The tale of a lost forest

This myth has been passed down by generations of Elves and is generally used as an example by non-humans to show the innate problems with mankind.
The myth goes as follows:
Long long ago there was a forest near the ocean inhabited by a tribe of elves. These elves lived in harmony with the forest and all its creatures and where hospitable to all. Then one day from the ocean a lone human arrived malnourished and weak. The elves had never seen somebody like this before but they where kind and gave the human all he could wish for as there honored guest. After a few days the human satisfied left, going back across the sea.  A couple months later some more humans arrived to the forest. The Elves once again showed them nothing but kindness and when they wishes to stay in the forest the thought the humans how to hunt and foerage without damaging the forest. The Elves where patient and forgave the Humans for the many mistakes they made helping them improve. Months later more humans arrived and the Elves once again did there best to accommodate. Then more arrived. And then yet more. The Elves knew that this forest could not sustain this many people. So they asked some of the humans to travel elsewhere. They knew other elves who could help them in different forest and they would do everything they could to help them in there journey. This greatly upset the Humans who chastised the Elves for being greedy and not willing to share there home. The Elves tried to explain that the forest simply couldn't sustain this much life and that there was no other ways. The Humans where hearing non of it. Decreeing that if there is such a problem why don't they move away instead. In there anger the Humans started to build there own settlement cutting down swats of forest for lumber and hunting down entire colonies of animals without keeping preservation in mind. After much failed diplomacy the Elves decided they could not let there forest be destroyed like this and attacked the humans after repeatedly warning the Humans that if they did not stop they would be left no other option and pleeding for them to listen to reason. The Humans saw this as an act of unwarranted aggression and decreed the Elves heartless monsters even after all that the Elves had done for them. The Elves did manage to drive of the humans but a month later another group of humans arrived from the sea with spears at the ready. They managed to fend of this attack but every month more humans would show up in greater numbers each time. Eventually these Elves where driven out of there ancestral home and forced to flee. 
The forest they once resided in is now nothing but dirt, having been completely consumed by the humans.
