The air in Beijing, China is dirty, and a new report suggests it won’t be getting cleaner any time soon. Beijing residents received the grim news from the Beijing Municipal Research Institute of Environmental Protection regarding the city’s air pollution levels. Following studies done by the institute, researcher Pan Tao has estimated the return of safe air pollution levels in 2030. The World Health Organization has stated in the past that the concentration of PM2.5, particulate matter with a diameter of 2.5 micrometers or less per cubic meter, should not exceed 35 micrograms per cubic meter. In 2013, however, the level of PM2.5 in Beijing measured 89.5 micrograms per meter.
University of California, Berkeley has released a new set of interactive maps illustrating national energy usage. The visually striking if troubling images reveal a stark urban/suburban divide regarding carbon footprint, with the latter contributing far more in emissions than their city-dwelling counterparts.
Gazing at Chicago from the east, it’s impossible to ignore the city’s towering skyline. But the latest gem on the southwest shores of Lake Michigan won’t be made from glass and steel—it’s prairie grass and wetlands.
Northerly Island, a 91-acre peninsula that juts into Lake Michigan just south of the Loop, was promised a visionary makeover from Studio Gang and landscape architects JJR in 2010. Now the Chicago Park District and the U.S. Army Corps of Engineers are preparing to break ground this fall.
In May 2011, a shocking 80 percent of the 59 water samples taken from various sites in the Hudson River were determined to be unacceptable by the Riverkeeper, a non-profit organization dedicated to improving water quality on the Hudson River. What makes water “unacceptable”? Sampled sites are tested for enterococcus, a human pathogen often found in sewage that can potentially cause health problems like Meningitis and urinary tract infection.
According to the Environmental Protection Agency (EPA), Enterococcus count standards vary for different sites (for beaches, state governments discourage swimming if the count is over 35 colony forming units per 100ml). As for the part of Hudson River bordering New York City, an enterococcus count greater than 104 units per 100mL is considered “unacceptable.” And, quite frankly, gross.
