🌎 Population Collapse: Our Next Apocalypse?

For decades, we heard warnings about a “population bomb.” Now, the conversation has shifted toward the opposite concern: population decline and what it could mean for society.

Join us for this fascinating two-part speaker series exploring how human population trends have changed—and what the future may hold.

📅 Part 1: Thursday, September 24
⏰ 6:30–7:30 PM
📅 Part 2: Thursday, October 1
⏰ 6:30 PM

📍 Effie Yeaw Nature Center
2850 San Lorenzo Way, Carmichael, CA

Led by Greg Dewey, this thought-provoking series will explore why the predicted “population bomb” never happened and the potential societal impacts of population decline. Each lecture will include time for audience discussion and questions.

Come curious, bring your questions, and join the conversation!

A very hungry caterpillar left those wombat-like droppings shown in an earlier post. Watching for these is a great assist when looking for Monarch larvae activity among the milkweeds. We continue to see Monarchs floating through almost daily.
