The phrase "unlike the buried pirates' gold in Treasure Island" reflects the tone of the author's conclusion by emphasizing the idea that the seeds have monetary value. However, this is not the primary message conveyed in the context. The primary contrast is that, while pirates' gold symbolizes a treasure that is hoarded for personal wealth, the seeds represent a wealth that is essential for the future survival of humanity and the planet.
The best answer, considering the overall message and intent, is:
- It emphasizes the author's reverence for the seeds.
This choice captures the idea that the seeds hold intrinsic value for sustaining life, unlike the gold which is a mere symbol of wealth and greed.
