In the 1990, s, for example, the woodcutters in the Western United States were challenged legally in their attempt to cut trees for timber in the Cascade Mountains.

But the developing countries may be impoverished (使窮困 ), with populations growing so rapidly that using the land is a means to temporarily avoid worsening poverty and starvation. Many of the changes to Earth that concern scientists have the potential to rob the pla of its biological richness. Global warming, for example, could wipe out species unable to quickly adapt to changing climates. Clearly, protecting Earth’s biological diversity is a plex problem. But solutions to humanity’s current problems will e only through coordinated international efforts to control human population, stabilize the position of the atmosphere, and preserve intact Earth’s plex web of life. 62.
