The extent of humanity's influence on the planet has become increasingly clear in recent years. From the alarming accumulation of plastic waste in our oceans to the sprawling growth of urban areas, the size of our impact is undeniable.

The concept of the "technosphere" aims to reveal the immense scale of our collective impact. The concept was by US geologist Peter Haff in 2013, but paleobiologist Jan Zalasiewicz has since popularized the term through his work. The technosphere encompasses the generated by human activities, as well as the associated energy consumption.

Since the agricultural revolution some 12,000 years ago (when we started building cities and accumulating goods), human enterprise has steadily grown. However, our impact has surged dramatically over the past couple of centuries. This surge has since transformed into , particularly since 1950.

The technosphere is indicative of how humans are increasingly emerging as a global force on par with the natural systems that shape the world. The transformation that is needed to reduce our impact is therefore equally large. And yet, despite growing awareness, there has been a to address humanity's impact on the planet.

To comprehend the sheer magnitude of the technosphere, it is best visualized. So here are four graphs that capture how our collective addiction to "stuff" is progressively clogging up planet Earth.

1. Weighing the technosphere

In 2020, a group of Israeli academics : the combined mass of all materials currently utilized by humanity had surpassed the total mass of all living organisms on Earth.

According to their findings, the collective weight of all life on Earth (the biosphere)—ranging from microbes in the soil, to trees and animals on land—stands at 1.12 trillion tons. While the mass of materials actively used by humans, including concrete, plastic and asphalt, weighed in at 1.15 trillion tons.

The technosphere weighs more than all life on Earth (trillion tons):

This graph offers a glimpse into the immense size of humanity's footprint. But it likely only scratches the surface.

When accounting for the associated byproducts of the materials used by humans, including waste, plowed soil and greenhouse gases, the geologist and paleontologist, Jan Zalasiewicz, calculated that the technosphere expands to a staggering . This would include a mass of industrially emitted carbon dioxide equivalent to 150,000 Egyptian Pyramids.

2. Changing the Earth

Remarkably, human activity now dwarfs natural processes in changing the surface of our planet. The total global sediment load (erosion) that is transported naturally each year, primarily carried by rivers flowing into ocean basins, is estimated to be around on average. However, this natural process has been overshadowed by the mass of material moved through human action like construction and mining activities.

In fact, the mass of material moved by humans and has since grown rapidly. In 2015 alone, humans moved approximately —more than ten times the natural sediment load.

Humans change the Earth's surface more than natural processes (billion tons):

3. Transporting 'stuff'

Our ability to transport fuel and products worldwide has facilitated the trends shown in the preceding graphs. Humans now transport these materials over increasingly vast distances.

Shipping continues to be the primary mechanism for moving materials around the globe. Since 1990, the amount of materials that are shipped around the world has increased —and is .

How shipping has grown since 1980 (million tons):

4. The growth of plastics

Plastic stands out as one of the main "wonder materials" of the modern world. Due to the sheer speed and scale of the growth in plastic manufacturing and use, plastic is perhaps the metric most representative of the technosphere.

The first forms of plastic emerged in the early 20th century. But its mass production began following the second world war, with an produced in 1950. However, the global production of plastic had increased to approximately 460 million tons by 2019.

This surge in plastic manufacturing is a pressing concern. Plastic pollution now causes many negative impacts on both and . Ocean plastics, for example, can degrade into smaller pieces and be ingested by marine animals.

Plastic manufacturing (million tons) has grown exponentially since 1950:

Humanity's escalating impact on planet Earth poses a significant threat to the health and security of people and societies worldwide. But understanding the size of our impact is only one part of the story.

Equally important is the nature, form and location of the different materials that constitute the technosphere. Only then can we understand humanity's true impact. For example, even the tiniest materials produced by humans, such as , can have significant and far-reaching consequences.

What is clear, though, is that our relentless pursuit of ever-increasing material output is overwhelming our planet.
