Scientist Alice Hamilton’s investigations into toxins in Chicago’s factories led to some of the first workplace safety laws in the country. She was known for her “shoe leather” epidemiology, wearing out the soles of her shoes from all the trips she made to Chicago homes, factories and even saloons to figure out what was making people sick ..read more

How should we decide what happens to our bodies when we die? And what implications does that decision have for the living? It’s common to think a burial at a cemetery is the final resting place for a loved one. But as we heard in our last episode, sometimes the need to progress as a society is in direct conflict with the desire to honor the dead. Today, we talk to one of the leaders of the Green Burial Council, funeral director Samuel Perry. His organization advocates and sets standards for “natural” burials, which he calls “the full body burial of the person directly in the ground with only b ..read more

Chicago — like so many other frigid American cities — can’t seem to kick its dependence on road salt. Last episode, we talked about why chloride from salt is harmful to both our natural and built environments. So we spent some time looking around for a cold-weather community that avoids using it altogether. And we found one! A little community way up north: Have you ever taken a ferry — or a plane — to Mackinac Island? Today, we hear from Dominick Miller, chief of marketing at the Mackinac State Historic Parks, about how the island deals with snow and ice in the winter without laying down a si ..read more

When Illinois legalized recreational use of marijuana five years ago, it came with a goal to right the wrongs of the war on drugs. “We’re addressing the past harms of discriminatory prosecution of drug laws,” Governor J.B. Pritzker said at the time. Many low level cannabis charges would automatically be expunged and legal aid would be made available. Last episode, we looked at two areas where the state spent the largest share of its $500 million in marijuana sales tax revenue: the state budget and R3 funding, a program to invest in communities that have been harmed by violence, excessive incar ..read more

What does it take to get a wrongful conviction overturned? Quite a lot, according to investigative reporter Alison Flowers, who says proving innocence is much more difficult than proving guilt. She has investigated the cases of many wrongfully convicted individuals, including that of Chicagoan Robert Johnson. In our last episode, Invisible Institute reporter Erisa Apantaku explained how Johnson has spent nearly 30 years in prison for a murder almost everyone knows he did not commit. What’s clear is that a lot must go right to overturn a wrongful conviction (and even more so before the exonerat ..read more
