"Make Room! Make Room!"


"If you took all the people in the world and put them on a large set of scales, their combined mass would be about 300 million tons. If you then took all our domesticated farm animals—cows, pigs, sheep and chickens—and placed them on an even larger set of scales, their mass would amount to about 700 million tons. In contrast, the combined mass of all surviving large wild animals — from porcupines and penguins to elephants and whales—is less than 100 million tons." --Yuval Noah Harari, cited in [1] see Homo Deus: A Brief History of Tomorrow


"Humans on the Earth behave in some ways like a pathogenic organism, or like the cells of a tumour or neoplasm. We have grown in numbers and disturbance to Gaia, to the point where our presence is perceptibly disturbing ... the human species is now so numerous as to constitute a serious planetary malady. Gaia is suffering from Disseminated Primatemaia, a plague of people." --Healing Gaia (1991) by James Lovelock, p. 153

In demographics, the world population is the total number of humans currently living, and was estimated to have reached 7.6 billion people as of May 2018.

World population has experienced continuous growth since the end of the Great Famine of 1315–17 and the Black Death in 1350, when it was near 370 million.

The highest population growth rates – global population increases above 1.8% per year – occurred between 1955 and 1975, peaking to 2.06% between 1965 and 1970. The growth rate has declined to 1.18% between 2010 and 2015 and is projected to decline further in the course of the 21st century.

Total annual births were highest in the late 1980s at about 139 million, and as of 2011 were expected to remain essentially constant at a level of 135 million, while deaths numbered 56 million per year and were expected to increase to 80 million per year by 2040. The median age of the world's population was estimated to be 30.4 years in 2018.
