"Never let your sense of morals prevent you from doing what is right" I. Asimov In the outstanding film “A life on our planet”, Sir David Attenborough tells us which actions we need to implement to avoid a future catastrophe. His plan is feasible and affordable: we already have all the knowledge and technology required … Continue reading ‘A Life on Our Planet’: Attenborough’s recipe and human reluctance — Chronicle of a failure foretold
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 … Continue reading Boiling Frogs
Since the fall of the Eastern bloc, both Ukraine and Romania have seen their populations shrink. Driven by rural to urban migration, low fertility rates, and substantial emigration, the depopulation in the Danube Delta region has opened up large areas to rewilding efforts. With a history of irrigation and altered river dynamics, restoration and reintroduction … Continue reading A Decreasing Population Furthers Rewilding Efforts in Romania’s and Ukraine’s Danube Delta
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 … Continue reading Earth overshoot day and population
In recent years, migrants fleeing overpopulation and lack of economic opportunity have been rebranded as “climate refugees” by corporate media looking to justify open borders. But expanding migration will simply fuel continued population growth, leading to greater resource consumption, higher greenhouse gas emissions and worse climate change. It's a Ponzi scheme perpetuated by falsehoods that’s … Continue reading Climate refugees or overpopulation escapees?
A major media storm has erupted about a new scientific paper published in the Lancet claiming that global population will soon peak and decline. The prospect is met with doom and gloom, rather than jubilation. But Jane O’Sullivan finds many reasons to challenge both the claim and its assumed economic threat. By escalating unfounded fears … Continue reading Will global population peak below 10 billion?
In his new book A Planet of 3 Billion, Christopher Tucker presents a vision of a future world inhabited by 3 billion people, compared to 7.8 billion today. Inspired by Joel Cohen’s 1995 book How Many People Can the Earth Support? Tucker sets out to answer exactly this question. The ecological destruction caused by humanity … Continue reading New book argues for a sustainable world with 3 billion people
Covid-19 continues to take a great toll on societies around the world. As we struggle to respond appropriately, our societies can emerge ecologically and socially stronger—provided we learn the important lessons this tragedy has to teach us. by Kelvin Thomson In Australia, and I suspect in many other countries as well, there are three key … Continue reading Lessons from a global pandemic
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 … Continue reading Overshoot day: the other side of the coin
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 … Continue reading New EU Biodiversity Strategy Fails to Address a Key Component of the Biodiversity Crisis – Human Numbers
In the Croatian alps, declining human populations have gone hand in hand with expansions of protected lands and resurgent wildlife populations. Large predators are finding their way back to the region now that the anthropogenic pressures have lightened, and rewilding efforts have ensured the comeback of both mountain-dwelling herbivores and large grazers on the adjacent … Continue reading Fewer People = More Wild Nature in Croatia’s Velebit Mountains
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 … Continue reading Drawdown: a review of the Review
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 … Continue reading Can Human Use Be Combined with Biodiversity Protection in the Tropics?
In recent years, some environmentalists have argued that increasing population density is the key to creating sustainable societies. COVID-19 suggests they are mistaken. When increasing density becomes a substitute for setting limits to human numbers and demands on nature, environmental conditions deteriorate. And as usual, poor people and other species wind up paying the price. … Continue reading A lesson from the COVID-19 pandemic on the perils of density
With decreasing populations in parts of rural Europe and marginal agricultural lands being abandoned, Europe is in a strong position to return land to wilderness. At the northern end of the border between Poland and Germany lies the Oder delta, where rewilding efforts on land and in water have contributed to a quick recovery of … Continue reading Restoring Abandoned Land in the Oder Delta Gives New Opportunities for Wildlife in Germany and Poland
This week, we reprint a valuable article by Professor Alon Tal, published in The Times of Israel on 25 March, on the connection between overpopulation and the coronavirus pandemic. Professor Tal explains the relationships between population density, human encroachment on natural areas, and disease transmission, and also the situation in Israel, a densely populated country. … Continue reading The disconcerting association between overpopulation and the COVID-19 crisis
Fifty years ago, in his 1970 Nobel Peace Prize acceptance speech, Norman Borlaug said: “There can be no permanent progress in the battle against hunger until the agencies that fight for increased food production and those that fight for population control unite in a common effort.” Borlaug was insightful, but also a genuinely humble man. … Continue reading From Population to Production: Scientists’ Changing Views on How to Feed the World
