This is one of my favourite travel quote🙂It means that while we are travelling in nature, we should leave no trace of human intervention like plastic bags, personal things, paper, food cover etc. Its prime responsibility of every hikers, trekkers, travellers and tourists to respect the ecological and geographical beauty of every place. Everyone should try to balance nature in its original condition by just leaving their footprints rather than their personal use of things or other degradable and non degradable waste. The nature does not belong to any man instead every man belongs to nature🙂
