 That's right. Yeah. So in the global carbon cycle, an enormous amount of Earth's carbon is stored in limestone. Wow. So this is, it's like you hear about the tundra, you know, the tundra that's defrosting in the Arctic and that's a carbon sink. And obviously when it defrosts, it releases carbon. So this is a deliberate process to make cement, but it's essentially just releasing all this carbon, which is a huge problem. Yeah.
