Tread Lightly! is a non-profit organization in the United States with the mission of responsible outdoor use with the use of "ethics, education and stewardship". Tread Lightly! is supported by individuals, small business and corporations. As off-roading with vehicles such as ATVs, off-highway motorcycles, snowmobiles and four-wheel drives like Jeeps and pickup trucks is becoming more and more popular, it poses more of a threat to the natural resources. Off-road vehicles are only a part of the problem that Tread Lightly! addresses. All outdoor recreation poses a threat to the ecosystem. People who engage in activities such as camping, hiking, fishing and hunting need to be careful in the outdoors so as not to destroy it for others.
