Because the Earth was very different. In the last one hundred years alone there have been more changes in the world than for thousands of years before. To experience all of those changes, one might choose to live multiple lives at the same time.
Another, and much more prosaic reason: Because there were not enough opportunities. After all, to incarnate as a human you need a man and a woman to give you the chance. As the population of the planet grows, it becomes more possible to be born on this Earth.
When the population of the planet was in millions, there were only millions of opportunities. Suppose there are one hundred million souls in existence (just an arbitrary number, I am not saying that there are that many) and there are ten million people one Earth. Well, only one in ten souls can incarnate at any one time. When the population grows to hundred million, then every soul can live exactly one life, or occasionally some may live two, but then others will have to wait. Now as the population grows, finally many souls may live more than one life. And as it keep growing more and more souls can live multiple lives.
