A Global Community of over Seven Billion
The global human population has crossed the seven billion mark today. Significantly, it took just over two centuries for the global community to grow seven times of its size from around one billion at the beginning of the 19th century to over seven billion in 2011. We may well double ourselves over the next century. A global community of over seven billion. Remarkable progress in all spheres yet many challenges ahead.
