Most humans are unable to come to grips with the fact that one day they will die, so have invented many many stories of an everlasting after-life. That way of thinking has created a false alternative to our only life on the only planet we know that supports life and has given us agency to ignore the destruction we are causing.

imho we have to accept our certain mortality before we can accept the possible mortality of the planet.
