These are all genuine and critical problems, but the solution can really only come from governments and industry, with more emphasis on public transport, better city design and industry getting greener.

We can praise those who organise their lives in such ways as to not be too much of a burden on the planet but I don’t believe it’s effective to shame those that don’t, or do it in different ways than you expect.

It is effective to put pressure on governments and industry though.
