What a thrill on our last drive in the Serengeti to find and observe these beautiful creatures – a mating pair of leopards in an unusually-formed acacia at dusk. Their partnership is unmistakable, their collaboration is a life saver for both of them, their link to complexity, diversity and complex adaptive systems is both unmistakable and inspiring. I can’t imagine losing these shy creatures because there are too many humans on the planet resulting in more and more habitat loss. As eco-tourists, are we helping or hindering? Hard to know!
