The quote highlights the idea that efforts to recreate a natural environment from the past, such as bringing extinct creatures back to life, are inherently flawed. The speaker asserts that such endeavors are impossible, indicating that the complexities of nature are far beyond human manipulation. Just as one can confidently determine tax obligations without calculation, the speaker is certain that duplicating the intricate balance of nature is unfeasible.

This perspective suggests a recognition of the limitations of science and the profound understanding of ecological systems. While the ambition to create isolated worlds with extinct species is intriguing, it ultimately underestimates the complexity and interconnectedness of natural environments. The notion of artificially reproducing such systems is critiqued, emphasizing that nature cannot simply be replicated like a formula or a calculation.
