This wall chart is part of the World of 7 Billion, an educational campaign to help educators, and students, mark the addition of Earth's 7 billionth member. On one side of the wall chart you'll find a timeline of historical events, inventions and social movements that have affected birth and death rates over the past 200 years, bringing us to 7 billion in 2011. The other side of the wall chart uses a variety of colorful infographics to show the challenges we face as a growing global family - from meeting our basic human needs to the delicate balance of natural ecosystems.
