Démographie

An easy way to start a long, heated debate is to mention global population. Thomas Malthus famously ignited furious arguments in the eighteenth century when

Population ecologist William Rees, with the University of British Columbia's School of Community and Regional Planning, is reminding denizens of Earth that the planet can only support so many people. In his paper published in the journal World, he points out that many models have been developed over the years that show that only a certain number of animals (such as rats) can live in a given environment—they all show that at some point, a population correction occurs.

Population likely to peak sooner and lower than expected with beneficial results – but environment is priority

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.

Demographic statistics are among the most popular data Eurostat produces, and they are important for almost every area of policy. This new interactive publication Demography of Europe produced by Eurostat aims to bring these statistics to a new audience, providing clear visualisations and interactive features to help non-specialist users see what official European statistics can tell us about how the population is developing, ageing, and much more.

In 1968, the best-seller “The Population Bomb,” written by Paul and Anne Ehrlich warned of the perils of overpopulation: mass starvation, societal upheaval, environmental deterioration. The book was criticized at the time for painting an overly dark picture of the future. But while not all of the Ehrlich’s dire predictions have come to pass, the world’s population has doubled since then, to over seven billion, straining the planet’s resources and heating up our climate.
