The world is grappling with a multitude of challenges, some of which are natural, while others are consequences of human actions. Despite numerous attempts to solve these issues, many remain unresolved due to the inefficacy of proposed solutions. As a result, experts from renowned institutions and organizations worldwide have turned to unconventional methods, ranging from radical to outright peculiar.
10. Embracing a Plant-Based or Vegan Diet
Albert Einstein once remarked, “Nothing will enhance human health and improve the prospects for life’s survival on Earth more than transitioning to a vegetarian diet.” Research supports Einstein’s claim, showing that adopting a vegetarian or vegan lifestyle is not only beneficial for personal health but also crucial in addressing one of humanity’s most urgent challenges—climate change. While the notion of eliminating meat consumption as a climate solution may initially appear far-fetched, scientific evidence underscores its validity.
A 2014 report in the Proceedings of the National Academy of Sciences highlighted that “livestock production is one of the most damaging contributors to climate change, degrading air quality, contaminating water sources, and consuming vast amounts of land.” According to the UN, livestock accounts for approximately 18 percent of climate change, though the World Watch estimates a much higher figure—51 percent. Additionally, livestock generates more greenhouse gases than all forms of transportation worldwide combined.
While eliminating meat consumption could significantly mitigate climate change, scientists recognize that a global shift to veganism or vegetarianism is highly impractical. Instead, they advocate for reducing meat intake if complete abstinence isn’t feasible. Initiatives like Meatless Mondays are a step in the right direction.
9. Perspiration-Powered Billboards
The Zika virus was first identified in 1947. Over the years, sporadic outbreaks have occurred in regions such as the Pacific Islands, Africa, and Southeast Asia. In early 2016, the virus reemerged with significant impact, particularly in Brazil.
While South America recorded the highest number of Zika cases, the virus also spread to other countries. Although not fatal and often presenting mild symptoms, Zika poses significant risks, particularly to pregnant women. Those infected may give birth to infants with microcephaly—abnormally small heads—or other neurological abnormalities.
To tackle the Aedes aegypti mosquitoes responsible for spreading Zika, Brazilian marketing agencies NBS and Posterscope devised an unconventional solution: sweating billboards. These billboards emit a mixture of lactic acid and carbon dioxide, mimicking human sweat and breath to lure and eliminate mosquitoes.
These innovative billboards can attract mosquitoes from up to 3 kilometers (2 miles) away. The creators have made the design publicly available, enabling other countries and organizations to replicate the technology.
8. A Massive Space-Based Sunshade
Launching a massive umbrella into space may sound like an extreme concept, but prominent organizations such as the European Union, Royal Society, NASA, and the Intergovernmental Panel on Climate Change consider it a feasible strategy to combat global warming.
Restoring Earth’s preindustrial climate could be achieved by blocking just 2–4 percent of the Sun’s rays. While a colossal space-based sunshade could theoretically accomplish this, the practical challenges of constructing and deploying such a structure into space make it nearly unattainable.
The initial concept for a giant space umbrella was proposed by James Early in 1989. His design featured a massive 2,000-kilometer-wide glass shield. However, the sheer weight of the structure posed a significant hurdle, necessitating its construction on the Moon.
Despite the impracticality of building a giant space umbrella, scientists continue to refine the idea. Some have proposed alternatives, such as a “ring of miniature umbrellas encircling the planet” or “55,000 wire mesh mirrors.”
7. Mealworms That Consume Plastic
Annually, the United States generates 33 million tons of plastic, with a mere 10 percent being recycled. This nonbiodegradable material has become a major contributor to global pollution due to its widespread production. Fortunately, scientists may have discovered a solution to this critical issue, and it doesn’t involve advanced technology or new materials. Instead, the answer lies in the microorganisms found in the digestive systems of “small, brownish, wriggly mealworms.”
Researchers Jun Yang and Yu Yang from Beihang University, along with Wei-Min Wu of Stanford University, found that mealworms can break down styrofoam and other plastics. Their study revealed that 100 mealworms can consume 34–39 milligrams of styrofoam daily. Remarkably, mealworms fed exclusively on styrofoam remained as healthy as those eating a standard bran diet.
This groundbreaking research, published in Environmental Science and Technology, also demonstrated that mealworms convert ingested plastic into biodegradable waste, suitable for use as plant fertilizer. While cockroaches can also consume plastic, they do not exhibit the same biodegradation capabilities as mealworms.
6. Artificial Plastic Trees
Although carbon dioxide constitutes a small portion of Earth’s atmosphere, it significantly influences the planet’s temperature. This colorless, odorless gas, exhaled by humans, contributes to numerous environmental issues, including ocean acidification, glacier melt, rising sea levels, and altered climate and weather patterns. Unlike nitrogen or oxygen, carbon dioxide traps the Sun’s heat, leading to the phenomenon known as global warming.
To combat rising carbon dioxide levels in the atmosphere, scientists are exploring unconventional yet scientifically viable solutions. Klaus Lackner from Columbia University proposed the use of synthetic plastic trees to absorb excess carbon dioxide.
These artificial trees are reportedly 1,000 times more effective than natural trees at capturing carbon dioxide. Each tree can absorb up to one ton of this greenhouse gas daily. Lackner estimates that 100 million such trees would be required to offset humanity’s total carbon emissions. However, the high cost of $20,000 per tree remains a significant barrier.
5. Consuming Insects
Contrary to common misconceptions, eating insects is neither harmful nor a passing trend. For millennia, our ancestors consumed bugs, and ancient civilizations like Rome and Greece incorporated them into their diets. In many cultures, insects such as caterpillars, grasshoppers, and worms are regarded as delicacies or aphrodisiacs.
Experts now propose that edible insects could play a crucial role in addressing global hunger. In 2013, the United Nations’ Food and Agriculture Organization published a comprehensive 200-page report highlighting how insect consumption could alleviate food shortages, insecurity, and hunger.
Insect farming is far more environmentally friendly compared to traditional livestock rearing. It generates fewer greenhouse gases, consumes less water, and utilizes waste materials as feed. Additionally, insect farming could create employment opportunities in rural communities.
Despite being a safe and protein-rich food source, many people are hesitant to include insects in their diets. However, experts remain optimistic, citing that “dietary habits can shift rapidly, especially in today’s interconnected world.”
4. Human Genetic Modification
Solutions to global warming generally fall into two categories: altering human behavior or modifying Earth’s natural systems. However, these approaches often prove either ineffective or risky. For instance, government policies rarely make a substantial impact on reducing carbon emissions, while geoengineering techniques, such as atmospheric sulfur injection, could lead to disastrous outcomes.
The shortcomings of current climate change strategies prompted three Oxford University researchers to propose a bold alternative. They argue that human engineering could be the most effective way to tackle global warming. In their study, published in Ethics, Policy and the Environment, they detailed methods to “modify ourselves” for this purpose.
Their first suggestion was inducing intolerance to red meat, given livestock’s significant role in climate change. Second, they proposed reducing human size to lower energy consumption. Third, they recommended enhancing human intelligence, as studies link higher cognitive ability to lower birthrates. Lastly, they suggested using hormones like oxytocin to foster greater empathy toward animals and others affected by global warming.
3. Shifting Earth’s Orbit Away from the Sun
Among the many extreme solutions proposed to combat global warming, one stands out as particularly radical: relocating Earth farther from the Sun. Scientists from NASA have suggested using comets or asteroids to shift our planet’s orbit, positioning it in a cooler and safer region of the solar system.
This plan, championed by NASA’s Greg Laughlin, Don Korycansky, and Fred Adams, involves techniques similar to those used to deflect comets or asteroids on a collision course with Earth. Essentially, an asteroid or comet would be guided to pass near Earth, transferring gravitational energy to our planet. If successful, this would accelerate Earth’s orbit, moving it away from the Sun.
In an ideal scenario, this plan would resolve global warming. However, in reality, executing such a scheme is nearly impossible and fraught with risks. A miscalculation in directing the asteroid or comet could cause it to collide with Earth, leading to catastrophic outcomes reminiscent of Hollywood disaster films.
Additionally, the Moon’s role complicates matters. The Moon influences many of Earth’s natural processes, and altering its distance from our planet could drastically disrupt our climate.
2. Implementing Blue Streetlights
While blue may seem an unusual choice for lighting, experts argue that it could address two widespread global issues: crime and suicide. In 2000, Glasgow, Scotland, introduced blue streetlights to enhance its cityscape.
Following the installation, an unexpected outcome emerged: crime rates in areas with blue lighting significantly declined. Encouraged by these results, Nara, Japan’s police department implemented blue streetlights across the region in 2005. Once again, crime rates fell, this time by 9 percent.
Beyond reducing crime, blue lights have also proven effective in deterring suicides. Railway companies like Japan’s Keihin Electric Express have installed blue lights at stations to prevent individuals from jumping in front of trains. The company reports that “no suicide attempts have occurred” since the lights were introduced.
Professor Tsuneo Suzuki of Keio University credits the crime-reducing and suicide-deterring effects of blue lights to their calming influence. However, he cautions that “it’s somewhat risky to assume that lighting color alone can prevent such issues.”
1. Large-Scale Female Sterilization
By 2030, India is projected to surpass China as the world’s most populous nation. In 1947, when India gained independence, its population stood at 345 million, but by 2014, it had soared to over one billion. This represents an increase of more than 900 million people in just 67 years.
To address its population surge, the Indian government initially promoted vasectomies for men. However, the initiative was abandoned due to societal resistance in a male-dominated, patriarchal culture. The government then shifted its focus to women, implementing tubectomies as an alternative.
India’s tubectomy campaign is notable for its scale and controversial incentives. Approximately 37 percent of married Indian women have undergone the procedure in sterilization camps nationwide. Between 2011 and 2012 alone, 4.6 million women were sterilized, raising ethical and humanitarian concerns.
In many nations, offering financial incentives for sterilization is prohibited, but in India, it’s a common practice. Both women and health workers receive monetary rewards—health workers are compensated for persuading women to undergo the procedure. Some women are reluctant but are pressured by their husbands due to the financial benefits. Beyond cash, these women and their families are often enticed with gifts like TVs, motorcycles, kitchen appliances, and even cars.
