“On March 8th activists celebrate International Women’s Day, which dates back to the early 20th century and has been observed by the United Nations since 1975. In the run-up to the event, Reuters photographers in countries around the globe took a series of portraits of women and their daughters. They asked each mother what her profession was, at what age she had finished education, and what she wanted her daughter to become when she grew up. They also asked each daughter at what age she would finish education and what she wanted to do in the future. The series of images offers an insight into the lives of women and girls around the world”. – Reuters. (Photo by Feisal Omar/Reuters)

“Himalayan Dog”. This dog just appeared out of nowhere and followed us for an entire week during our trekking trip in the Himalayan outback. He always used to sleep in front of our tent and guarded us in the nights. When I decided to get up at 4 a.m. to climb the next 5000 m peak for sunrise he accompanied me as well. On the top he was sitting for the entire 30 minutes on this place looking straight into the countryside. Photo location: Ladakh, India.
