Despite the fact that Leave No Trace is a widely accepted conservationist ethic, there has been a good amount of criticism. Environmental historian James Morton Turner argued in 2002 that Leave No Trace focused attention of backpackers "largely on protecting wilderness as a recreational landscape" rather than tackling larger questions, such as "the modern economy, consumerism, and the environment". Turner also argues that this ethic omitted the calculus behind it, and the code itself, in his view, "helped ally the modern backpacker with the wilderness recreation industry" by encouraging backpackers to practice the Leave No Trace ethic while in the wilderness and to keep an eye out for the logo of this ethic in shopping malls.
