Population explosion should concern us all

It’s official. The world population, yesterday, reached the seven billion mark. And the milestone has come in a record 12 years after the human population hit six billion, yet it took 123 years to reach two billion in 1927, from one billion in 1804.  Indeed, the world population is expected grow further, to eight billion by 2025, and to 10 billion before the end of the century. With this growth come enormous challenges, including increased pressure on limited resources, sparking fears of serious crises in the future.
