Oh, I see. Some bending is like that. Firebending, mostly. But bending has other uses too -- there was this one time we were in the Earth Kingdom? And this village was in danger of being wiped out by a volcano! So Sokka, Aang and I organized the villagers to fight it. Some of them were earthbenders and they dug deep trenches around the village to hold the lava. But in the end, Aang had to airbend the flow of the lava back because there was just too much.
