Using technology to capture and destroy toxic chemicals in drinking water
Nature has an incredible capacity to heal itself and mitigate the effects of pollution. However, human activities that cause environmental damage and ecosystem disruption often require intervention to restore balance. The presence of toxic 'forever chemicals', such as PFASs (per- and polyfluoroalkyl substances), in drinking water is a pressing issue that necessitates the use of technology to capture and destroy these harmful substances.
PFASs are man-made chemicals that are incredibly resistant to breakdown, earning them the moniker of 'forever chemicals'. They are widely used due to their ability to repel oil and water and can be found in various products, including firefighting foams, cosmetics, non-stick cookware, clothing, furniture, adhesives, and food packaging. The indestructibility of PFASs has led to their accumulation in soil and water sources, posing a significant threat to human health and the environment.
Regulatory efforts and public concern have spurred a race to develop innovative solutions for purging PFASs from drinking water. One approach that has gained traction is the use of granular activated carbon (GAC). GAC is a porous material, or sorbent, that can effectively trap and contain PFASs. While GAC has shown promise, it does not capture all PFASs equally well, and the process of trucking carbon to reactivation kilns for the destruction of the collected chemicals contributes to climate change.
To address these challenges, scientists have developed and successfully tested novel technologies. NCCOS scientists, for instance, have built upon nanobubble ozone technology (NBOT) to destroy PFASs. NBOT involves impregnating ultrafine microbubbles with ozone and releasing them into the water. While ozone alone is insufficient to break the strong carbon-fluorine bonds in PFASs, combining NBOT with properly tuned ultraviolet (UV) light provides the necessary energy to shatter these bonds. This process results in the formation of fluorine gas and carbon dioxide gas, which evaporate from the water, leaving behind only oxygen and no harmful residues.
Another groundbreaking technology is supercritical water oxidation, developed by the scientific nonprofit Battelle. This process involves increasing both the temperature and pressure of the water to a critical point, facilitating the natural oxidation and breakdown of PFASs within seconds. These innovative solutions offer hope in the fight against toxic 'forever chemicals' in drinking water, protecting human health and the environment from their insidious effects.

Reducing plastic pollution in the ocean
Plastic pollution in the ocean is a critical and complex issue that requires collective efforts to address effectively. While cleanup initiatives are commendable, the key to reducing plastic pollution in the ocean lies in systemic change and individual actions that complement larger-scale initiatives. Here are some detailed and instructive ways to reduce plastic pollution in the ocean:
Reduce Single-Use Plastic Consumption:
The first step is to minimize your use of single-use plastics, such as plastic bags, water bottles, straws, cups, utensils, and takeout containers. Refuse any single-use plastics that you don't need and opt for reusable alternatives instead. Carry reusable grocery bags, produce bags, bottles, utensils, and coffee cups with you. Let businesses know that you prefer eco-friendly options, and support policies that limit, tax, or ban unnecessary single-use plastic items.
Participate in Beach Cleanups:
Get involved in local beach or waterway cleanups to remove plastics from the ocean and prevent them from entering in the first place. You can organize or join a cleanup event with friends, family, or local organizations. Global initiatives like the Global Ocean Cleanup or the International Coastal Cleanup are also excellent opportunities to contribute to the global movement against plastic waste.
Properly Dispose of Plastics:
Ensure that the plastics you use are properly disposed of and recycled. When plastics can't be recycled, dispose of them responsibly to prevent them from ending up in the ocean. Currently, only about 9% of plastic worldwide is recycled, so increasing recycling rates can significantly reduce ocean plastic pollution.
Stay Informed and Spread Awareness:
Stay informed about plastic pollution issues and help spread awareness among your friends and family. Host documentary screenings or engage with non-profit organizations working to reduce plastic pollution, such as the Oceanic Society, Plastic Pollution Coalition, or the Plastic Soup Foundation. Your donations, even if small, can make a significant difference in supporting their important work.
Support Systemic Change:
Advocate for systemic change by supporting policies and regulations that reduce plastic pollution. Hundreds of organizations and businesses have worked with United Nations member states to enact a global plastics treaty. Support similar initiatives in your community and promote sustainable practices that reduce the use of plastic and encourage recycling.
By combining individual actions with collective efforts, we can make significant strides in reducing plastic pollution in the ocean and protecting our marine ecosystems for future generations.

Conserving energy and using fuel-efficient transport
Public Transportation: Using public transportation is one of the most effective ways to conserve energy and reduce pollution. Opting for public transit options such as buses, trains, and subways can significantly decrease carbon dioxide emissions. For example, a person switching from a 20-mile solo commute by car to public transportation can reduce their annual CO2 emissions by more than 48,000 pounds. This is equivalent to a 10% reduction in greenhouse gases produced by a typical two-adult, two-car household. Additionally, public transportation helps reduce congestion, saving time and money for commuters.
Carpooling and Active Commuting: Carpooling, or sharing rides, is another way to reduce the number of vehicles on the road and decrease emissions. Whenever possible, consider walking or biking to your destination, as this not only reduces pollution but also provides health benefits.
Electric Vehicles (EVs): The shift towards electric vehicles is a significant step towards decarbonizing transport. Electric cars, trucks, and motorcycles are much more efficient than traditional gasoline-powered vehicles, which have extremely low fuel efficiency. Governments and organizations are encouraging the adoption of EVs through various policies and incentives, such as subsidies and the development of charging infrastructure.
Fuel Alternatives: In addition to electrification, there is a growing focus on alternative fuels such as hydrogen, sustainable aviation fuel (SAF), and green methanol. These cleaner fuels can significantly reduce greenhouse gas emissions and air pollution from NOx, SOx, and particulate matter.
Smart Transport and Infrastructure: Utilizing data analytics, artificial intelligence, and the Internet of Things (IoT) can optimize routing and reduce fuel consumption. This includes improvements in infrastructure, such as the use of roundabouts and efficient traffic light timing, which can enhance vehicle and infrastructure efficiency. Additionally, investing in high-speed rail networks can provide a more energy-efficient alternative to conventional rail systems.
Vehicle Maintenance and Efficient Practices: Properly maintaining vehicles and following efficient practices can also reduce pollution. This includes keeping engines tuned, ensuring proper tire inflation, and following gasoline refueling instructions to prevent spills. Reducing excessive idling and minimizing the number of trips can also help conserve fuel and reduce emissions.
By implementing these measures and adopting more fuel-efficient transport options, we can collectively work towards reducing pollution, conserving energy, and creating a more sustainable future.

Reducing exposure to pesticides
While human activities are responsible for environmental pollution, there are ways to reduce it. One way nature gets rid of toxic pollution is by using technology to capture and destroy harmful chemicals. For example, in Wilmington, North Carolina, a plant serving 200,000 people draws water from the Cape Fear River, which was found to have high levels of EPA-regulated PFASs. After the installation of a sorbent system, levels of these chemicals fell below the new EPA limits.
To reduce exposure to pesticides, it is important to minimize the amount of pesticide used, select lower-toxicity products, and use protective equipment. You can also adopt an Integrated Pest Management (IPM) approach, which emphasizes prevention, sanitation, and exclusion, and only utilizes pesticides as a last resort. When using pesticides, always read the label and follow the directions closely. Make sure to use the appropriate amount and wear the minimum amount of protective equipment, such as gloves or goggles, as listed on the label. Avoid allowing children, pets, or sensitive individuals in treatment areas during pesticide application, and consider staying out of treated areas for the recommended amount of time afterward.
Additionally, you can reduce your exposure to pesticides by being mindful of the food you consume. Wash and peel produce, and consider growing your own food or purchasing from local farmers' markets where you can inquire about their pesticide use. Selecting a variety of foods from a variety of sources can also help reduce your exposure.
To minimize pesticide exposure in your community, consider participating in initiatives such as the Environmental Protection Agency's (EPA) "Reduce Your Child's Chances of Pesticide Poisoning" campaign or implementing IPM in schools and public spaces.
By following these measures, individuals and communities can play a role in reducing exposure to pesticides and contributing to a healthier environment.
