Bricks are everywhere, but they're also one of the biggest contributors to CO2 emissions. A company called Biomason has decided to take a different approach - using bacteria to grow useable building materials.
This means that companies don't have to create bricks at super high temperatures anymore - saving the planet a whole lot of emissions in the meantime.
Just pop this in with concrete that repairs itself and we've got a whole new way to build stuff!
