The best trees to reduce air pollution

As Beijing grapples with pollution caused in large part by the increase in cars on the roads, a tech-based solution has appeared in the form of forward-thinking bicycles. The Chinese bike-sharing system, spearheaded by several startups, allows commuters to find a bike using GPS, pay for it using an app, and drop it off upon arriving to their destination, wherever that may be. A mix of private investment and government support has allowed this market to thrive.

Copenhagen is a highly livable city, thanks to policies that focus on making streets safe and convenient to walk. The bigger the city, the worse it is to design urban spaces only with cars in mind, says planner and architect Jan Gehl. His top advice is to gather data about people and their movements, making pedestrians as visible in city planning as automobile traffic.

The consumption of meat and dairy has long been deemed a leading cause of climate change, yet production continues to rise. To contribute to environmental sustainability, Dale Vince – owner of the U.K.’s Forest Green Rovers soccer team – has achieved the status of having the world's first carbon neutral team. From vegan-only menus to a solar-powered grass-cutter, the organization is bringing light to this topic in front of a new audience.

Bozeman, Montana, a city grappling with how to plan for growth in a smart and strategic way, is looking to learn from Fort Collins, Colorado. The two cities are similar in terms of the features that make them appealing: once low-cost, small college towns with beautiful scenery and lots of space. Now, Fort Collins’ population has soared, and critics say development could have been smarter. Bozeman is learning lessons about planning and inclusivity, hoping not to make the same mistakes.

In countries like Cambodia, Angola, and Mozambique, rats are saving lives by detecting untriggered land mines. An international nonprofit, Apopo, provides funding a training and works with local organizations to operate at the local level. The rats are light enough that they don’t trigger the explosives and can cover up to 2,000 square feet in just 20 minutes – something that would take a human up to four days to complete.

The focus on sound comes at a time when open kitchens and industrial hard-surface designs entice diners’ eyes, but might strain their ears.

Portland-based NGO, Micah Challenge USA, uses scripture to reach Evangelicals about climate change. The organization partners with legislation-making initiatives, travels to Christian colleges, and contacts national and local leaders urging them to join the Climate Solutions Caucus. Underpinning every initiative is a core strategy: climate change is causing people to suffer, especially those that are experiencing poverty, and as Christians, they are called to help the poor and end their suffering.

Pennsylvania law is preventing a Philadelphia neighborhood from converting an empty lot into a solar farm, but community members are working to fight against this by citing neighboring states that are seeing positive impact from similar projects. One such project is in Massachusetts where shared solar energy systems is helping to offset "80 percent of the power needs of a nearby assisted living facility, an affordable housing development, a family-owned hardware store and a non-profit serving those with disabilities."

The Asian Pacific AIDS Intervention Team (APAIT) works to positively impact the quality of life for medically underserved communities — particularly people of color within the LGBTQ+ community. APAIT’s primary focus is helping those with behavioral health challenges, housing insecurity, and who are at risk for HIV/AIDS, but has recently expanded its services to include helping those who are victims of sex trafficking.

To enhance rural access to healthcare in Nigeria, the Parkers Mobile Clinic partners with local volunteers, healthcare professionals, educators, and community development advocates to identify and remedy unique healthcare gaps. Outreach programs are then designed to provide localized mental health support, nutritional counseling, and other reproductive health services.
