Unintended Consequences of Human Actions on Ecosystems
Exploring the impacts of human activities on ecosystems, including creating niches for parasites and complex systems with unintended harms. Mention of merchandise with a message and reflections on sustainable housing on Lopez Island.
In this 233rd in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we talk about the state of the world through an evolutionary lens.
In this week’s episode, we discuss The Hope Accord, which calls for the “immediate suspension of Covid-19 mRNA vaccine products.” We encourage you to sign it. Then: wisdom from Charlie Munger on why we should prefer a world in which some people are not compensated for their losses (even if they didn’t deserve to lose), over having gameable systems in which cheaters flourish. Then: how the NYT stacks the deck in favor of sunscreen, by asking oncologists and dermatologists. When all you have is a hammer, everything looks like a nail. Finally, how chytrid fungus has wiped out frog populations and species across the world; how fever is used by endotherms like us to clear infections; and new research that finds that frogs like frog saunas, which not only feels great, but helps them clear fungal infections. The through-line: human hubris intervening in complex systems often ends badly.
