With global warming reaching new highs, Jon Holmes asked "does height matter?" in today's Big Debate.
Robert thinks not. "Why would we need heights?" he muses. "You don't need them to go up high or down low. You can reach anywhere these days."
Llewelyn disagrees. "Robert is looking backwards," he says. "Height is crucial for so many of our favourite pastimes, things like air travel, bungee jumping, effective Google mapping. Imagine a world with no clouds."
Even Jon's temper was tested, as this debate reached an entirely new level. Listen in above!
