By Zsolt … Continue reading More and more people living on the planet is cause for concern
Costa Rica is a country of exceptionally rich and well-protected biodiversity. It is a solid democracy where people live long, relatively healthy and happy lives while leaving a small ecological footprint. Together with its good and improving environmental performance and overall well-being, the country is characterized by a below replacement fertility level, the lowest in … Continue reading Family Planning for forests and people – the success story of Costa Rica
A new United Nations report on biodiversity was released this week with much media coverage. Scientists and mainstream journalists seem unwilling to address the fundamental drivers of biodiversity decline, but public response suggests transformative change is gaining traction. By Jenna Dodson This week, many media outlets are covering the pre-release of a new United Nations … Continue reading Civilization extinguishing biodiversity, where are the viable alternatives?
In the 1960s and 70s, South Korea experienced one of the fastest fertility declines in the world, halving the number of children born per woman from over 6 to less than 3 in just 18 years. In large part, this was due to early government recognition that fertility reduction is a component of development, a … Continue reading Low fertility in South Korea: a springboard for social change and conservation
By Phil Cafaro Steve Irwin. Errol Flynn. The Sydney opera house. Kangaroos. Wombats. Here at TOP, we hardly need new reasons to love Australia. Yet last week, we came across two more: articles by Dr. Harry Recher and Dr. Freya Mathews that we somehow missed when they were first published several years ago. They do … Continue reading Two more reasons we love Australia
By Massimo Livi Bacci Four population-driven threats to space If from abstract principles and paradigms of my previous article (Malthus, forever?), we turn to the real, contemporary world, we may say that the rapidly expanding world population also has other consequences – beyond the reduction of “pristine” space – that may adversely affect the quality … Continue reading Four compelling reasons to fear population growth
By Patrícia Dérer The primary cause of the global biodiversity crisis is human-induced alteration and loss of natural habitats1. One of the most important causes of habitat destruction is housing growth, manifested both in rural and urban sprawl. The impacts of housing growth derive from both building human dwellings and their associated infrastructure such as … Continue reading Housing growth threatens biodiversity – are we ignoring fundamental causes?
By Jane O’Sullivan Why would an organisation dedicated to protecting natural areas and to saving wild animals turn its back on arguably the biggest threat? WWF used to highlight human population growth, but not anymore. Populations of wild animals have declined, on average, by 60% since 1970. This alarming statistic was announced in WWF’s 2018 Living … Continue reading WWF Living Planet Report 2018 – “aiming higher”, but not on target
TOP believes there is no better video presentation on the consequences of overpopulation than Sir David Attenborough’s RSA (Royal Society for the encouragement of Arts, Manufactures and Commerce) President's Lecture. The well-known British naturalist delivers an impressive speech explaining why population growth is a multiplier of every environmental problem. Given that the Earth has physical limits, “sustainable … Continue reading People and Planet – Sir David Attenborough’s take on overpopulation
The Overpopulation Project announces the Human Overpopulation Atlas, written by João L.R. Abegão. The Atlas is the extended masters thesis of the author in Ecology and Environment at the Department of Biology of the University of Porto in Portugal. This broad review work synthetizes knowledge about the past, present and future of human overpopulation. In … Continue reading Announcing the new Human Overpopulation Atlas
Our blog about Factfulness led to comments, discussion and finally a response from one of its authors (note: the book is written in Hans Rosling’s voice and is the joint work of Hans Rosling, Ola Rosling, and Anna Rosling Rönnblad; Hans Rosling died in February, 2017). Ola Rosling states that he welcomes our criticism and … Continue reading Can the book “Factfulness” be improved?
by Jenna Dodson How much of the planet should we leave for other forms of life? How much of the planet can the 7.6 billion present-day human inhabitants utilize without sacrificing the well-being of future generations? These are important questions with far reaching implications for all species, Homo sapiens included. People are placing unprecedented demands … Continue reading Space for Nature
By Patrícia Dérer Thirty countries around the world have declining human populations. With the exception of Japan, these are European countries that, along with the rest of Europe, have successfully undergone the “demographic transition”. Impressive achievements in health care, education and economic development have resulted in lower child mortality and longer life expectancy, leading to … Continue reading Rethinking depopulation and land abandonment – the opportunity of rewilding
by Frank Götmark This year Hans Rosling, Ola Rosling, and Anna Rosling Rönnblad (below the “Rosling team”) published “Factfulness” (Note: H.R. died in February 2017.) As the book to a large extent is about global population and as Bill Gates is giving free copies of it to college graduates in the US, we need to … Continue reading ”Factfulness”: a more accurate title for this new book would have been ”Selecting Facts to Make You Happy”
By Patrícia Dérer We are entering the sixth mass extinction of life on Earth, the first to be caused by humans1. Extinction rates are several orders of magnitude above normal. Humanity has managed to exterminate more than 300 vertebrate animals in modern times, the IUCN estimates that half the globe's 5,491 known mammals are declining in … Continue reading A key driver of the biodiversity crisis is poorly evaluated: population size
