"Sometimes the best things you can do are invisible.
Such as fighting cholera by ensuring drinking water wasn’t contaminated by
sewage, as happened in London in the 1840s.
Or setting up an emissions trading scheme, which drove emissions down, despite
former prime minister Tony Abbott attacking it as a “so-called market in the
non-delivery of an invisible substance to no one”.
Air free from contamination is as invisible as uncontaminated water, but the
case for air isn’t yet as widely accepted as it is for water.
Air pollution from motor vehicles kills about 280 Australians per year, yet
Australian petrol is allowed to contain 15 times as much sulphur as petrol sold
in the US, the UK, Europe, Korea, Japan and New Zealand. Australia is planning
to adopt in 2024 the standard adopted elsewhere in 2015.
And poor air quality harms us in ways that fall short of death."
