Too many people consuming too much
by N.R. Baker According to the well-known metaphor, if you were to put a live frog into boiling water, it would – very wisely – leap straight out again. However, if you put the frog into tepid water that was then brought slowly to the boil, the hapless creature would be cooked before it even…
Too many people consuming too many resources and generating too much waste: that’s why humanity keeps pushing deeper into ecological overshoot. On Earth Overshoot Day, let’s not forget the P factor. by Lucia Tamburino & Philip Cafaro Every year on Earth Overshoot Day, a table like the one below makes the rounds, showing the number…
Every year on Earth Overshoot Day, a table becomes very popular, showing the number of Earths needed to be ecologically sustainable if all the people in the world had the same ecological footprint as the average citizens of various countries. This is computed by fixing the world population at the current value and varying the…
The latest biodiversity strategy from the EU Commission makes some good suggestions for increasing protection for Europe’s dwindling biodiversity. While new, ambitious targets for protected areas and ecological restoration are welcome, the document fails to point out the central role population size will play in whether they are achieved. Through allowing the EU’s human population…
By Jane O’Sullivan Hats off to Paul Hawken, the environmentalist behind Project Drawdown. Three years ago, he published a best-selling book, ‘Drawdown: the most comprehensive plan ever proposed to reverse global warming’. The concept was brilliantly simple. It stripped away the complexity of how to respond to climate change, by cataloguing the hundred most impactful…
by Philip Cafaro and Jane O’Sullivan A full-length feature film from Michael Moore and long-time collaborator Jeff Gibbs, first screened last year, has just been released for free viewing on YouTube, garnering over 3 million views in less than a week. While flawed in several ways, it nevertheless makes a valuable contribution to the public…
With the ongoing tropical biodiversity crisis, protected areas play an important role for many species. But strict protection can harm local human communities that are reliant on the lands around them for survival. In addition, resources are often lacking to prevent illegal exploitation or hunting in strictly protected areas. Community-managed reserves have been suggested as…
Many readers of our blog probably see no problem with “overpopulation,” but we sometimes get negative responses when we use the word, even from colleagues who largely share our views. Why is this so? How should overpopulation best be defined? By Frank Götmark, Jane O’Sullivan and Phil Cafaro In contrast to other organisations dealing with…
Too often, it seems, matters of population are overlooked in discussions of global sustainability. And this is true, despite some rather obvious points: A world of, say, 5 billion people is more likely to be sustainable than one of 10 billion; and a world of 1 billion is likely more sustainable still. All things being…
Mahatma Gandhi said: “Earth provides enough to satisfy every man’s need but not every man’s greed.” What is then the “right” lifestyle, which we all should adopt to be sustainable? It depends on how many people there are on the Earth. Sustainability does not depend only on lifestyle, but also on how many people share…
By Patrícia Dérer Sri Lanka and the Indian Western Ghats (also known as Sahyadri Mountain Range) make up one of 36 Biodiversity Hotspots. These areas are the Earth’s most biologically rich—yet threatened—terrestrial regions; they were designated in order to preserve the most species. The Western Ghats belong to the eight “hottest hotspots” based on their…
