  So what is the character of entities as revealed technologically? Heidegger's claim is that the “revealing that holds sway throughout modern technology… [is]… a challenging… which puts to nature the unreasonable demand that it supply energy which can be extracted and stored as such” (Question Concerning Technology 320). The mode of revealing characteristic of modern technology understands phenomena in general—including the non-biological natural world, plants, animals, and indeed human beings—to be no more than what Heidegger calls standing-reserve, that is, resources to be exploited as means to ends. This analysis extends to regions of nature and sections of society that have not yet been harnessed positively as resources. Such unexploited elements (e.g., an unexplored jungle, this year's unemployed school leavers) exist technologically precisely as potential resources.
