Not where I am but even if, what is the point of getting hysterical about it? You can change nothing and in all likelihood neither can 'the powers that be' make much difference. Cities and towns produce pollution, even aboriginal tribes in Australia have lung damage due to lying close to open fires to keep insects away, pristine air conditions are a myth as is pure drinking water, processed food contains harmful chemicals, micro plastics have even been found in Antarctica, never mind in the air and food in cities. Most early Homines didn't live past 25 and yet we live to be 80 or more despite our modern pollution, everything is a trade off. PM 2.5 particles are a temporary problem, it's not all year round and will come and go.
