Wanting
The wheel of suffering in this world is fueled by wanting. Yet the ruling world culture, based in Capitalism, is motivated by wanting. As the human species spins more and more toward Capitalist supremacy, it will also spin more and more toward increased suffering. It will be that suffering which will eventually bring down Capitalism. We live on a rock in an atmospheric bubble in a vast and chaotic Universe. If we live responsibly in balance and harmony with the planet, we may indeed evolve to see our species outlive the life of the planet itself. This would be an evolutionary breakthrough of Universal merit. However, if we persist in wanting what we know is harmful to ourselves and our planet, we as a species will most likely regress or perish. Each person can contribute to human evolution by choosing to live in responsible balance through thought and meditation. The ability to do so is what makes us human.
