La coupe est pleine.
Une visualisation originale (mais simpliste) qui tente d'expliquer la tendance au foisonnement de l'être humain. A quel moment le pick population sera-t-il atteint ? A quel moment la planète ne sera-t-elle plus suffisante pour nourrir autant de monde ? Quand le verre sera plein. Et quand il sera plein, il débordera.
"It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved
agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West.
As higher standards of living and better health care are reaching more parts of the world, the rates of fertility — and population growth — have started to slow down, though the population will continue to grow for the foreseeable future.
U.N. forecasts suggest the world population could hit a peak of 10.1 billion by 2100 before beginning to decline. But exact numbers are hard to come by — just small variations in fertility rates could mean a population of 15 billion by the end of the century."
