Some time ago, I made a public statement about an invisible threat infiltrating our bodies, our air, our water, and even our minds. I am referring to micro- and nanoplastics.
We, the volunteers of ALLATRA, sounded the alarm about this threat two decades ago. At the time, few were willing to listen. Today, science—including some of those who did hear us back then—has confirmed the warnings we issued: nanoplastic does not merely pollute. It exacerbates diseases and disrupts food chains. New research reveals that this threat is far more serious than we initially imagined, and it is now reshaping everything—from the climate to microbial ecosystems, from human health to the future of civilization itself.
We are not standing at the edge of the abyss—we are already in free fall. Today, I will speak about how we squandered the window of opportunity for simple solutions and how political barriers are now obstructing new ones. I will share what science has discovered in the intervening years and examine whether we, as a global community, can still avert this threat.
To grasp how deeply we are entangled in this unfolding catastrophe, let us first understand what micro- and nanoplastics are—and how they became the enemy of our own making.
Since the onset of mass plastic production in the 1950s, the world has manufactured more than 9 billion tons of plastic products. Of that amount, approximately 5 billion tons have ended up in landfills. About a quarter of a billion tons have reached a nanoplastic state in our atmosphere due to the incineration of 1 billion tons. Up to an additional 2.5 billion tons were improperly disposed of—meaning they have already entered our biosphere.
In other words, the vast majority of all plastic ever produced has not disappeared. It has simply changed form. And now, it’s in the water, in the soil, in our food, and inside our bodies.
Each year, more than 400 million tons of plastic waste are generated globally. Every minute, the equivalent of one full garbage truck’s worth of plastic is dumped into the world’s oceans. And with each passing year, this flow continues to accelerate. Estimates indicate that by 2040, if current trends persist, between 23 and 53 million tons of plastic will be entering aquatic ecosystems annually. By 2050, the total mass of plastic in the oceans may reach 12 billion tons—roughly equal to the weight of all the fish in all the oceans on Earth.
As I’ve already noted, plastic does not simply disappear. Under the influence of sunlight, waves, sea salt, and mechanical friction, it breaks down into microparticles (less than 5 millimeters) and nanoparticles (less than 1,000 nanometers—a thousandth the width of a human hair). This disintegration does not render it harmless. On the contrary, it transforms plastic into a nanomaterial that is virtually undetectable but easily penetrates living organisms.
It is crucial to understand that the primary reservoir of plastic—and therefore of micro- and nanoplastics—is the ocean. The ocean is the largest organ of our planet. It regulates the climate, produces oxygen, and sustains life. Just consider this: the ocean is the most vast and vital part of our world. And it is precisely this essential organ that has been inundated by one of the most inconspicuous yet most destructive enemies—nanoplastic.
We have contaminated the planet’s life-sustaining organ with an invisible toxin. Up to 350 trillion particles are in the ocean’s surface layer alone. Yet biologists acknowledge that 90 percent of nanoplastics are so small that our instruments cannot detect them.
