Hard Ecology, Soft Ecology, and Ecosystem Integrity

What you take as your starting point depends on where you want to go. If you want to sail due south to the Dry Tortugas, then you start with plenty of fresh water, some food, a good navigational system, and arguably a ship-to-shore radio for the long trip. But if you want to sail due west to nearby John’s Pass, then you might need some fresh water, but no food, no sophisticated navigational system, and no radio. How you begin a journey depends on where you want to go. So it is with environmental ethics.
