A major environmental downside to travel is the carbon footprint it leaves but there are movements underway and things we can do individually to minimize this impact. One of the biggest polluters are airlines, which emit 3.5% of the world’s carbon emissions. While that might not seem like a big percentage, reducing emissions in this field is important, and sustainable aviation fuels are key.

Until last week, I understood over-tourism to be an urban problem, limited to cities like Edinburgh, Rome, Paris, New York, Sydney, or Barcelona. I was forced to re-evaluate in the most unlikely of locations—a beautiful beach on the Outer Hebrides of Scotland, about as far away from the likes of a global metropolis as you could possibly imagine.
