The map, issued by the Center for Disease Control (CDC), shows the percentages of substantially overweight, or obese, low-income children by county and in territories and tribal organizations where Native Americans live. The problem extends to both urban and rural populations.

Overall, 1 in 7 low-income, preschool-aged children is obese. Experts have been alarmed by the rapid rise in childhood obesity during the past 20 years, which is attributed to changes in diet toward more processed foods, less physical activity, and low-income families' lack of access to highly nutritious food. The impact of obesity on life expectancy, increased incidence of diabetes, heart disease and other ailments is reason for its recent prevalence as a public health issue.

Public attention to decreasing childhood obesity includes efforts to enhance the nutritional balance in school lunches, nutritional education for children and adults, pressuring food corporations to improve labeling and ingredients, and campaigns to increase children's physical activity by reducing time in front of television and computers and restoring daily physical education classes or recess.

The carved stone relief is from the interior of Candi Mendut, a Buddhist temple in Central Java. Mendut was built during the early Shailendra dynasty in about 824 CE. It may have been built on the site of a Hindu temple from a previous century. The rectangular, stone temple is 26.4 meters (86.6 feet) tall and is constructed on a 2 meter (6.5 feet) platform. The surrounding wall is covered with reliefs that relate stories from Buddhist teachings along with lush carvings of plants, fruits, and flowers. This relief is one of a pair showing the goddess Hariti and her husband Kuwera.

Hariti, depicted in the south panel, is a symbol of good fortune and fertility, but this was not always so. The narrative of Hariti represents the dangers of childhood mortality. In a story with several versions, Hariti was a, ogress, or demoness who had many children, but who hunted and ate human children. One day, the Buddha hid her children and as she searched frantically to recover them, she saw the evil of her ways. She repented and became a guardian to children and a symbol of fertility and good fortune.

The relief panel, shown in many Buddhist temples, depicts Hariti sitting on a bench with a child on her lap and another climbing onto her shoulder. Children play all around her, helping each other climb fruit trees and enjoying games. Under the bench is a bowl of mangoes, a symbol of fertility. Parrots fly above her head. Hariti’s cult as a special guardian of children and women in childbirth traveled widely, expressing the ever-present threat of death especially to children. Hariti is known in Central Asia and in China, and possibly even Japan, where she is similar to the protective boddhisattva Kannon.

The definition of an orphan for statistical purposes is a child under 18 years old who has lost one or both parents. A single orphan is a child who has lost one parent, a double orphan is a child who lost both parents. A maternal orphan is a child whose mother died, while a paternal orphan has lost the father. Crises such as disease or famine that affect children increase the rate of growth of orphans in the population. For statistical purposes, children are no longer considered orphans after they reach 18 years of age. Therefore, the number of orphans in a population group increases if the number of children losing their parents exceeds the number of orphans turning 18, causing the percentage of orphans in that population to rise also.

The data in the two charts were compiled and published by UNICEF, the United Nations Children’s Fund, drawn from numerous organizations concerned with the global AIDS/HIV epidemic. As the bar graph shows, while the number of orphans in Asia has declined during the period from 1990 to 2010 (the latter based on projections), and has remained fairly stable in Latin America and the Caribbean, there has been a steady increase in the number of orphans in Sub-Saharan Africa. Data is not given for the number of children in Asia who have been orphaned by HIV and other causes, but that figure is likely significant.

Figures for Africa show that in the benchmark years of 1990, 1995, 2000, and 2005, the percentage of children orphaned in sub-Saharan African countries as a result of AIDS rose sharply from 1% to 7% to 17% to 25%, and is projected to reach 30% of all orphans by 2010. Among them are over 10 million children who have lost both parents. AIDS is the leading cause of death among adults ages 15-59, and it has produced 12 million orphans in the region. The rates of HIV deaths are not uniform across Sub-Saharan Africa, but are much higher in southern Africa, where as many as 15% of all children are orphans. Behind these figures is a tremendous toll of human suffering. Older children may act as caregivers for their parents or siblings who are ill, or grandparents may have to raise their grandchildren. Poor nutrition, inability to attend school, inability to concentrate, emotional trauma and depression are among the most serious effects, and children whose families have been touched by AIDS may also be stigmatized by others, further worsening these effects.

Father Alberto Maria De Agostini, a missionary, took this postcard image on Isla Grande, Tierra del Fuego, on the southernmost tip of South America. The photograph, taken circa 1930, shows a man, woman, and two children walking through a clearing surrounded by thickets. The man and boy are carrying bows and arrows, and the younger child walks close to his or her mother, who is carrying bundles on a frame on her back. The family members wear robes made of guanaco hide, a South American animal similar to a llama. The woman and children are barefoot. The man wears shoes of fur-covered hide and a cone-shaped hat.

This family belongs to the Ona tribe, or Selk'nam, whose existence in the area near the Strait of Magellan can be traced back at least 9,000 years. The Ona, one of several distinct tribes in the region, lived as hunter-gatherers. Europeans have known of this group since Magellan named the land after their fires, which he saw burning on the coast. Charles Darwin described them in the journal of his voyage on the Beagle. Since then, missionaries have visited and lived among them, settlers have displaced and even hunted them, and anthropologists have attempted to study them to understand life in the Stone Age. Death from diseases brought a sharp drop in their population, which had numbered in the thousands. According to the last census of native populations in 1965, only 300 Onas remained. The last full-blooded Ona person died in 1995 in Argentina.
