Sara, born in Sweden's far north, travelled through 50 countries before settling in Alberta's Bow Valley. She is attracted to the world's more remote places and is passionate about the need to care for them.
"I've witnessed so much beauty but also poverty, inequality and environmental destruction and I'd love for my photos to contribute to the change necessary to reverse that," she says.
Her photograph will be exhibited at the Royal Geographic Society in London this summer.
