Designing for bikes has become a hallmark of forward-looking modern cities worldwide. Bike-friendly city ratings abound, and advocates promote cycling as a way to reduce problems ranging from air pollution to traffic deaths.
But urban cycling investments tend to focus on the needs of wealthy riders and neglect lower-income residents and people of color. This happens even though the majority of Americans who bike to work live in households that earn less than $10,000 yearly, and studies in lower-income neighborhoods in Brooklyn and Boston have found that the majority of bicyclists were non-white.
Air pollution levels in Bangkok have gotten so bad that the city's governor, Police General Asawin Kwanmuang, ordered more than 400 schools to close through Friday.
The return of supersonic airplanes would result in 96 million metric tons of carbon pollution per year, according to a new study released Wednesday by the International Council on Clean Transportation.
"In our era of runaway climate change, swapping fuel efficiency for speed is a devil's bargain," said Clare Lakewood, a senior attorney at the Center for Biological Diversity. "The aviation industry should be reducing its massive carbon footprint, not enlarging it with exorbitant luxuries for the super-wealthy. Supersonics are catastrophic for the climate."

Many cities, in recent years, have initiated tree planting campaigns to offset carbon dioxide emissions and improve urban microclimates.
In 2007, New York City launched MillionTrees NYC, a program designed to plant 1 million new trees along streets, in parks and on private and public properties by 2017. They hit their goal two years ahead of time.
Greta Thunberg to Davos Elite: Act Now on Climate to 'Safeguard the Future Living Conditions for Humankind'
By Andrea Germanos
Sixteen-year-old climate activist Greta Thunberg threw down the gauntlet to the global elite gathered in the Swiss Alps for the World Economic Forum (WEF) this week, urging them to work towards meaningful climate action in order to "safeguard the future living conditions for humankind."
"Some people say that the climate crisis is something that we all have created. But that is just another convenient lie," the Swedish teen says in a video posted to Twitter. The video was also posted on the WEF Facebook page and was intended to be shown to the attendees inside.
"Injustice anywhere is a threat to justice everywhere." Dr. Martin Luther King Jr.'s words and actions continue to resonate on the 90th anniversary of his birth.
As the country honors the life and legacy of the iconic civil rights leader today, we are reminded that the social justice and the climate movements are deeply connected.
