  • How Bourbon and Big Data Are Cleaning Up Louisville

    The city of Louisville, built and sustained largely by pollution-inducing industries such as rubber factories and bourbon distilleries, is grappling with how to make the city air cleaner. The novel Air Louisville study integrated a partnership between a technology healthcare startup and a government-sponsored initiative that tracked incidence of asthma in different areas of the city. The results are already leading to healthier residents, but it is also just the starting point for long-term change.

  • Smoke and Mirrors: Inside Malawi's untold health crisis

    'Unclean' cooking - rudimentary, open-fire cooking practiced by millions of people around the world - is one of the leading causes of respiratory disease and death, especially for women, in developing countries; it is also a serious contributor to deforestation, air pollution, and continued poverty (due to the cost of fuel). But a solution has been gaining momentum in Malawi with help from the UN, in the form of clean, more efficient cookstoves that not only emit less smoke, but use less fuel and reduce the risk of burns to family members.

  • Can these 'stovers' finally crack the clean cooking problem?

    It's been proven within the cookstove industry that providing free cleaner-energy stoves to those cooking with traditional stoves or over open flame does not work as planned. Inyenyeri, a Rwandan cookstove company however, is adding a twist to that method by giving away their cookstoves that reduce emissions by 98 to 99 percent compared to wood or charcoal stoves for free, as long as the consumer agrees to buying their wood fuel pellets.

  • China's Crazy Plan to Keep Sand From Swallowing the World

    Overfarming, over-grazing, climate change and population growth are all to blame for turning Duolun County in China's Inner Mongolia region into a bigger desert than it was to begin with. With 87 percent of the area turned into desert, sandstorms began to be the norm and would often engulf the neighboring region of Beijing. The Duolun project attempts to stop this by embarking on a tree-planting mission. Not without it's limitations and criticisms, this solution is by no means perfect, but it's somewhat of a start that has seen Duolun reportedly increase to 31 percent forested land.

  • How Louisville Crowdsourced a Treatment For Asthma Attacks

    The Kentucky metro area has some of the worst air quality in the country, leading to concerning rates of asthma and respiratory disease well above the national averages. But a group called AIR Louisville has implemented a creative, crowdsourced solution that utilizes GPS-enabled inhalers to help patients identify and address asthma patterns based on numerous factors such as avoiding heavily-polluted parts of town, and identifying the best treatments based on lifestyle needs.

  • The Great Los Angeles Revolt Against Cars

    Los Angeles has faced deepening issues of severe traffic and extreme smog pollution in the past several decades, but for years intentions and promises to broadly improve transportation have fallen flat. At long last, the most congested city in the world - once home to the most extensive urban rail network on the planet - is reviving rail lines and trains as a solution to both issues. Robust public transport has proven to have multi-layered economic, cultural, environmental, and social benefits to communities.

  • The 'moss wall' that helps cities breathe

    Air pollution is a major health risk, and growing in severity as more of the population moves to urban (more polluted) areas. Several university friends from Germany developed a "CityTree," which filters toxic pollutants from the air with moss that can be installed around cities.
