Elizabeth Isaacs said this quote

Seeing that humans in modern cultures were destroying their environment for the sake of self-indulgence, the Dokkalfar focused their attention on poorer nations, whose terrain still flourished. A century of ethnic cleansing, deforestation, and war assured the land weakened and humans stayed in abject poverty. The result was a perfect contrast. In certain parts of the world, millions of children died of starvation and disease while other countries held excesses and riches never before seen. Earth became a place of greedy extremes. Societies lost the ability to relate to one another, choosing instead to focus on their own. No one noticed the one common theme every culture held. The world itself was dying.
