Could you imagine a world without the Grand Canyon, The Great Barrier Reef or the Amazon? For the planet, some places are indispensable - it's quite simply a matter of life and death.

In Bartels Beard, a young tree surgeon embarks on an epic 100-day journey to visit seven of the world's most extraordinary natural wonders. The one thing he doesn't pack is his razor. From the serenity of myriads of butterflies in Mexico to the roar of the erupting Kamchatka volcanoes. From the freezing glaciers of Greenland to the scorching plains of Tanzania. Bartels Beard takes us to seven far flung corners of the world where nature can't help but put a show. But is the date of the very final performance closer than we think? He brings back the verdict. And a 100-day beard.
