A picture of Moon Ji-sung, a high school student who died in the Sewol ferry disaster, hangs in her room in Ansan April 7, 2015. Her dream was to be a flight attendant. Nearly a year after the Sewol ferry sank on April 16, 2014, with the death of 250 students, some families keep their children’s bedrooms intact to remember and honour their loved ones. More than 300 people, most of them students and teachers from Danwon High School, are dead, or missing and presumed dead, after the Sewol ferry sank on a routine trip from the port of Incheon, near Seoul, to the holiday island of Jeju.

An aerial view shows the Amazon rainforest at the Bom Futuro National Forest near Rio Pardo in Porto Velho, Rondonia State, Brazil, September 3, 2015. The town of Rio Pardo, a settlement of about 4,000 people in the Amazon rainforest, rises where only jungle stood less than a quarter of a century ago. Loggers first cleared the forest followed by ranchers and farmers, then small merchants and prospectors. Brazil's government has stated a goal of eliminating illegal deforestation, but enforcing the law in remote corners like Rio Pardo is far from easy. (Photo by Nacho Doce/Reuters)

Rangoli, also known as kolam or Muggu, is a folk art from India in which patterns are created on the floor in living rooms or courtyards using materials such as colored rice, dry flour, colored sand or flower petals. It is usually made during Diwali, Onam, Pongal and other Indian festivals. They are meant to be sacred welcoming areas for the Hindu deities. The ancient symbols have been passed down through the ages, from each generation to the next, keeping both the art form and the tradition alive. Similar practices are followed in different Indian states: in Tamil Nadu, there is Kolam in Tamil Nadu; Mandana in Rajasthan; Chaookpurna in Chhattisgarh; Alpana in West Bengal; Aripana in Bihar; Chowk pujan in Uttar Pradesh; Muggu in Andhra Pradesh and others.
