Today, the world is small. I can live my life in London, UK, and still attend family events in Sweden, where I'm from, several times a year. I can have my cake and eat it.

Trying to avoid these emissions, I have experimented with ferry and train travel between the UK and Sweden for over a decade. But plane is almost always the cheapest option. So what about cycling?

Cycling helps us appreciate nature, says Brandi Horton, vice president of communication at the US non-profit Rails to Trails Conservancy. "When you're zooming around in your car or you're on the train or you're on a plane, you are not going slow enough to notice what lives [around] you.
