english: And it's good for the planet, too: the trees absorbed carbon when they were growing up, and they gave off oxygen, and now that carbon is trapped inside the walls and it's not being released into the atmosphere.
non_english: A je dobrý aj pre planétu. Stromy pri raste viažu uhlík a produkujú kyslík. Uhlík sa takto zachytí v stenách budovy a nevypúšťa sa do atmosféry.
