Sometimes reading about how global warming is melting the million years old glaciers, and due to that the climate is changing. Dead sea is drying up. Stronger heat waves are hitting us, dealing long term damage. And we're not doing anything to fix that. We're just busy in getting our own life together and making it better. We're doing nothing for the earth. In the end when all things will go dark, then we will remember that the earth doesn't belong to us, we belong to it.
