Reply to comment by triffid_hunter in so why don't earth slow down do to the drag of the water created in the tidel forces by the moon? by SnurrDass

Ok, but then the tide forces get weaker, an less momentum will be transfered, due to a larger orbit, so in one point earth and the moon will reach equilibrium, is life on earth then sustainable?

Life on earth is already sustainable. The moon and earth will not reach the equilibrium you’re hoping for, but that’s not really related to sustainability.

Unfortunately, if you’re looking for perpetually life sustaining conditions, you’re out of luck. The sun is the problem. Stars have a life cycle and they don’t end well for life on their planets.
