Which statement is representative of an environmental wisdom worldview? 

A)  More money should be directed to research on controlling the environment. 
B)  Continuous rapid economic growth will improve environmental conditions. 
C)  Human beings are the most important life forms on Earth. 
D)  Energy and materials efficiency must continually be improved.

The statement "Energy and materials efficiency must continually be improved" is representative of an environmental wisdom worldview. This worldview emphasizes the importance of sustainable resource use and recognizes the interdependence of humans and the environment. Option A is not representative because it assumes control over the environment rather than working in harmony with it. Option B is not representative because it assumes that economic growth and environmental conditions are positively correlated, which is not always the case. Option C is not representative because it prioritizes human beings over other species and ecosystems, which goes against principles of environmental sustainability.
