The “second warning” for the future of our planet, the Apocalypse in sight?

25 years after a first warning of a majority of Nobel laureates, more than 15,000 scientists from 184 countries launch, in a statement, a second warning against the very high risks of destabilization of the Earth for lack of humanity to preserve the environment and ecosystems.

In 1992, the NGO “Union of Concerned Scientists” with more than 1,700 co-signatories, had already issued “The warning of scientists of the world to humanity” in which they argued that the impact of human activities on the nature would certainly lead to “great human suffering” and “mutilate our planet irreparably”.

Twenty-five years later, these scientists revisit the initial warning in a platform they call a “second warning”.

The Apocalypse in view?

Availability of drinking water, deforestation, declining numbers of mammals, greenhouse gas emissions: all these lights are in the red and responses since 1992 are disappointing, with the exception of international measures taken to stabilize the layer of ozone in the stratosphere, conclude the scientists whose appeal appears in the journal BioScience.

In this paper, we have studied the evolution of the situation over the last two decades and evaluated human responses by analyzing existing official data,” says Thomas Newsom, a professor at Deakin University in Australia, co-author of the statement. .

For a quarter of a century, the quantity of drinking water available on Earth per capita has decreased by 26% and the number of dead zones in the oceans has increased by 75%, say the researchers.

The call also gives the example of the loss of nearly 120.4 million hectares of forests converted for the most part to agricultural land and a significant increase in carbon dioxide (CO2) emissions and average temperatures of the planet. .

The researchers also point to the 35% increase in the world’s population and a 29% reduction in the number of mammals, reptiles, amphibians, birds and fish.

Among the measures advocated, the authors of the call suggest the creation of more terrestrial and marine nature reserves and stronger anti-poaching laws and stricter restrictions on trade in wildlife products.

To curb population growth in developing countries, they advocate greater generalization of family planning and women’s education programs.
