Furthermore, modern people may lack ecological and environmental knowledge. Or they may know that natural resources are limited and that biodiversity is important, but be unable to refuse materialistic temptations, lack the time to recycle, and be powerless to refuse their children's requests for the fashionable pet of the moment. More knowledge does not necessarily help in easing environmental deterioration.
再說，現代人或許擁有不少生態環保知識──環境資源有限、生物多樣性，然而若在實際生活中，仍無法拒絕物質誘惑、無暇做資源回收、或經不起子女豢養流行寵物的要求......，再豐富的知識並無助於減緩生態環境的惡化。
