In 2022, human activities emitted over 40 billion metric tons of carbon dioxide (CO2) into the atmosphere, primarily from burning fossil fuels. A single metric ton of CO2 occupies a 27’ x 27’ x 27’ cube, equivalent to the weight of a great white shark or 400 bricks. The average American generates 15 tons annually, enough to fill over three Olympic-sized swimming pools. Everyday activities like driving (4.6 tons per year for a typical car) and air travel (1 ton per 3,000-mile round-trip flight) contribute significantly, alongside food production (2 tons per person annually). Large-scale processes, such as electricity generation and steel manufacturing (nearly 2 tons of CO2 per ton of steel), dominate emissions. Switching to electric vehicles can reduce emissions to 22% of a gas car’s output. Globally, 40 billion tons of CO2 would cover Alaska, Texas, and California to a depth of 27 feet, underscoring the scale of emissions.
