The variety of folks on the planet has hit an enormous milestone at 8 billion, however fertility charges are falling quick in lots of nations, which suggests planning for an older inhabitants

THERE are quickly to be 8 billion of us and counting. Yet whereas the world’s inhabitants continues to be rising quick total, in lots of nations, the numbers are declining or will do quickly.
