London broke its annual air pollution limit last Thursday, just five days into 2017. UK law states that hourly levels of toxic nitrogen dioxide (NO2) must not exceed 200 micrograms per cubic metre (µg/m3) more than 18 times in a whole year, yet this limit was reached and broken on 5th January on Brixton Road in Lambeth. This doesn’t come as much of a surprise however, when you take a look at last year’s air pollution statistics for Brixton Road: in 2016 it broke the hourly limit 502 times.
It is expected that many other London hotspots will also frequently break the limit throughout the year. London’s Putney High Street broke the hourly limits 1,221 times last year, vastly exceeding the permitted 18 annual breaches, and many other busy areas such as Kings Road, Oxford Street and the Strand struggled with the limit, and will continue to do so this year.

Ohio State University has released the results of a study of food waste, which observed the actions of restaurant diners. The results show that education is a successful tool in beating the production of food waste, however if people are informed their waste will be composted, the education benefits disappear and people are happy to waste as much food as those who are completely uneducated in the environmental impact of their waste.
Lead researcher Danyi Qi, a graduate student in agricultural economics at The Ohio State University, said of the matter:
“This presents a tricky situation for policymakers figuring out how to manage food waste, because the top tactics are prevention (through education) and diversion (through composting). When you do both, they cancel each other out — they work at cross purposes.”
