I was aware of the water conservation theme because of other reviews. Nonetheless, the scenery of the Grand Canyon is well presented from a personal perspective. Who can complain about well done scenery presentations of the Grand Canyon?
I enjoyed it, especially for some shots that match historical perspectives. They show what the Colorado River was like decades ago versus what it is today. The comparison is appropriately alarming: we are using up resources much faster than Nature replenishes it. Inaction will mean major disruptions to our lives.
I am writing this during a visit to Las Vegas. Seeing the abundant use of water by the hotel features (fountains, decorative canals, etc. They promote evaporation loss big time) help me realize we are barging ahead in this wasteful use of water and things must change, or scarcity will impose changes that we are unprepared for.
A must-see for those who like the Grand Canyon scenery and also want to find out more about the need to conserve.
