THE FUNGUS AMONG US:

Mycelium bricks are made out of mushrooms, specifically microscopic fungi fibers that can be found in agricultural waste, like straw or chaff.

Mycelium is the rootlike material at the base of a mushroom. It can grow to fill different spaces or shapes when it is combined with organic material. It is also extremely strong and water-resistant -- one study even suggested that mycelium bricks are bulletproof.

The building and construction sector was responsible for around 37% of the world's energy and process-related carbon dioxide emissions in 2021, which had increased since before the pandemic. This means that the industry is far from on track to meet its goals to decarbonize by 2050 and must dramatically reduce its polluting practices. 

One area where there is room for improvement is in its production of building materials. The cement industry alone accounts for at least 8% of the world's carbon dioxide emissions.
