In 2024, humanity - as a whole - took a purposeful stride
towards engineering the collapse of modern civilisation.

As a science writer and a grandparent, Julian
Cribb is deeply concerned at the existential emergency facing humanity,
the mounting scientific evidence for it and the deficit of clear
thinking about how to overcome it. |
While
climate, politics, wars and celebrities vied for the headlines, the
hard indicators of human management of Planet Earth and our own future
all pointed south.
Here is the state of the main catastrophic risks for
2024, based on trusted information:
- Forest loss:
488 m ha tree cover lost since 2000. Current loss is around 25mha/ year
to all causes, including agriculture, development, wildfires and
climate.
- Water: 4.1 billion people experienced severe water scarcity for at least part of 2024. This is expected to worsen in 2025.
- Soil loss: 40% of the world’s topsoil is lost or degraded, damaging food and nutrition for 3 billion people.
- Fish: 38% of world capture fisheries are now rated unsustainable.
- War: the Doomsday Clock stands at 90 seconds to midnight, the highest threat level since WW2 and the 1980s.
- Climate:
2024 is the hottest year ever recorded at +1.54 degrees above
preindustrial levels. Humans emitted 41.6 bn tonnes of CO2 in 2024.
Atmospheric carbon levels were 425ppm in December and rising at record
rates.
- Pandemics:
Covid: 770m cases and 7m deaths since 2020 and still spreading. HIV:
88m cases and 44m deaths and still spreading. Emerging pandemic risks
include Avian Flu, Marburg, Zika and Nipah.
- Food scarcity:
Food prices remain high, globally. 770 million people face hunger and
343 million, acute food scarcity. Climate, soil loss, water scarcity and
eco-decline are major drivers.
- Extinction:
73% decline in global wildlife populations in past 50 years, driven by
habitat loss and degradation due to agriculture and development,
overharvesting and spread of toxic chemicals.
- Pollution: 14 million deaths (24%) are linked to a polluted environment, soil, water, food, homes and cities.
- Technology threats:
several advanced technologies pose catastrophic risks, driven by
industry competition and political manipulation. These include AI,
robotic killing machines, nanotechnology, cyber theft, gain-of-function
biotechnology and universal surveillance.
- Population:
The Earth’s human population reached 8.2 billion in 2024. It is
currently growing at 70m a year and is forecast to peak at 10.3bn in the
mid-2080s.
- Migration: world population movements hit a new peak of over 400m in 2024, comprising 281 million voluntary migrants and 123 million forced migrants. On average 4% of the human population is on the move each year.
- Misinformation:
misinformation, anti-science and lies reached a new peak in 2024,
affecting national elections, the climate debate, conflict, social
media, mainstream media, advertising, public trust in medicine, and
conspiracies.
This brief summary of current threat levels of the main catastrophic risks menacing the human population overall show that the problem is far more complex that many people seem to think.
It is not just about climate. Or even the threat of nuclear war. It is the whole railway-smash of multiple catastrophes coming together at one time.
If you scrape away the politics, the propaganda and other forms of misleading information, you are left with an undeniable, scientifically-evidenced truth: the root of the problem lies in human overpopulation, overconsumption and over-pollution.
Humanity is now exploding past the liveable boundaries of Planet Earth, as the Stockholm Resilience Centre has been warning us, for fifteen years now.
Any farmer can tell you what happens if you try to graze 1000
cattle in a field large enough to support only 250. They die horribly,
as feed and water run out. There are countless examples of this in both nature and human affairs.
According
to a growing number of scientists, humans have currently overpopulated
the planet by a factor of three or four – and the decline in natural
resources, climate crisis, food crisis, pandemics, spreading poisons,
extinction rates, soaring migration and resulting social pressures are
the direct and self-evident consequences.
No country on earth has a
solution to this problem, for the simple reason that countries and
their blind self-interest, are the main cause of it. By uniting
ourselves into ever-larger territorial units and then vying over the
Earth’s dwindling resources we are perfecting an engine for our own
extermination – an engine decorated with flags, anthems, symbols,
‘national pride’ and other chauvinistic rubbish.
It is a brutal
truth of modern politics that countries are never going to agree with
one another to save humanity, or how to do it, before it is far too late
to do so. Indeed, many now seem bent on installing crude, autocratic
regimes that will accelerate their ruin. 2024 marked an ominous
milestone in that grim regression.
If humans are to have any
chance of avoiding the collapse that is now so powerfully indicated,
then it is only by the individual citizens of the Earth, led by women,
joining hands to do so – despite the corruption of rulers, the ignorance
of oligarchs and the self-interest of corporations, ethnicities and
beliefs.
If we humans are to survive, on a planet fit to be
inhabited by our grandchildren, then first of all we must agree to
survive. There is no other choice.
An excellent starting
point would be to forge a world agreement to survive, which pledges us
to addressing each of the catastrophic threats we face. That is what the
Earth System Treaty proposes.
Let
2025 be the Year of the Treaty – first first-ever democratic agreement
by the people of the Earth to build a brighter, safer future.
