The world is not getting any bigger but the human population continues to grow, consuming more and more resources and altering the very environment we rely on.

In 2020, the amount of human-made mass, or anthropogenic mass, exceeded for the first time the dry weight (except for water and fluids) of all life on Earth, including humans, animals, plants, fungi, and even microorganisms.

In this infographic based on a study published in Nature, we break down the composition of all human-made materials and the rate of their production.

A Man-made Planet

Anthropogenic mass is defined as the mass embedded in inanimate solid objects made by humans that have not been demolished or taken out of service—which is separately defined as anthropogenic mass waste.

Over the past century or so, human-made mass has increased rapidly, doubling approximately every 20 years. The collective mass of these materials has gone from 3% of the world’s biomass in 1900 to being on par with it today.

While we often overlook the presence of raw materials, they are what make the modern economy possible. To build roads, houses, buildings, printer paper, coffee mugs, computers, and all other human-made things, it requires billions of tons of fossil fuels, metals and minerals, wood, and agricultural products.

Human-Made Mass

Every year, we extract almost 90 billion tons of raw materials from the Earth. A single smartphone, for example, can carry roughly 80% of the stable elements on the periodic table.

The rate of accumulation for anthropogenic mass has now reached 30 gigatons (Gt)—equivalent to 30 billion metric tons—per year, based on the average for the past five years. This corresponds to each person on the globe producing more than his or her body weight in anthropogenic mass every week.

At the top of the list is concrete. Used for building and infrastructure, concrete is the second most used substance in the world, after water.

Human-Made MassDescription1900 (mass/Gt)1940 (mass/Gt)1980 (mass/Gt)2020 (mass/Gt)
ConcreteUsed for building and infrastructure, including cement, gravel and sand21086549
AggregatesGravel and sand, mainly used as bedding for roads and buildings1730135386
BricksMostly composed of clay and used for constructions11162892
AsphaltBitumen, gravel and sand, used mainly for road construction/pavement 012265
MetalsMostly iron/steel, aluminum and copper131339
OtherSolid wood products, paper/paperboard, container and flat glass and plastic461123

Bricks and aggregates like gravel and sand also represent a big part of human-made mass.

Although small compared to other materials in our list, the mass of plastic we’ve made is greater than the overall mass of all terrestrial and marine animals combined.

Human-Made Mass Plastic

As the rate of growth of human-made mass continues to accelerate, it could become triple the total amount of global living biomass by 2040.

Can We Work It Out?

While the mass of humans is only about 0.01% of all biomass, our impact is like no other form of life on Earth. We are one of the few species that can alter the environment to the point of affecting all life.

At the current pace, the reserves of some materials like fossil fuels and minerals could run out in less than 100 years. As a result, prospectors are widening their search as they seek fresh sources of raw materials, exploring places like the Arctic, the deep sea, and even asteroids.

As the world population continues to increase, so does the pressure on the natural environment. It is an unavoidable fact that consumption will increase, but in an era of net-zero policies and carbon credits, accounting for the human impact on the environment will be more important than ever.

Synthetic Biology: The $3.6 Trillion Science Changing Life as We Know It

The field of synthetic biology could solve problems in a wide range of industries, from medicine to agriculture—here’s how.

How Synthetic Biology Could Change Life as we Know it

Synthetic biology (synbio) is a field of science that redesigns organisms in an effort to enhance and support human life. According to one projection, this rapidly growing field of science is expected to reach $28.8 billion in global revenue by 2026.

Although it has the potential to transform many aspects of society, things could go horribly wrong if synbio is used for malicious or unethical reasons. This infographic explores the opportunities and potential risks that this budding field of science has to offer.

What is Synthetic Biology?

We’ve covered the basics of synbio in previous work, but as a refresher, here’s a quick explanation of what synbio is and how it works.

Synbio is an area of scientific research that involves editing and redesigning different biological components and systems in various organisms.

It’s like genetic engineering but done at a more granular level—while genetic engineering transfers ready-made genetic material between organisms, synbio can build new genetic material from scratch.

The Opportunities of Synbio

This field of science has a plethora of real-world applications that could transform our everyday lives. A study by McKinsey found over 400 potential uses for synbio, which were broken down into four main categories:

  • Human health and performance
  • Agriculture and food
  • Consumer products and services
  • Materials and energy production

If those potential uses become reality in the coming years, they could have a direct economic impact of up to $3.6 trillion per year by 2030-2040.

1. Human Health and Performance

The medical and health sector is predicted to be significantly influenced by synbio, with an economic impact of up to $1.3 trillion each year by 2030-2040.

Synbio has a wide range of medical applications. For instance, it can be used to manipulate biological pathways in yeast to produce an anti-malaria treatment.

It could also enhance gene therapy. Using synbio techniques, the British biotech company Touchlight Genetics is working on a way to build synthetic DNA without the use of bacteria, which would be a game-changer for the field of gene therapy.

2. Agriculture and Food

Synbio has the potential to make a big splash in the agricultural sector as well—up to $1.2 trillion per year by as early as 2030.

One example of this is synbio’s role in cellular agriculture, which is when meat is created from cells directly. The cost of creating lab-grown meat has decreased significantly in recent years, and because of this, various startups around the world are beginning to develop a variety of cell-based meat products.

3. Consumer Products and Services

Using synthetic biology, products could be tailored to suit an individual’s unique needs. This would be useful in fields such as genetic ancestry testing, gene therapy, and age-related skin procedures.

By 2030-2040, synthetic biology could have an economic impact on consumer products and services to the tune of up to $800 billion per year.

4. Materials and Energy Production

Synbio could also be used to boost efficiency in clean energy and biofuel production. For instance, microalgae are currently being “reprogrammed” to produce clean energy in an economically feasible way.

This, along with other material and energy improvements through synbio methods, could have a direct economic impact of up to $300 billion each year.

The Potential Risks of Synbio

While the potential economic and societal benefits of synthetic biology are vast, there are a number of risks to be aware of as well:

  • Unintended biological consequences: Making tweaks to any biological system can have ripple effects across entire ecosystems or species. When any sort of lifeform is manipulated, things don’t always go according to plan.
  • Moral issues: How far we’re comfortable going with synbio depends on our values. Certain synbio applications, such as embryo editing, are controversial. If these types of applications become mainstream, they could have massive societal implications, with the potential to increase polarization within communities.
  • Unequal access: Innovation and progress in synbio is happening faster in wealthier countries than it is in developing ones. If this trend continues, access to these types of technology may not be equal worldwide. We’ve already witnessed this type of access gap during the rollout of COVID-19 vaccines, where a majority of vaccines have been administered in rich countries.
  • Bioweaponry: Synbio could be used to recreate viruses, or manipulate bacteria to make it more dangerous, if used with ill intent.

According to a group of scientists at the University of Edinburgh, communication between the public, synthetic biologists, and political decision-makers is crucial so that these societal and environmental risks can be mitigated.

Balancing Risk and Reward

Despite the risks involved, innovation in synbio is happening at a rapid pace.

By 2030, most people will have likely eaten, worn, or been treated by a product created by synthetic biology, according to synthetic biologist Christopher A. Voigt.

Our choices today will dictate the future of synbio, and how we navigate through this space will have a massive impact on our future—for better, or for worse.

How Far Are We From Phasing Out Coal?

At the COP26 conference last year, 40 nations agreed to phase coal out of their energy mixes.

Despite this, in 2021, coal-fired electricity generation reached all-time highs globally, showing that eliminating coal from the energy mix will not be a simple task.

This infographic shows the aggressive phase-out of coal power that would be required in order to reach net zero goals by 2050, based on an analysis by Ember that uses data provided by the International Energy Agency (IEA).

Low-Cost Comes at a High Environmental Cost

Coal-powered electricity generation rose by 9.0% in 2021 to 10,042 Terawatt-hours (TWh), marking the biggest percentage rise since 1985.

The main reason is cost. Coal is the world’s most affordable energy fuel. Unfortunately, low-cost energy comes at a high cost for the environment, with coal being the largest source of energy-related CO2 emissions.

China has the highest coal consumption, making up 54% of the world’s coal electricity generation. The country’s consumption jumped 12% between 2010 and 2020, despite coal making up a lower percentage of the country’s energy mix in relative terms.

Top Consumers2020 Consumption (Exajoules) Share of global consumption
China 🇨🇳82.354.3%
India 🇮🇳17.511.6%
United States 🇺🇸9.26.1%
Japan 🇯🇵4.63.0%
South Africa 🇿🇦3.52.3%
Russia 🇷🇺3.32.2%
Indonesia 🇮🇩3.32.2%
South Korea 🇰🇷3.02.0%
Vietnam 🇻🇳2.11.4%
Germany 🇩🇪1.81.2%

Together, China and India account for 66% of global coal consumption and emit about 35% of the world’s greenhouse gasses (GHG). If you add the United States to the mix, this goes up to 72% of coal consumption and 49% of GHGs.

How Urgent is to Phase Out Coal?

According to the United Nations, emissions from current and planned fossil energy infrastructure are already more than twice the amount that would push the planet over 1.5°C of global heating, a level that scientists say could bring more intense heat, fire, storms, flooding, and drought than the present 1.2°C.

Apart from being the largest source of CO2 emissions, coal combustion is also a major threat to public health because of the fine particulate matter released into the air.

As just one example of this impact, a recent study from Harvard University estimates air pollution from fossil fuel combustion is responsible for 1 in 5 deaths globally.

The Move to Renewables

Coal-powered electricity generation must fall by 13% every year until 2030 to achieve the Paris Agreement’s goals of keeping global heating to only 1.5 degrees.

To reach the mark, countries would need to speed up the shift from their current carbon-intensive pathways to renewable energy sources like wind and solar.

How fast the transition away from coal will be achieved depends on a complicated balance between carbon emissions cuts and maintaining economic growth, the latter of which is still largely dependent on coal power.
