History
By the 1960s and 1970s, outdoor recreation was becoming more popular, following the creation of equipment such as synthetic tents and sleeping pads. A commercial interest in the outdoors increased the number of visitors to national parks, with the

seeing a five-fold increase between 1950 and 1970, from 33 million to 172 million.
Articles were written about the wild being “loved to death,” problems with overcrowding and ecological damage, and the need for management. To solve this, regulations were imposed, including limits on group sizes and where camping was allowed. This was met negatively, with people writing that it took the joy and spontaneity out of wilderness recreation.
The focus was shifted towards education, with the

Principles
# Plan Ahead and Prepare
#* Know the regulations and special concerns for the area you'll visit.
#* Prepare for
extreme weather

#* Schedule your trip to avoid times of high use.
#* Visit in small groups when possible. Consider splitting larger groups into smaller groups.
#* Repackage food to minimize waste.
#* Use a map and
compass
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with No ...

# Travel and Camp on Durable Surfaces

areas by camping at least from lakes and streams.
#* Good campsites are found, not made. Altering a site is not necessary.
#** ''In popular areas:''
#*** Concentrate use on existing trails and campsites.
#*** Walk single file in the middle of the trail, even when wet or muddy.
#*** Keep campsites small. Focus activity in areas where vegetation is absent.
#** ''In pristine areas:''
#*** Disperse use to prevent the creation of campsites and trails.
#*** Avoid places where impacts are just beginning.
# Dispose of Waste Properly
#* Pack it in, pack it out. Inspect your campsite, food preparation areas, and rest areas for trash or spilled foods. Pack out all trash, leftover food and litter.
#* Utilize toilet facilities for defecation whenever possible. Otherwise, deposit solid human waste in
catholes dug 6 to 8 inches deep, at least 200 feet from water, camp and trails. Cover and disguise the cathole when finished.
#* Pack out toilet paper and hygiene products.
#* To wash yourself or your dishes, carry water 200 feet away from streams or lakes and use small amounts of biodegradable soap. Scatter strained dishwater.
# Leave What You Find
#* Preserve the past: examine, photograph, but do not touch cultural or historic structures and artifacts.
#* Leave rocks, plants and other natural objects as you find them.
#* Avoid introducing or transporting non-native species.
#* Do not build structures, furniture, or dig trenches.
# Minimize Campfire Impacts
#* Campfires can cause lasting impacts to the environment. Use a
lightweight stove for cooking and enjoy a candle lantern for light.
#* Where fires are permitted, use established
fire rings,
fire pans, or mound fires.
#* Keep fires small. Only use down and dead wood from the ground that can be broken by hand.
#* Burn all wood and coals to ash, put out campfires completely, then scatter cool ashes.
# Respect Wildlife
#* Observe wildlife from a distance. Do not follow or approach them.
#* Never feed animals. Feeding wildlife damages their health, alters natural behaviors,
abituates them to humans and exposes them to predators and other dangers.
#* Protect wildlife and your food by storing rations and trash securely.
#* Control pets at all times, or leave them at home.
#* Avoid wildlife during sensitive times: mating, nesting, raising young, or winter.
# Be Considerate of Other Visitors
#* Respect other visitors and protect the quality of their experience.
#* Be courteous. Yield to other users on the trail.
#* Step to the downhill side of the trail when encountering pack stock.
#* Take breaks and camp away from trails and other visitors.
#* Let nature's sounds prevail. Avoid loud voices and noises.

Criticism

While Leave No Trace is a widely accepted
conservationist ethic, there has been some criticism. In 2002, environmental historian James Morton Turner argued that Leave No Trace focused "largely on protecting wilderness" rather than tackling questions such as the "economy,
consumerism

, and the environment", and that it "helped ally the modern backpacker with the wilderness recreation industry" by encouraging backpackers to purchase products advertising Leave No Trace, or asking people to bring a petroleum stove instead of building a natural campfire.
In 2009, Gregory Simon and Peter Alagona argued that there should be a move beyond Leave No Trace, and that the ethic "disguises much about human relationships with non-human nature" by making it seem that parks and wilderness areas are "pristine nature" which "erases their human histories, and prevents people from understanding how these landscapes have developed over time through complex human–environment interactions". They posit that there should be a new
environmental ethic "that transforms the critical scholarship of social science into a critical practice of wilderness recreation, addresses the global economic system...and reinvents wilderness recreation as a more collaborative, participatory, productive, democratic, and radical form of political action". They also write about how "the LNT logo becomes both a corporate brand and an official stamp of approval" in outdoor recreation stores like
REI.
The authors articulate their new environmental ethic as expanding LNT, not rejecting it all together, and share the seven principles of what they call 'Beyond Leave No Trace':
# Educate yourself and others about the places you visit
# Purchase only the equipment and clothing you need
# Take care of the equipment and clothing you have
# Make conscientious food, equipment, and clothing consumption choices
# Minimize waste production
# Reduce
energy consumption
Energy consumption is the amount of energy used.
Biology

# Get involved by conserving and restoring the places you visit
In 2012, in response to critiques of their 2009 article, Simon and Alagona wrote that they "remain steadfast in our endorsement of LNT’s value and potential" but that they believe that "this simple ethic is not enough in a world of global capital circulation." They write that Leave No Trace "could not exist in its current form without a plethora of consumer products;" that "the use of such products does not erase environmental impacts;" and that LNT "systematically obscures these impacts, displacements, and connections by encouraging the false belief that it is possible to 'leave no trace'".
Other critics of Leave No Trace have argued that it is impractical, displaces
environmental impacts to other locations, "obscures connections between the uses of outdoor products and their production and disposal impacts" and have questioned how much the ethic affects everyday environmental behavior.
