Cancer exploded because we bathed the entire population in petrochemical exhaust.

Diesel engines, jet fuel, gasoline, benzene — all Group 1 carcinogens — became ubiquitous in the 20th century. Every highway, every airport, every port, every city bus, every idling truck. Nobody escapes it. You breathe it at school, at work, in traffic, in your neighborhood.

The timeline matches perfectly. As fossil fuel combustion scaled up through the mid-20th century, cancer rates followed. Not because people suddenly started eating badly or living longer — but because the air itself became carcinogenic.

It's not a mystery. It's not complicated. The most well-documented carcinogens on earth were pumped into the air everyone breathes, every day, for 80 years.

And it gets almost no attention — while billions are spent telling people to wear sunscreen and eat more vegetables.
