The Biodiversity Crisis
Quantify the current biodiversity crisis: extinction rates 100-1000x the background rate; explain methods for measuring biodiversity loss (species-area relationship, population viability analysis, IUCN Red List categories); evaluate rewilding case studies — Yellowstone wolf reintroduction triggering a trophic cascade that changed river courses; Iberian lynx recovery; describe minimum viable population theory and conservation triage; examine ethical debates in deciding which species to prioritise
Typical age: 12–14 years
“Can your child describe what happened to Yellowstone National Park after wolves were reintroduced — what unexpected changes rippled through the whole ecosystem, including effects on rivers, as a result of one predator coming back?”
