Water, that great equalizing and dissolving force, can at the same time be essential and detrimental. As it pervades all life, it is needed by life. But then as it dissolves and breaks everything down and incorporates everything into it, it succeeds at eroding those passes at continuity such as housing and walking paths. What one needs must also be held at remove.
But then to act too strongly to protect against water, say to lay down a suffocating cover of concrete to ensure that nothing breaks down, is to deny the percolation of water into the ground where it is needed, or otherwise, the water moves somewhere else, where it eventually gathers strength and floods and overwhelms.
So nothing can really be absolutely dominated or subsumed. What is to be influenced must also influence in turn.
