โWhen our genes could not store all the information necessary for survival, we slowly invented brains. But then the time came, perhaps ten thousand years ago, when we needed to know more than could conveniently be contained in brains. So we learned to stockpile enormous quantities of information outside our bodies. We are the only species on the planet, so far as we know, to have invented a communal memory stored neither in our genes nor in our brains. The warehouse of that memory is called the library.
A book is made from a tree. It is an assemblage of flat, flexible parts (still called โleavesโ) imprinted with dark pigmented squiggles. One glance at it and you hear the voice of another person - perhaps someone dead for thousands of years. Across the millennia, the author is speaking, clearly and silently, inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people, citizens of distant epochs, who never knew one another. Books break the shackles of time, proof that humans can work magic.โ

The reason we think dandelions are weeds is because of a 1950s marketing campaign.
Dandelions, native to Europe and Asia, were brought to North America in the 1600s by European colonists who grew them deliberately.
Every part is edible. The leaves are a salad green, the flowers were made into wine, and the roots were roasted as a coffee substitute and used medicinally for liver and kidney conditions for thousands of years. They were a kitchen-garden staple well into the 1800s.
The shift happened after World War II, when 2,4-D (originally developed for chemical warfare research) was approved as a residential herbicide. Companies like Scotts built the modern lawn-care industry around the idea that a perfect green lawn meant zero broadleaf plants.
Dandelions, being bright yellow and resistant to mowing, became a visible enemy, and the campaign worked. By the 1970s, "dandelion-free" was synonymous with "well-kept."
They aren't native, but they aren't doing significant ecological harm either. The herbicides used to kill them, on the other hand, kill bees, contaminate groundwater, and have been linked to non-Hodgkin lymphoma in humans.
If you hate dandelions, it's most likely due to a marketing campaign that ran before you were born.
@StJimmySkywalk1@TheStingisBack Always thought it was โlawโ but love is great. Definitely NOT celebrate the lord. There no jesus in Star Wars.

@messedupcars We just found out why. They used volcanic rock, or something like that, mixed into their concrete, which self healed when it rained. Amazing stuff.
