D: is incorrect because it says use technology, and the passage suggests that under no circumstance (even if stringent restrictions are placed on technology to balance the use of it) is technology to be used as it relates to the environment? (line 57-58).
I see why the correct answer is E. E, "setting aside land to be maintained and protected from ext ration of natural resources" is directly supported by the notion that environmental influence is taboo, technology should be distant from environment, and wilderness is adored (last paragraph).
