The first one is a summary and review of the book The Hidden Life of Trees by Peter Wohlleben:
“Why do they share food with their own species and sometimes even go so far as to nourish their competitors? The reasons are the same as for human communities: there are advantages to working together. A tree is not a forest. On its own, a tree cannot establish a consistent local climate. It is at the mercy of wind and weather. But together, many trees create an ecosystem that moderates extremes of heat and cold, stores a great deal of water, and generates a great deal of humidity. And in this protected environment, trees can live to be very old.”
The second article is a Ted Talk describing the newest research into why a trait limiting reproduction doesn't disappear, but instead is seen throughout history, across cultures, and in most species of animals.
Both articles point to our need for each other and the more diverse we are the stronger we are.
