Quotes About Population

He is War. Divisiveness. Brutality. Heinous crimes against humanity. As an event on the battlefield, and the personification of it in a cage, he is all that and more. How many humans fell before the murderous hooves of this sly horseman of the apocalypse? Nearly half the world's population, by last count.

Populations that do not typically consume dairy products appear to exhibit lower rates of bone fracture despite consuming far less calcium than recommended.

Governments who manipulate population growth have two choices: making maternity pleasant, or making it inescapable.

It is an economic era that has come to be known as the Great Acceleration, thanks to its extraordinary surge in human activity. Between 1950 and 2010, the global population almost trebled in size, and real World GDP increased sevenfold. Worldwide, freshwater use more than trebled, energy use increased fourfold, and fertiliser use rose over tenfold.

Given that 80 percent of the world's population live in such countries, and the vast majority of their inhabitants are under 25 years old, significant GDP growth is very much needed, and it is very likely coming.

what determines whether or not we can actually move into its safe and just space? Five factors certainly play key roles: population, distribution, aspiration, technology and governance.

Out of sheer convenience, the vast majority of experimental studies, which have been conducted by academic researchers in North America, Europe, Israel and Australia, have used their own universities' undergraduate students as their subjects. As a result, between 2003 and 2007, 96 percent of people studied in such behavioural experiments came from countries that were home to only 12 percent of the world's population.

Around 40 percent of the world's agricultural land is now seriously degraded, and by 2025 two out of three people worldwide will live in water-stressed regions.

population matters, distribution matters just as much because extremes of inequality push humanity beyond both sides of the Doughnut's boundaries.

Population matters, and in an obvious way: the more of us there are, the more resources it takes to meet the needs and rights of all, and that is why it is essential for the size of the human population to stabilise. But here's the good news: although the global population is still growing, since 1971 its growth rate has been falling sharply.

In 1900, around 10 percent of people worldwide lived in cities; by 2050 around 70 percent of us will. Couple this proximity of city dwellers with worldwide communications transmitting news and views, data and ads, and what emerges is a dynamic global network of networks of human beings.

If population matters, distribution matters just as much because extremes of inequality push humanity beyond both sides of the Doughnut's boundaries. Thanks to the scale of global income inequality, responsibility for global greenhouse gas emissions is highly skewed: the top 10 percent of emitters—think of them as the global carbonistas living on every continent—generate around 45 percent of global emissions, while the bottom 50 percent of people contribute only 13 percent.

All five of these factors—population, distribution, aspiration, technology and governance—will significantly shape humanity's prospects for getting into the Doughnut's safe and just space, which is why they are all at the heart of ongoing policy debates. But they cannot bring about the scale of transformation required unless we also transform the economic thinking that we bring to bear.

In a finite world this means that the per capita share of the world's goods must steadily decrease.

Of course, a positive growth rate might be taken as evidence that a population is below its optimum.

The combined effects of mutation, natural selection and the random process of genetic drift cause changes in the composition of a population. Over a sufficiently long period of time, these cumulative effects alter the population's genetic make-up, and can thus greatly change the species' characteristics from those of its ancestors.

The speedy evolution of antibiotic resistance is not surprising, because bacteria multiply fast and are present in enormous numbers, so that any mutation that can make a cell resistant is sure to occur in a few bacteria in a population; if the bacteria are able to survive the change to their cell functions caused by the mutation and to multiply, a resistant population can rapidly build up.

Such a process of change will be especially likely if a population is exposed to a changed environment, where a somewhat different set of characteristics is favoured from those already established by selection.

Twenty-five miles to the south, the Sea of Galilee and its surrounding cities of Capernaum, Bethsaida and Tiberius were all within reasonable distance for common travel and economic activity. Caesarea Philippi was a multicultural nexus of ethnicity as well, with a thoroughly mixed population of Semites, Greeks and Romans from all over the empire.

A cubic meter of hazelnuts is sufficient to provide 10 percent of the annual energy needs of a mixed population of twenty people.

He let out a yell of joy. They danced round the room. Pressure of population was such that reproduction had to be strict, controlled. Childbirth required government permission. For this moment, they had waited four years. Incoherently they cried their delight.

The numbers seemed overwhelming. By the end of the summer, there were, in fact, four thousand more British soldiers in New York than the entire population of Philadelphia, America's largest city.

More than 130 million babies are born in the world every year.
