It's a good point. And it needs attention.
For all the useful talk about new products and innovative ways to cap emissions, there is little or no public discussion about the underlying cause of global warming — human population growth.
It matters enormously whether the world’s population in 2050 is 10.8 billion people or 7.8 billion people — the high and low projections made in 2006 by the United Nations. Consider how much less carbon pollution there could be in a world with 3 billion fewer people.
We’re going to need all the help we can get when it comes to reducing carbon emissions. It’s time to revive the global population movement that once enjoyed widespread bipartisan support here in the United States.
So why is there no serious discussion about the need for zero population growth? Why are we so fascinated with some as-yet-unproven technologies when a straightforward answer is at hand?
