Research, population growth

“UN demographers are now projecting anywhere between 6.2 billion and 15.8 billion people at the end of the century.” – Source

“We can lower birth rates by assuring that women become pregnant only when they themselves decide to bear a child.” – Source

“Just 10,000 years ago, there were one million of us. By 1800, just over 200 years ago, there were 1 billion of us. By 1960, 50 years ago, there were 3 billion of us. There are now over 7 billion of us. By 2050, your children, or your children’s children, will be living on a planet with at least 9 billion other people.” – Source

“The 10 warmest years on record have occurred since 1998.” – Source

“We hear the term “climate” every day, so it is worth thinking about what we actually mean by it. Obviously, “climate” is not the same as weather. The climate is one of the Earth’s fundamental life support systems, one that determines whether or not we humans are able to live on this planet.” – Source

“Our emissions of CO2 modify our atmosphere. Our increasing water use had started to modify our hydrosphere. Rising atmospheric and sea-surface temperature had started to modify the cryosphere, most notably in the unexpected shrinking of the Arctic and Greenland ice sheets. Our increasing use of land, for agriculture, cities, roads, mining – as well as all the pollution we were creating – had started to modify our biosphere. Or, to put it another way: we had started to change our climate.” – Source

“Demand for land for food is going to double – at least – by 2050, and triple – at least – by the end of this century. This means that pressure to clear many of the world’s remaining tropical rainforests for human use is going to intensify every decade, because this is predominantly the only available land that is left for expanding agriculture at scale. Unless Siberia thaws out before we finish deforestation. By 2050, 1bn hectares of land is likely to be cleared to meet rising food demands from a growing population.” – Source

“Meanwhile, another 3 billion people are going to need somewhere to live. By 2050, 70% of us are going to be living in cities. This century will see the rapid expansion of cities, as well as the emergence of entirely new cities that do not yet exist.” – Source

Food: Population growth has forced more than 20 water and/or cropland-scarce countries to import grain, making them vulnerable to food-price volatility in the international marketplace. To meet the demands of the future, we must double world food supplies by 2050, if not sooner, all while reducing our impact on the environment, according to Jon Foley of the University of Minnesota.” – Source

“Future Growth: By 2050, the UN says global population could range anywhere from 8 billion to 11 billion – and where it ends up depends in large part on the status of women in developing countries. “Even if fertility rates remain constant at current levels (which is unlikely), developing regions would grow from 5.7 billion in 2010 to 9.7 billion in 2050, but the total population of developed countries would remain essentially unchanged,” writes Madsen.” – Source – The problem isn’t space its sustaining resources for the 7 billion.

“We are already on an unsustainable trajectory of deforestation, water pollution and scarcity, depletion of soils, and species loss, and yet we must find even more food, water, and energy to provide for our continually increasing numbers, 97 percent of whom live in developing countries.” –
