EARS TO THE GROUND-

? There are no stupid questions. CrowdScience, a BBC podcast, asks (and answers) all the embarrassing, hilarious, and seemingly inconsequential science questions you may have. In each episode, host Anand Jagatia tackles one query submitted by a listener with the help of experts.

Are cars apex predators? asks listener Eoin Donnellan. Cars and apex predators like tigers, sharks, and wolves have a lot in common — nothing attacks or eats them, and they impact wildlife and the ecosystem directly and indirectly, most significantly by killing. Jagatia interviews zoologist Sam Helle, environmentalist Paul Donald, head of an environmental construction company Antonio Borges, and environmental chemist Zhenya Tian to discuss the damage that cars have on the ecosystem, and how that compares to the effect of an apex predator.

Jagatia’s playful curiosity and the professional insight volunteered by experts make for an easy listen. The episodes span between 30-40 minutes long, giving comprehensive but not overbearing answers to questions big and small, like: What’s the voice inside my head? Why do my armpits smell? What’s the fairest voting system? Why are seas salty? And how many flies have ever existed?
