Will birth control solve climate change?
An additional 150 people join the ranks of humanity every minute, a pace that could lead our numbers to reach nine billion by 2050. Changing that peak population number alone could save at least 1.4 billion metric tons of carbon from entering the atmosphere each year by 2050, according to a new analysis—the equivalent of cutting more than 10 percent of fossil fuel burning per year.
Is birth control the answer to environmental ills?
Population growth, now at roughly 78 million extra people per year, is the don't-go-there zone of modern environmentalism and political discourse.
But let's go there for the moment: The biodiversity crisis.
