How long does it take earth to become more dirty?

The rate at which Earth becomes "dirty" can vary significantly depending on human activities, pollution levels, and environmental management practices. Urbanization, industrial processes, and waste generation can increase pollution rapidly, while conservation efforts and technology can mitigate these effects. In general, without intervention, pollution and environmental degradation can accumulate over weeks, months, or years, depending on the specific context and location. Overall, the timeline for Earth becoming "dirtier" is complex and influenced by numerous factors.
