Explore the new economics of tourism in this travel-themed edition of the magazine, where we examine how climate change is reshaping our itineraries. Some travellers are visiting glaciers before they disappear, while others are using their holidays to remove trash from the environment. Some are drifting toward the poles as they pick cooler climes instead of the traditional equatorial getaways. And it’s not just humans changing course – other species are on the move too, like trees, insects and even great white sharks.
