How to Fix the Planet, the Easy Way

To avoid disastrous deterioration of Earth’s climate and biosphere, humanity has to reduce its demands on nature. Fewer births and a falling population is no quick fix, but compared with voluntary austerity, it has many more up-sides than down-sides. by Jon Austen Scientists are reporting that there is an existential threat to life on Earth. … Continue reading How to Fix the Planet, the Easy Way →

How environmental professionals acknowledge overpopulation – and then ignore it

We can have an environmentalism that ignores the fundamental causes of environmental problems, including lucrative careers treating overshoot’s many symptoms.

Delusional population projections lead us sleepwalking into catastrophe

Recent United Nations population projections paint a comforting picture of immanent population stabilization. But what if they are wrong? Global population growth does not appear to be slowing as quickly as UN demographers have predicted, making widespread famines and run-away climate change more likely in the coming decades. By Jane O’Sullivan The Elon Musks of … Continue reading Delusional population projections lead us sleepwalking into catastrophe →

Procreation and Consumption in the Real World

The cause of global environmental decline is clear: an immense and rapidly growing human economy. In response, environmentalists should advocate policies leading to fewer people and lower per capita consumption, not one instead of the other. Addressing both provides our best hope of creating sustainable societies and preserving Earth’s remaining biodiversity. by Philip Cafaro There … Continue reading Procreation and Consumption in the Real World →

Human population reduction is not a quick fix for environmental problems

Then again, neither is anything else. The long lag time between fertility reduction and population stabilization is a key reason we need to address excessive human numbers sooner rather than later. by Phil Cafaro There's an argument one often hears that goes like this: "sure, population is important. But we need to reduce our environmental … Continue reading Human population reduction is not a quick fix for environmental problems →

Walk the talk: the world needs more Gretas and fewer Leonardos

History was rewritten to delegitimize population concerns: we need to reassert the truth

In the old fable of the Emperor’s New Clothes, people denied the emperor’s nakedness because they wanted to be seen as smart. Today people deny overpopulation because they want to be seen as moral.

Two ways to argue for population’s importance

Here at TOP, we are often asked how we define overpopulation and whether it’s a helpful concept. Good questions!
