I have been traveling to Africa for 30 years, and throughout that time, people have lamented the decline of the continent’s wildlife. But the pace of destruction has accelerated to a horrifying extent. In 1966, the year that saw the release of the movie “Born Free,” there were 450,000 lion in Africa. Today, there are fewer than 20,000. Elephant and rhino are being decimated. By the latest estimate, the human population of Africa will double by 2050 to 2.4 billion.
