NIMBYism around Heathrow
As a LHR 3rd runway supporter I have found that there are none so deaf etc etc.
The argument about the 3rd runway concentrates on pollution levels around LHR but people refuse to believe that having an 8 lane motorway adjacent to LHR carrying in excess of 211000 vehicles per day (Govt. stats 2017) creates more of a problem than the (currently) fewer than 1400 daily aircraft movements.
In the UK, vehicle emissions are checked once a year, perhaps twice if the mandatory check and routine service are carried out at different times..
I believe more diesel powered trucks and vans pass the area in 15 minutes than total aircraft movement for a day. - There is the problem.
