In 1987, Harvard graduates were asked to explain why we have seasons in the documentary A Private Universe. Many couldn’t.
So, are you smarter than a Harvard grad?
Take a moment to try to explain how we have different seasons. I’ll give you a hint, it has to do with Earth and the sun.
Alright, ready to learn (or confirm)?
Your banana and my banana are related.
Well, both bananas are actually the same. They are clones of each other (from identical plants). This means we can cultivate exactly which banana we want. (Ever noticed how there are no seeds in bananas? That’s thanks to the monoculture crop.) There are over 1,000 varieties of bananas, but the kind we most often buy is the Cavendish.
What could a downside be of an identical banana crop?
You’re sitting on the bus looking at your phone, catching up on the latest news. You realize it is your stop and quickly rush off, likely hitting someone in the head with one of your five bags (so sorry).
You tap the outside of your pocket to check you have your phone because you are a millennial. It’s not there.
You’re walking through a forest in northern Canada, the United States, Asia, or Europe, and you see something scaly and charcoal-like on the side of a birch tree. You approach cautiously — what could this growth be? You pull out your foraging knife or hatchet to cut off the growth and save it for later because you are sure it will make a tasty tea.
And you may be right if you cut off the parasitic fungus chaga (Inonotus obliquus).
