In "A Short History of Nearly Everything," Bill Bryson explores the vast time scales of nature and the universe. One striking idea he presents is that it can take up to ten million years to cleanse an ocean. This highlights the slow, yet remarkably efficient processes of environmental recovery, illustrating the natural world's resilience over extended periods. Bryson emphasizes that while the timescales may seem daunting, the eventual results are both fascinating and positive.

This reflection serves as a reminder of the patience required to understand complex systems in nature. Bryson's writing encourages readers to appreciate the intricate workings of the earth, suggesting that while immediate results are often desired, true progress can unfold over millennia. The efficiency of nature’s processes stands in stark contrast to human urgency, inviting us to adopt a longer perspective on our relationship with the environment.
