The Smithsonian has news for market timers:
Americans devour 7 pounds of avocado per person each year, compared to 1 pound on average back in 1989. Per capita consumption of avocados has tripled since the early 2000s, according to the USDA. Yet nearly all of these avocadosâ€”some 95 percent in the U.S. and about 80 percent worldwideâ€”are of a single variety: the ubiquitous Hass. Thatâ€™s especially crazy because … the pebbly, black-skinned Hass didn’t even exist a century ago.
Also this, which makes me wince to consider:
…mammoths and giant ground sloths would gobble the fruit whole and then travel long distances, before pooping out the seed and thus dispersing the trees.
