For many decades, it was thought that the biggest crisis facing humanity was a rapidly growing population. Since then, demographers have come to realize that although a growing population creates challenges, world population growth is actually slowing down, to the point where we can begin to foresee a time when population growth will level off, and may in fact decline. Furthermore, it's resource consumption, particularly by the wealthiest 1 billion, that is driving the problems we face.
