Global population growth promises a drastic spike in public health emergencies

There are questions that worry me profoundly as an environmental health and population scientist.
Will we have enough food for a growing global population? How will we take care of more people in the next pandemic? What will heat do to millions with hypertension? Will countries wage water wars because of increasing droughts?
These risks all have three things in common: health, climate change and a growing population that the United Nations determined passed 8 billion people in November 2022, which is double the population of just 48 years ago.

The lack of regional and local vehicle traffic during the pandemic greatly reduced measurable pollution in Great Smoky Mountains National Park.
This is your Hellbender weekend read, and the first in an occasional Hellbender Press series about the effects of the Covid-19 pandemic on the natural world
Great Smoky Mountains National Park shut down for six weeks in 2020 during the Covid-19 pandemic. Recorded emissions reductions during that period in part illustrate the role motor vehicles play in the park's vexing air-quality issues. The full cascade of effects from the pollution reductions are still being studied.
Hellbender Press interviewed park air quality specialist Jim Renfro about the marked reduction of carbon dioxide and other pollutants documented during the park closure during the pandemic, and the special scientific opportunities it presents. He responded to the following questions via email.
