People are the problem.
Nature is blameless. It's just Nature.
People? We are a heady, tricky, complicated, often disappointing, sometimes wondrous Species. We possess a full trick-bag of tendencies and actions.
Most of the trouble in the world points squarely at Human Beings being Inhumane to other Human Beings. It's a general trend, a historical fact, a persistent narrative that rears it's ugly head in pretty much every realm.
Yikes. What is the remedy? Something like "There, but for the Grace of God, go I." You know, even if you don't believe in grace, or god, you can live like that. Try to put yourself in someone else's shoes.
We all know how tricky and complicated it is being Human. Figure it's the same for the next person too. Does that fix anything? Who knows. Worth a try. Lean to the Light.
