Start your review of Countdown: Our Last Best Hope for a Future on Earth?
The most serious question in history. How can we humans go on?

4 1/2

Alan Weisman is a practicing and teaching journalist. He’s received several awards, and written five books, the most popular being the 2007 The World Without Us. Countdown is Weisman’s attempt to bring humans back into the picture, by reporting on how the stresses being exerted on our planet could all be lessened by a single remedy – a lowering of the human birth rate, and eventually a lowering of the human population (without co

A marvellous investigation of the world's populations, and the resources available to us. Before reading this I had a rather woolly idea that the world was over-populated, and that we were over-consuming our resources - but the reality is much more complex than that, and the situations vary strongly from country to country. I haven't changed my opinion, but it has been bolstered by a wealth of fascinating information. Also Weisman doesn't only tackle countries with growing populations, but also

7th Favorite Read of 2015

This may not be the best book I read this year but it will likely be the most important. Mr. Weisman travels to twenty countries over five continents and interviews scientists, economists, religious leaders, politicians, activists, and everyday people around where our world is headed.

Initially this book frightened me, and made me feel disgust and anger towards humanity and myself for the state that our beautiful earth

Alan Weisman has written a masterful, detailed, and well-researched account of the problem that increased population of human beings is bringing to our planet. He begins with a shocking report of how Israelis and Palestinians are destroying the land which they claim to love through their unceasing birthrate. It is painful to read. Next comes Mexico, Uganda, Great Britain, and country after country, including the Vatican, showing how each is culpable in helping to destroy our planet making it unl ...more

Alan Weisman who wrote the popular The World Without Us looks at world population growth and its impact. He goes beyond the statistics and dire forecasts, taking us to communities around the globe. We see the complexity of dealing with rapidly increasing populations and environmental degradation. Each situation is different; some are success stories and some are communities trapped in downward spirals. Entrenched power, greed and tradition are difficult to overcome, but NGO’s, committed governme ...more

I received this book through a goodreads giveaway.

I do not consider myself a particularly avid environmentalist and this is not the type of book I would typically pick up for myself, but I'm really glad I read it. One of the highest compliments I can give a book (especially non-fiction) is that I find myself talking about it with other people, and that has been the case with this book many times already.

I won this book from the firstreads giveaway. Thank you, goodreads, for the opportunity to read this book.


First, let us take a look at Alan Weisman's style in Countdown:

When I begin to read a non-fiction book that introduces a new idea that is meant for an audience who is ignorant about said idea, I expect a certain amount of ease of reading. That is not to say it should be simplistic, but the ideas must be presented in such a way that a wide range of people can understand it.

we humans, despite our natural aptitude for mathematics, seem to have an arduous time making sense of concepts that involve very large numbers. unfortunately however, abstract notions have absolute consequences, whether anticipated or otherwise. although it took until the early 1800s for global population to reach its first billion, it has doubled twice since the year 1900, giving us now some seven billion people worldwide. around the year 2050, the united nations estimates that there may well b ...more

This started with a lot of promise. It included a lot of examples of how extremely high fertility rates in developing nations have been harmful to mothers and children and the environment, and how some countries have changed their high fertility rates. But I felt that the book overall left something to be desired. It spent a lot of time talking about the problem, and not as much talking about solutions. It did talk about how some countries lowered their fertility rate, but it didn't spend much t ...more

I won an ARC of this book from Goodreads and was very excited to receive it. I was not disappointed. Having really loved Weisman's previous book, The World Without Us, I was very interested to read his follow-up book, about overpopulation, and how the world could survive with us. I highly recommend this book to everyone, to get a firm grasp on the issues that we face, not just specifically about overpopulation, but about how utterly interconnected so many of our issues are -- women's equality, c ...more

A sobering look at the population woes that beset the human race and how various cultures are approaching the issue. Truly this is a work that is not to dismissed when you consider the population trajectory that we're on and the problems inherent that we're already trying to deal with. Multiple times throughout this book, Weisman reminds us that we're on course to have 10 billion (possibly MORE!) people o

Weisman's latest book, Countdown, takes a look at the point at which human population (or overpopulation) and the environment (or overconsumption) converge. That point is incredibly frightening, because from there on we're looking at famine and a lot of suffering that we, as humans, might avoid simply by controlling population.

There's quite a bit of discussion about which countries are being responsible or irresponsible re: population growth and environmental sustainability. It's been particula

Reading this book is like reading a long, long, long National Geographic article on overpopulation (without the pretty pictures). Weisman takes us all over the world, from Israel to Thailand to India, to show us how people are dealing with exploding populations.

His solution? Have fewer babies. While it's hard to disagree with the numbers, and it is definitely true that our Earth can't handle us all having nine kids, I did wish there was more emphasis on overconsumption—because that's what I tru

The world's population is increasing at the rate of one million people every 4 1/2 days. A terrifying fact and one that's hard to get your head around. Weisman's unflinching look at how unfettered population growth is impacting the earth's ecosystems around the globe, and the efforts of committed individuals and organizations to confront the inevitable is a conscious raising masterwork of journalism.

This book is one of the best that I have read that deals with the overpopulation issues that we are facing. Not only does it talk about the general subject , but Weisman examines what is happening in different countries around the world. This multicultural approach is one of the biggest strengths of the book, as it reduces the amount of ethnocentrism and shows what approaches have worked before and what is preventing some cultures from reducing their birth rates to more manageable levels.

Disclosure: Won an advance copy on FirstReads. Also an unabashed, hopelessly biased fan of Weisman's The World Without Us.

Powerful. And among the best and most effective epilogues I've ever read. I don't think it would do the reader a disservice to read it first (and then again at the end). It sets the stage for the book's argument, which an unnamed woman in the epilogue sums up pithily: "There is not a single problem on Earth that wouldn't be easier if there were fewer people."

I wanted to love this book. I think The World Without Us is a masterpiece of imagination and science, and strong writing. So I was impatient for Countdown. And it does start promisingly as Weisman assesses what is undeniably a crisis. In fact, it is a crisis of unimaginable proportions: the planet cannot furnish 7 billion people with the resources to live sustainably, never mind the 10 billion it will soon be home to. ("Sustainably" is a word that has been watered down with misuse; in this conte ...more

Well-told and fascinating anecdotes from the author's travels. However, I was disappointed that there was no real attempt to quantify the earths carrying capacity. Although the whole book is dedicated to showing how bad our population is, it makes no serious efforts to offer solutions, other than a half-hearted reference to not-yet-available male contraception innovations. And although Paul Ehrlich points out that consumption is increasing faster than population and is therefor even more problem ...more

An important book, and the amount of "human interest" detail --too much for my taste-- will undoubtedly result in it being read more widely than a shorter, more focused on the science, book would have been. But I had hoped for much more on how a steady population world/economy could work, and, except for a too-brief chapter on Japan's situation, there was very little. He does do a good job of making clear the grave danger the world faces and notes that his friend Paul Ehrlich believes that there ...more

Goes around the world examining various country's environmental and population strategies (links population with environmental degradation). Lots of information showing different strategies to ameliorate environmental damage and to control/not control population/birth rates. Sometimes gets tedious with too much information. Makes the argument repeatedly and over and over again and on and on that having too many people is linked with environmental damage.

"You have to finish reading Countdown before we get pregnant," Mike sez.

I do not.

"Now we're having a baby and you haven't even finished Countdown!"


Guess what? Population crises suck. Will the same world be around for Tugboat in 2050? Probably not, but I don't see a Cormac McCarthy scenario either. (In Mike's version of the events, I am Charlize Theron.) That's why I continue to give money to fund abortions.

A definitive compilation of things to know about our world, its populationand the dynamics between them. And a thorough study on how we should make the world liveable for every one. Being Fewer, better, healthier. Education, and family planning must lead the way. Let's hope the message will be heard.

If Earth’s enormous human population is a threat multiplier, and raising death rates is not an acceptable answer, how do you reduce human population to avoid catastrophe? While answering this question, author Alan Weisman summarizes the 20th century’s human population explosion in ecological terms, and points out the plethora of literature indicating a grim future for humanity. Weisman’s argument acknowledges the traditional reaction to population control as inequitable. However, he points out t ...more

This is one of the more powerful books I’ve read in a while. Weisman got right to the root of the problem of overpopulation that leads to overconsumption of Earth’s resources. There was some repetition when describing some of the many countries and our ability to rein in the number of children with the use of birth control. He describes a lot of countries that I would have ever crossed my mind had he not mentioned them. It seems that educa

Loads of information on the effects of over-population, but I found the book over long and repetitive. As much as I enjoyed "The World Without Us" for the informative and imaginative way it showed how the world would change without a human presence, I found "Countdown" a bit of a difficult slog to get through. Why? Maybe the book just wasn't my cup of tea, and I'm sure many readers here will disagree with my assessment of the book, but I

The author of the excellent thought experiment titled World Without Us, reprises his role to help us think more about where the demographic math is leading us. Informative chapters give us an inside look into the realities within a number of individual countries. It makes for sobering reading, considering he barely acknowledges the factors of climate change and increasing resource use as people around the world raise their consumption levels.

“Whether we accept it or not, this will likely be the century that determines what the optimal human population is for our planet. It will come about in one of two ways:
Either we decide to manage our own numbers, to avoid a collision of every line on civilization's graph - or nature will do it for us, in the form of famines, thirst, climate chaos, crashing ecosystems, opportunistic disease, and wars over dwindling resources that finally cut us down to size.”
“In the days when money was backed by its face value in silver or gold, there were limits to how much wealth could flow around the world. Today, it's virtual money that the bank lends into existence on a computer screen. "And unless the economy continually expands, there is no new flow of money to pay back that money, plus interest." . . . "As it stands now, if banks start loaning money more slowly than they collect debts, the quantity of money in the economy goes down, and it's impossible to pay back debts. So we get defaults on houses . . . our economy plunges into misery and unemployment. Under our current monetary system, the only alternative to that is endless growth. So one absolute thing we have to change is the whole nature of the monetary system. . . . we deny banks the right to create money." . . . There's a challenge with that solution, he admits. "You're trying to take the right to create wealth away from some of the wealthiest people on the planet.” 5 likes
