepared in countless ways within the Mexican kitchen—whether mixed with salads, meats, poultry, avocado, eggs, cheeses, or blended with corn tortillas, candies, and fruit juices. The staple crop is also used as feed for livestock. Millions of acres across the country are devoted to cultivating the plant, which produces abundant amounts of both fruit and vegetables.

In addition to its edible qualities, the prickly pear has also been used for medicinal purposes and as a dye for textiles and murals. In recent years, Mexican inventors have even created a nopal fiber that can be used in the aeronautics industry or as a substitute plastic for biodegradable straws and cutlery.

Cazarez explained:

“The cactus has many cosmetic applications: in shampoo, in creams.

So, we figured: ‘If it’s good for the skin, why not create a [nopal] leather?’, And this was how the idea was born.”

The two young men worked to develop the idea despite some discouraging the pair and calling the idea crazy.

Lopez said:

“Mexico has the potential to innovate, [especially] with nopal, which is the symbol of the country. But so many people told us we were crazy! Even our engineers told us that that could not be done. 

We said: ‘why not? We are in Mexico, we are Mexicans, what raw material is more suitable for us to exploit than nopal? It grows by itself, it doesn’t need much watering, it doesn’t waste much water.’

That’s when we began to experiment with the nopal and, after several tests, we were able to develop a resistant material.”

Lopez and Cazarez were also inspired by recent innovations coming out of Europe, including leathers such as Frumat—an Italian textile made from the waste from processing apples—and Piñatex, a Spanish textile woven from the fibers of discarded pineapple leaves.

After a long period of trial and error, the two made a breakthrough a few weeks ago when they devised an organic blend of nopal and cotton with the proper hand feel and attractive look that consumers require. Lopez and Cazarez also guarantee that their product can last for 10 years and has the chemical and physical properties required by the fashion, furniture, leather goods, and automotive industries.

The nopal leather can be used to make “a small dress, a purse, a belt, a watch strap, a small bookcase, or an armchair,” Cazarez noted. He added:

“Any leather can be replaced with organic alternatives; animal leathers or synthetic leathers can be replaced by organic alternatives. This is the cycle, and it supports our ecosystem.”

The inventors also rooted their dreams in the goal of assisting the farmers who grow and tend the massive cacti. Lopez said:

“It makes our work more meaningful because this isn’t only about fashion and the environment.

We also want to somehow support workers in the fields and create jobs, even indirectly.”

Scientists Horrified as Over 27,000 Leaking Barrels of Toxic DDT Discovered on Seafloor Near LA

Over 27,000 barrels of the toxic insecticide DDT have been found so far on the seafloor about 12 miles off the coast of Los Angeles, in what could be one of the greatest examples of industrial pollution uncovered in recent memory.

The barrels have been leaking, and researchers fear that there could be up to a few hundred thousand barrels of DDT waste in total. Over 100,000 total objects have been found in the area by researchers at the University of California San Diego’s Scripps Institution of Oceanography.

The barrels cover an area roughly spanning double the size of Manhattan and lie off the coast of Santa Catalina Island, which is home to dozens of endemic species that exist nowhere else in the world.

DDT waste has been linked to cancer and widespread disease among humans as well as mass die-off events in the natural world. It is likely that the vast trove of illegally dumped DDT could be linked to the widespread cancer faced by sea lions along the West Coast.

“Unfortunately, the basin offshore Los Angeles has been a dumping ground for industrial waste for several decades, beginning in the 1930s. We found an extensive debris field in the wide area survey,” said Eric Terrill, chief scientist of the expedition and director of the Marine Physical Laboratory at Scripps Institution of Oceanography, said in a statement.

Los Angeles Times reports that shipping logs from a disposal company implicate Montrose Chemical Corp. of California, a company that produced DDT, in likely dumping some 2,000 barrels of DDT-laced sludge each month from 1947 to 1961 into a designated dumpsite.

Additionally, logs from other entities show that several other industrial concerns in Southern California used the basin as a dumping ground until 1972, when the Marine Protection, Research and Sanctuaries Act was enacted.

Florida Set to Release a Billion Genetically Modified Mosquitoes in “Nightmare” Experiment

Environmentalists and Florida residents voiced concern and outrage Monday as state government officials and the biotechnology giant Oxitec announced plans to move ahead this week with a pilot project that involves releasing up to a billion genetically engineered mosquitoes in Monroe County over a two-year period.

Presented by local authorities as an effort to control the population of Aedes aegypti—a mosquito species that can carry both the dengue and yellow fever virus—critics warn that the effort’s supposed benefits and its potential negative consequences have not been sufficiently studied.

Responding to news that the first boxes of genetically modified mosquitos are set to be placed in six locations in Monroe County this week, Friends of the Earth noted in a press release that “scientists have raised concerns that GE mosquitoes could create hybrid wild mosquitoes which could worsen the spread of mosquito-borne diseases and could be more resistant to insecticides than the original wild mosquitoes.”

Dana Perls, food and technology program manager at Friends of the Earth, called on the Environmental Protection Agency (EPA)—which approved the project last May—to “halt this live experiment immediately.”

“This is a dark moment in history,” said Perls. “The release of genetically engineered mosquitoes puts Floridians, the environment, and endangered species at risk in the midst of a pandemic. This release is about maximizing Oxitec’s profits, not about the pressing need to address mosquito-borne diseases.”

The Florida Keys Mosquito Control District and Oxitec said late last week that “less than 12,000 mosquitoes are expected to emerge each week” in Monroe Country over a duration of around three months, the initial phase of the experiment.

The stated goal of the project is for Oxitec’s genetically altered, non-biting male mosquitos to mate with the local biting female population, producing female offspring that die in the larval stage before they can spread disease.

As the Miami Herald explained earlier this year: “A ‘death mechanism’ designed into mosquitoes is meant to ensure no viable female offspring will result from the mating, according to Oxitec. The male offspring will pass on the ‘self-limiting gene’ to half of their offspring, said company spokesman Ross Bethell.”

While Oxitec’s CEO claims “strong public support” from Florida Keys communities, the project has sparked protests and pushback from local residents since the proposal was first floated.

“My family’s bodies, blood, and private property are being used in this trial without human safety studies or my consent,” Mara Daly, a resident and local business owner in Key Largo, Florida, said in a statement Monday.

Barry Wray, executive director of the Florida Keys Environmental Coalition, added that the “EPA has set the lowest possible bar for approving genetically engineered insects and has opened Pandora’s Box for future experiments that will slide through with little investigation.”

“Everyone should be writing the White House to stop this release until there are regulations and standards that truly protect us,” Wray said.

Rapid Melting of Glaciers Has Shifted Earth’s Axis, Study Reveals

Since 1980, the planet’s north and south poles have moved roughly four meters in distance, and new research shows that shifts in the Earth’s rotational axis have accelerated since the 1990s as a result of the widespread melting of glaciers—a clear manifestation, scientists say, of the climate emergency.

“Faster ice melting under global warming was the most likely cause of the directional change of the polar drift in the 1990s,” Shanshan Deng—a researcher from the Institute of Geographic Sciences and Natural Resources Research at the Chinese Academy of Sciencestold the American Geophysical Union (AGU) Thursday.

In a study published last month in the peer-reviewed journal Geophysical Research Letter, Deng and her co-authors found that changes in terrestrial water storage—particularly the accelerated loss of water stored on land due to melting glaciers—redistributed enough of the world’s mass to drive “the rapid polar drift toward the east after the 1990s.”

As The Guardian explained Friday:

The planet’s geographic north and south poles are the point where its axis of rotation intersects the surface, but they are not fixed. Changes in how the Earth’s mass is distributed around the planet cause the axis, and therefore the poles, to move.

In the past, only natural factors such as ocean currents and the convection of hot rock in the deep Earth contributed to the drifting position of the poles. But the new research shows that since the 1990s, the loss of hundreds of billions of tons of ice a year into the oceans resulting from the climate crisis has caused the poles to move in new directions.

The scientists found the direction of polar drift shifted from southward to eastward in 1995 and that the average speed of drift from 1995 to 2020 was 17 times faster than from 1981 to 1995.

The AGU noted that “researchers have been able to determine the causes of polar drifts starting from 2002 based on data from the Gravity Recovery and Climate Experiment (GRACE), a joint mission by NASA and the German Aerospace Center, launched with twin satellites that year and a follow-up mission in 2018.”

Data from the GRACE satellites has enabled scientists to “link glacial melting to movements of the pole in 2005 and 2012, both following increases in ice losses,” The Guardian reported. “But Deng’s research breaks new ground by extending the link to before the satellite’s launch, showing human activities have been shifting the poles since the 1990s, almost three decades ago.”

While Deng’s team showed that the accelerated decline in water stored on land stemming from glacial losses “is the main driver” of polar drift since the 1990s, the researchers wrote that groundwater depletion in non-glacial regions has also contributed to the movements.

“Groundwater is stored under land but, once pumped up for drinking or agriculture, most eventually flows to sea, redistributing its weight around the world,” The Guardian noted. “In the past 50 years, humanity has removed 18 trillion tons of water from deep underground reservoirs without it being replaced.”

Vincent Humphrey, a climate scientist at the University of Zurich who was not involved in the study, told AGU that the new research “tells you how strong this mass change is—it’s so big that it can change the axis of the Earth.”

This shift in the Earth’s axis, however, is too small to affect daily life, Humphrey added. It could change the length of day, but only by milliseconds.

Nonetheless, other climate experts such as Jonathan Overpeck of the University of Arizona, have said before that the mere fact that the climate crisis is driving polar movements demonstrates “how real and profoundly large an impact humans are having on the planet.”
