Today’s global population is 6.5 billion. It took the entirety of human history until 1830 to reach the first one billion people in population, but at present it's taking us a mere 12 or 13 years to add each new billion. Our annual growth is 80 million people. This explosive growth in the sheer numbers of people consuming resources, energy, and water, producing waste, and contributing to greenhouse gas emissions is without historical precedent and significantly impacts Earth's carrying capacity.
