It also looks at extinction, invasive species, garden battles, and the outsized role these tiny creatures play in ecosystems, history, and even science.

A humble lawn weed gets a wild glow-up. The conversation explores seed-flight physics, edible uses, old medical lore, pollinator power, wartime rubber experiments, and how suburban lawn culture turned a useful plant into a backyard villain.

A deep dive into permaculture as a smarter way to design farms and backyards. They explore zones, sectors, forest gardens, rain-catching swales, and using animals, insects, and plant pairings to make landscapes work together. There is also a look at how it stacks up against industrial agriculture and where the science is still catching up.
