Yesterday the human population reached seven billion.
“Population is a complicated topic. But we wanted to do it in a way that gives readers room to think. We spread out our coverage over a year, with articles that take deep dives into specific issues—demographics, food security, climate change, fertility trends, managing biodiversity—that relate to global population. Our reporting is collected here. Feel free to explore and share your thoughts on twitter at #7billion.” – National Geographic Special Series: 7 Billion
