Avocados nearly went extinct

Avocados used to be eaten by large mammals, who would carry the avocado seeds and spread them to new areas after passing through their digestive tracts. But as these large mammals began to go extinct, it caused the potential problem of not having a way to spread to new areas. Humans started to inhabit the areas where avocados grew at about this time, and because they had the capability to cultivate and grow food, they enjoyed avocados and added them into their diet, thus preserving this fruit that nearly went extinct.
