Henry Ford tried to build an American industrialist utopia in the Brazilian jungle, “Fordlandia”, to secure a source of cultivated rubber for his cars.

Before the Columbian Exchange, there were no oranges in Florida, no bananas in Ecuador, no potatoes in Ireland, no coffee in Colombia, no pineapples in Hawaii, no rubber trees in Africa, no tomatoes in Italy, and no chocolate in Switzerland.

The rubber tree isn’t the only plant with rubbery sap, but it is the only one that produces more latex each time it is cut because the wound stimulates its rate of photosynthesis.

The cheetah has “semi non-retractable” claws (almost like dog claws) that work like the cleats on a football shoe to give the cheetah a lot of traction when running. The pads of most cats’ paws are soft, but the cheetah’s pads are hard kind of like the rubber on a tire. This also helps them grip the ground when they are running so fast.
