Yes adverse impact of tourism is never thought in this way in a past that's why we have high value of 8 percent green house gas emissions. Unbelievable figure but it is happening due to our ignorance and lack of awareness. Cutting aeroplane is a daunting task but we can overcome other problem by eating and purchasing smartly. To develop better environment awareness is required so it's our duty to educate common people/tourist around our surroundings to avoid such acts which is source of climate destruction. @valth you are doing a great job by giving awareness to all steemians. Thanks for sharing @valth
