“Two Brothers”. We found about 20 lions eating a buffalo. When the male leaved the group we anticipated him to take photos. It is 8AM, light is perfect and the position too. The lion stops and looks down from the hill, another lion is coming up, it stiffens, I think that will be a fight, i'm tense, the camera is OK, the shots previously made perfect. The two meet, looking directly into their eyes, they sniff, rub against their heads, the tension drops, they start walking with the same step as when they were puppies, they are two brothers. Photo location: Masai Mara, Kenya. (Photo and caption by Massimo Mei/National Geographic Photo Contest)

Olive Ridley turtle hatchlings (Lepidochelys olivacea) sit in baskets and trays at the turtle camp La Gloria, before their release into the ocean in Tomatlan November 15, 2013. Twenty years ago, Mexico's government implemented ecological plans to protect the sea turtles from being hunted for their leather and meat and established conservation areas and a pay system for local residents to protect turtle nests. Millions of baby turtles hatch on the shores in November and December, according to an environmental group. It is estimated that in 2012, there were 20 million newborns. Hatching season is still underway, but officials say they expect there will be even more turtles born this year. (Photo by Alejandro Acosta/Reuters)

“The ONE Campaign is a international, nonpartisan, non-profit organization which aims to increase government funding for and effectiveness of international aid programs. ONE was originally founded by a coalition of 11 non-profit humanitarian and advocacy organizations — including DATA, World Vision, Oxfam America, and Bread for the World — with funding from the Bill & Melinda Gates Foundation. In 2007, ONE announced that it would be merging with DATA. Currently, ONE is campaigning for resources to help developing countries adapt to climate change. During the 2008 U.S. presidential election the organization launched a campaign, called ONE Vote '08, which was co-chaired by former U.S. Senate majority leaders Tom Daschle (D-SD) and Bill Frist (R-TN). The campaign is named after the U2 song “One” which was a top ten hit single on the critically acclaimed 1991 Achtung Baby album”. – Wikipedia
