We really ought to show more care and test more when we are creating chemical marvels and new materials. At a certain level of scale a lot of the inventions of the last 50 years turned out to be quite damaging to our health and environment. We don't seem to have the balance right yet comparing freedom to release whatever and complete lockdown until something is proved safe and we keep damaging people and the biodiversity of the planet on which we depend.
