with a honeybee and that tiny, little bug — the marchalina hellenica — it would not survive if it was not for all of these trees. it's a precious ecosystem that desperately needs protecting. continuing myjourney of extreme conservation, i am in the mountains of east turkey. i have travelled 1,400 kilometres from the aegean coast to sarikamis on the armenian border. in winter, this area is popularfor skiing, but it is mainly a farming region. over time, lots of forests have been felled for pastures, leaving just a patchwork of trees behind. but i am here as this is home to turkey's majestic migrating brown bear.
