Pros and cons of lockdown from public health POV.
"The streets are now quieter and safer with more people choosing to walk and cycle and greater use of local shops and parks. People are more aware of pollution; their health and quality of life issues, and the lockdown seems to have encouraged a new spirit of localism."
"there has been an increase in people driving their cars at excessive speeds. This is dangerous for everyone and deters people from walking and cycling. People are also concerned about using public transport for fear of catching COVID-19.
Therefore, as travel restrictions are lifted, we're likely to see more people choosing to drive rather than use the train or bus than before the lockdown. This will greatly increase air pollution (motor vehicles are responsible for more than half of the air pollution in London) which could further impact those recovering from COVID-19."
