Roughly 20 years ago, Svetlana Kazina quit her job in the city to follow her true calling -- nature. She and her two kids moved to a wooden hut in the mountain village of Uznezya in Russia's Altai Krai region, near the border with Kazakhstan. Their new home was built almost seven decades ago. It had no heating, no toilet, no running water. But it had what the city couldn't offer them. Peace and harmony.
