Pollution. A gas swimming in the air ready to strike at any time. They tried to stop it, but pollution was unstoppable. They had created a monster that was likely to never go away. It destroyed the oceans and plants, taking away the green from them. Turning it into a brown. Although it destroyed their world it did it slowly like a graceful dancer, creeping up behind them destroying one thing at a time. Some people knew about the danger. They wanted to stop it. End it, why they couldn’t do it was unknown. The rest of them didn’t care.
