Instead of giving your attention to what people think about the earth today, or what might be wrong with it, consider touching in directly with the earth itself. Put your hand in the dirt. Listen to the wind. Feel the coarseness of tree bark.
It's true that we need clean-ups and organizations, more whales and less plastic waste. But more than anything else, we need people who know how to enjoy the earth, right here right now.
If we could do this authentically as a nation, as a species, the ecological problems that currently seem so intransigent might end up resolving themselves rather easily.
In other words, don't focus on the problems of the earth. Focus on what you yourself, as a body and a brain, can feel is right - then give your energy to that.
