Taylor Swift enjoyed a girls' night out in Beverly Hills with friends Brittany Mahomes and Lindsay Bell, looking chic in a black mini dress and thigh-high boots. However, her use of a private jet has sparked backlash among her fans, who are concerned about the environmental impact. An Instagram page tracking her flights claims she has emitted 138 tons of CO2 in three months, leading to criticism despite her previous defense by fans. Swift's team has responded by stating that her jet is often loaned out to others, suggesting she is not solely responsible for the emissions.
Recent research has revealed that paper straws, once thought to be an eco-friendly alternative to plastic, may contain harmful 'forever chemicals' known as PFAS, which are not easily biodegradable and could pose health and environmental risks. The study conducted by the University of Antwerp found PFAS in various straw materials, with stainless steel being the exception. These findings suggest that even eco-friendly products can contribute to pollution if they contain PFAS. The researchers recommend using stainless steel straws or avoiding straws altogether to minimize potential harm.
The Stanley water bottle craze has taken America by storm, with viral TikTok videos showing people clamoring for the latest color drops at Target, sometimes paying over 200% of retail price on secondary markets. This trend reflects a broader history of bottled water and reusable water bottles in the U.S., where despite the rise of reusable bottles suggesting an eco-friendly shift, bottled water sales have also surged to record highs. Critics argue that the trend is less about environmentalism and more about fashion and identity, as consumers collect bottles as accessories that communicate health, lifestyle, and status. The trend's environmental benefits are questioned as many of these bottles may eventually contribute to landfill waste.
Researchers at Caltech have developed a new method for producing propylene oxide, a common chemical feedstock, using a combination of platinum oxide and palladium oxide catalysts. This method utilizes water as a reactant, avoiding the use of toxic chemicals and producing hydrogen gas as the only byproduct. The new catalyst mixture not only makes the production process safer and more environmentally friendly but also increases the production rate by 10 times and efficiency by 13 percent. The study, published in Science, marks a significant step towards cleaner chemical manufacturing and the team is now looking to adapt this laboratory success for industrial applications.
A woman on TikTok, known as Happy Earth Habits (@skysaba), has demonstrated through a side-by-side comparison that eco-friendly cleaners can be just as effective as conventional chemical cleaners. By using two sprays of each on juice stains, she showed that the eco-friendly option cleaned the counter thoroughly. This supports the idea that switching to natural, biodegradable cleaning products is not only better for health by reducing exposure to toxins but also benefits the environment by decreasing pollution. Commenters on social media have expressed support for the eco-friendly cleaning method, with some even sharing their own positive experiences with homemade cleaners.
UCLA scientist Catherine Carpenter, Ph.D., warns that grilling meat at high temperatures can increase cancer risk due to the formation of carcinogenic chemicals like HCAs and PAHs when fat burns and meat chars. Long-term exposure to these chemicals is associated with higher risks of prostate, colon, and pancreatic cancers. The practice of grilling is prevalent in the U.S., particularly among men and middle-aged individuals. To reduce health risks, Carpenter recommends cooking with indirect heat, frequent turning of meat, trimming charred parts, and using citrus-based marinades. Additionally, the beef industry contributes significantly to climate change, and reducing meat consumption can benefit both health and the environment.
