Introduction

C'est un roman serein: la disparition des humains n'est pas un drame et la nature continue de plus belle.
L'histoire générale des humains depuis leur apparition est une suite de réussites confirmées par l'expansion de leurs représentants. Le roman en est la déconstruction. 
On fera décroître plus vite les peuples qui ont cru le plus. Et les humains vivront cette décrue comme ils vivent leur crue actuelle, sans s'en apercevoir. 
Cette décroissance  dure cent ans car un certain nombre des enfants nés le 31 décembre 2017 avant minuit vont vivre 100 ans.

Humans Change the World - http://humanorigins.si.edu/human-characteristics/humans-change-world

200,000 Years Ago

Modern Humans Evolve in Africa

During a time of dramatic climate change, modern humans (Homo sapiens) evolved in Africa. Like early humans, modern humans gathered and hunted food. They evolved behaviors that helped them respond to the challenges of survival.
The first modern humans shared the planet with at least three species of early humans. Over time, as modern humans spread around the world, the other three species became extinct. We became the sole survivors in thehuman family tree.

12,000 Years Ago
The Turning Point
Eventually, humans found they could control the growth and breeding of certain plants and animals. This discovery led to farming and herding animals, activities that transformed Earth’s natural landscapes—first locally, then globally.
As humans invested more time in producing food, they settled down. Villages became towns, and towns became cities. With more food available, the human population began to increase dramatically.

Humans Change the World: Today

Modern humans have spread to every continent and grown to huge numbers. Producing our own food, rather than tracking it down daily, has freed us to enrich our lives in many ways—to become artists, inventors, scientists, politicians, and more.
We have altered the world in ways that benefit us greatly. But this transformation has unintended consequences for other species as well as for ourselves, creating new survival challenges.
By 1995, at least 83% of Earth’s land surface had been directly affected by humans.
In 2004, the International Union for Conservation of Nature (IUCN) reported that current bird, mammal, and amphibian extinction rates were at least 48 times greater than natural extinction rates—possibly 1,024 times higher.
As of 2005, humans had built so many dams that nearly six times as much water was held in storage as flowed freely in rivers.

Benefits and Costs of Our Success

Benefits
By settling down and producing our own food, we created:
●enough food to feed billions of people and respond to catastrophes;
●buildings that protect us from extreme weather;
●technologies that enable us to extend our lives, communicate worldwide, and venture into space;
●time to think, create, play, socialize, and much more.

Costs
By settling down and producing our own food, we created:
●piles of waste that form natural breeding grounds for contagious diseases;
●large concentrations of people, enabling diseases to spread and become epidemics;
●domesticated landscapes that displace wild habitats;
●loss of wild species that depend on natural habitats.

Great Moments in Food Technology

1928 - Sliced bread
1791 - Artificial teeth
63 BCE - Water-powered grist mill
500 BCE - Iron plow
9500 BCE - Grain storehouse

Changing the World:

Animal Domestication

FACT: From 1961 to 2004, the population of cattle, pigs, sheep, and goats increased from 2.7 to 4.1 billion. The number of domesticated fowl grew from 3 to 16 billion.
FACT: Of the estimated 15,000 species of mammals and birds, only about 30–40 have been used for food.
FACT: Fewer than 14 species of animals account for 90% of global livestock production today.

Changing the World:

Agriculture

FACT: About a quarter of Earth’s surface is used to grow crops.
FACT: Fewer than 20 plant species produce most of the world’s food.
FACT: Most of the world’s population is dependent on 4 main crops: wheat, corn, rice, and potatoes.

Changing the World:

Growing Numbers of People

FACT: Between 1959 and 1999, just 40 years, the human population doubled from 3 billion to 6 billion people.
FACT: Today the population continues to grow by over 90 million people a year.
FACT: By 2042, the world population may reach 9 billion, an increase of 50% in 43 years.

Changing the World:  

Unintended Consequences

FACT: A cholera pandemic that began in 1961 is still ongoing in Asia, Africa, and the Americas. The number of cases reported in 2006 was 79% more than in 2005.
FACT: Every year between 3 and 5 million people get “the flu,” and between 250,000 and 500,000 people die from it.
FACT: A child dies of malaria every 30 seconds. About 40% of the world’s population is at risk of malaria.
FACT: Every second someone in the world is infected with tuberculosis. One-third of the world’s population is infected.
