This is a misleading title here, there are as much as 70% fewer pollinators in circumstances where specific pollutants are present:

"Scientists studying air pollutants from both urban and rural environments found that there are up to 70% fewer pollinators, up to 90% less flower visits, and an overall 31% in pollination reduction in test plants when there were several common ground-level air pollutants present – including diesel exhaust pollutants and ozone."

That's just not going to be the most common interpretation of "Scientists find there are 70% fewer pollinators, due to air pollution" as a title.

Anyhoo, air pollution is very bad and governments should be laser focused on selling the benefits of reducing fossil fuel burning for transportation as a personal health benefit more so than as a climate change mitigation strategy.
