IMAGINE the year is 2060 and you have finally managed to get enough money to visit the 7th wonder of the world; the Victoria falls. As the guide leads you to your destination, you have high expectations. Before you realise it, you ground to a halt and hear the guide saying 'this is it'. You discover you are standing at a deep narrow steep-sided valley; a ravine. It is a lifeless place. No water cascading over masses of rocks. No lush greenery on the banks. Coarse dried up grass and grey-brown rocks are all that meet the eye.
