Excellent exchange! As a pagan witch I believe the planet is a living entity...But there is only so much Mother can do without a little help from people. Here is that word, again...take responsibility for the immediate effect you can have. We can do some things to assist OUR survival on the planet...I see that as participating in the Divine.
But eventually, like all living things, the way we know the Earth will change and that will mean our species will either adapt/evolve or we will not be participants here any longer. Beyond that...just look at the universe around you--galaxies colllide, stars go nova...a billion things can occur. Yet these are all natural events... Nature, the Mother of us all.
