The sentence talks about the potential consequences of pollution on the availability of pure air in the future. The word "vanish" fits best here as it means "disappear" or "cease to exist," which aligns with the context of pure air disappearing due to pollution. Coagulate refers to the process of a substance, especially a liquid, becoming thick or solid, which doesn't fit the meaning needed here.
