Question

Read the following excerpt from "The City Without Us" by Alan Weisman:
Yet with each new acid-free rainfall, trees that still endure
will have fewer contaminants to resist as chemicals are
gradually flushed from the system. Over centuries,
vegetation will take up decreasing levels of heavy metals,
and will recycle, redeposit, and dilute them further. As
plants die, decay, and lay down more soil cover, the
industrial toxins will be buried deeper, and each
succeeding crop of native seedlings will do better.
