Why the world's most common building material is heating the planet
In short: Concrete is everywhere, from our sidewalks to skyscrapers, but its production has a significant impact on global temperatures. This video explores why this essential material is problematic and how scientists are developing sustainable alternatives.
Concrete is a fundamental component of modern infrastructure, used in everything from roads and bridges to skyscrapers. The scale of its use is immense, with an estimated three tons of concrete existing for every person on Earth.
Beyond its ubiquity, the production of concrete has played a surprisingly large role in the rise of global temperatures over the last century. Scientists are now investigating ways to engineer a cleaner, more sustainable version of this material to mitigate its environmental impact.
