VerifiedOperational Statistics Interpretation
Even a marvel of engineering like the Panama Canal must occasionally bow to the whims of a thirsty climate, as evidenced by 2023's parched 24 daily transits—a stark, revenue-shrinking dip from its pre-drought peak—proving that water, not concrete, remains the most vital component for global trade.
