PARIS, December 19 (IPS) - Today, society is rightly concerned about the rising prevalence of autism among children worldwide; affecting up to 1% of children, it has a profound impact on families. Neuroinflammation and environmental origins are increasingly implicated. But what causes them?

Let us take a broader view. Depression among adolescents is widespread, without it being possible to clearly separate social from neurological causes. Even in China, scientists have demonstrated a link between pollution, asthma, and depression among young people.

Genetic factors, while not excluded, cannot explain everything, as they do not change rapidly enough to account for such a swift increase across the population. Likewise, when we include neurodegenerative diseases among older people, and even among younger adults, the number of people affected becomes staggering. Finally, environmentally linked cancers affect at least one in three people worldwide.

All these diseases and conditions are chronic and slow developing. Medicine primarily alleviates their symptoms, while their causes lead to extremely serious consequences for society. If we then look at the biosphere as a whole, species extinction and abnormalities, alongside climate disruption, we gain certainty about the role of anthropogenic effects in these problems. This is neither the result of individual ill will nor bad luck, but rather the rotten fruit of a system.

An increasing number of specialists believe that a paradigm shift is necessary to break free from this situation. Recently, forty-three of us from five continents co-signed an article in Environmental Sciences Europe, a high-impact scientific journal, detailing the malpractice surrounding the authorization of toxic substances, particularly pesticides and plasticizers.

The historical archives of Monsanto-Bayer have shown how doubt has been deliberately maintained through dishonest practices in order to keep society in ignorance, falsely believing that authorized products are properly assessed. These revelations, made possible through the U.S. justice system, led to convictions for fraud benefiting more than 100,000 cancer patients.

The issue is closely related when it comes to disabilities, yet these remain neglected. According to a recent French parliamentary report, 50,000 pupils are currently without appropriate support solutions, compared with 36,000 in 2024. Among them are many autistic children suffering from gastrointestinal microbiota disorders, one of the leading reasons for medical consultations. This highlights the devastation caused by ultra-processed food, which has harmful effects on food intolerances. We now understand how the nervous system surrounding the intestine, the “second brain,” connected to the primary one, malfunctions.

Let us already do, humbly, what we can where we are, much like Pierre Rabhi’s hummingbird parable, which seeks to extinguish a forest fire with the water carried in its beak: “At least I will have tried.” This is what the association LEX Les Enfants Extraordinaires does in Barjac, in the Gard region, France. It welcomes young people with disabilities who have no support solutions, offering them a social life alongside the village’s older residents. Organic gardening and cooking workshops are welcoming spaces, at least without adding pesticides and pollutants; work is done through short supply chains. Equine-assisted activities, animal-assisted therapy, and wheelchair repairs also allow participants to once again become givers of joy and creators of smiles.

Taken individually, these diseases are sometimes attributed to bad luck or to various social causes. But one inevitably thinks of epigenetic or transgenerational, therefore environmental, inheritance. We shudder at the effects of persistent, fossil-based pollutants, starting from the fetus and pregnancy, since we have shown that they cross the placenta, as do some of the world’s most widely used pesticides, such as Roundup, implicated in Monsanto-Bayer’s frauds. These substances accumulate in our environment, limited by the atmosphere; all forms of life are sensitive to and subjected to them.

We detect how pollutants embed themselves in all living tissues and are deliberately disseminated. They are laden with heavy metals, derived from carcinogenic and neurotoxic petroleum residues used in their manufacture. We have demonstrated that all endocrine disruptors are also neurotoxic through other cellular mechanisms, like sand gradually clogging and disrupting the brain and nervous system.

Solutions do exist. We can feed the world through agroecological agriculture, as specifically demonstrated by international reports from Olivier De Schutter. This requires raising fewer pigs, chickens, and cattle in intensive systems, as these practices saturate the ultra-processed food of wealthy countries with pollutants. Such intensive systems are unnecessary. Today, we maintain more suffering livestock than children worldwide.

Agroecological agriculture will regenerate ecosystems, fortunately highly resilient, through credible alternatives already implemented across the planet. Sadly, these are currently stifled by legislative gridlock generated by lobbying efforts designed to preserve the outdated, intensive post-war model. Outdated, because “growth” is a flawed concept, built on neglect and the deliberate omission of externalities. But we will get there.
