Thanks for this. We can pin it on one thing: Our disconnection from nature. We are in actuality ONE planet, but people are alienated, overcrowded. Fearful. We live in a pretense,(Einstein said delusion), that we are separate, that we don’t know that we are all one, inter-connected and inter -dependent.
Now with the danger of climate change and its refugees, we need to be one more than ever before. ANd we must be grateful, not hateful, to be so.
