Série especial da National Geographic sobre os 7 bilhões
Population is a complicated topic. With the worldwide population slated to top 7 billion in 2011, we decided it was one we needed to tackle. 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.
