At 6am on March 30th I will pedal away from Morden Underground station at the southern terminus of the Northern Line. Over the next six hours I will visit each of the 33 consecutive stations on the Northern Line by bicycle, finishing in High Barnet, N.London.
On the top tube of my bicycle will be a black carbon (diesel emission) monitor; by my throat will be a sampling tube and mounted on the pannier rack at the back will be a sign, “Did you know that cycling exposes you to less air pollution than buses, cars or trains?”
The WHO reported in November 2016 that air pollution currently causes 6.5 million early deaths a year. That is double the number of people lost to HIV/Aids, tuberculosis and malaria combined. In London nearly 9,500 people die early each year due to long-term exposure to air pollution – that’s twice as many as died during the Great Smog of 1952.
Air pollution data has been recorded by KCL for the entire London Underground lines. The black carbon monitor provided by KCL is expected to provide data during the ride, presenting the case that swapping your Underground journey for a bicycle will reduce your exposure to air pollution.
I am a journalist; not a researcher or policy maker. But I hope and continue to believe that seemingly small and insignificant acts by individuals can be a powerful tool to draw awareness to this elephant in our atmosphere. From starting points like these we can also draw collected consciousness to tackling climate change as well.
I would be delighted if any other keen cyclists would like to participate. Join me at 6am this Thursday at Morden Underground. Mike’s Bike Surgery (just a stone’s throw from Morden Underground) will be serving coffee from just before 6am. You will need a bicycle and an air pollution mask if you have one.
