Opinion of the Court
caused him injury, and that a judgment preventing or requiring the action will redress it. When, however, as in this case, a plaintiff's asserted injury arises from the government's allegedly unlawful regulation (or lack of regulation) of someone else, much more is needed. In that circumstance, causation and redressability ordinarily hinge on the response of the regulated (or regulable) third party to the government action or inaction—and perhaps on the response of others as well. The existence of one or more of the essential elements of standing "depends on the unfettered choices made by independent actors not before the courts and whose exercise of broad and legitimate discretion the courts cannot presume either to control or to predict," ASARCO Inc. v. Kadish, 490 U. S. 605, 615 (1989) (opinion of Kennedy, J.); see also Simon, supra, at 41-42; and it becomes the burden of the plaintiff to adduce facts showing that those choices have been or will be made in such manner as to produce causation and permit redressability of injury. E. g., Warth, supra, at 505. Thus, when the plaintiff is not himself the object of the government action or inaction he challenges, standing is not precluded, but it is ordinarily "substantially more difficult" to establish. Allen, supra, at 758; Simon, supra, at 44-45; Warth, supra, at 505.

We think the Court of Appeals failed to apply the foregoing principles in denying the Secretary's motion for summary judgment. Respondents had not made the requisite demonstration of (at least) injury and redressability.

Respondents' claim to injury is that the lack of consultation with respect to certain funded activities abroad "increas[es] the rate of extinction of endangered and threatened species." Complaint ¶ 5, App. 13. Of course, the desire to use or observe an animal species, even for purely esthetic purposes, is undeniably a cognizable interest for purpose of
