Episode #2: Earth moving
America moves 2 inches each year. So how much has our house moved?
Our house has moved 44 inches since we have lived here. That is almost 4 feet.
Since the house was built in 1968, it has moved 8.5 feet!
No wonder these houses have cracked foundations and broken Drain stacks!

On the Galapagos islands whalers would capture giant tortoises and put them on board the ships for food on long voyages. Some ships would take as many as 700 on one hunting trip. They pretty much drove the giant tortoises to extinction as they took over 300,000 of them.
