Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area. With 1.4 billion people as of 2021, it accounts for about 18% of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Africa an important economic market in the broader global context.

The Tchimpounga Sanctuary, also known as the Tchimpounga Chimpanzee Rehabilitation Center, for primates is located on a coastal plain of savanna and forest in the Republic of the Congo, and was built in 1992. The site covers an area of 70 square kilometres (27 sq mi). The sanctuary, part of the Jane Goodall Institute, is located 50 km north of Pointe-Noire in the Kouilou Department and is the largest chimpanzee sanctuary on the African continent. It has conducted research comparing food-sharing and social inhibition among chimpanzees and bonobos.

The Jane Goodall Institute (JGI) is a global non-profit wildlife and environment conservation organization headquartered in Washington, DC. It was founded in 1977 by English primatologist Jane Goodall and Genevieve di San Faustino (1919-2011). The institute's mission is to improve the treatment and understanding of primates through public education and legal representation, to protect their habitats in partnership with local communities, and to recruit and train young people for these missions.

It is bordered to the west by Gabon, to its northwest by Cameroon and its northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to its south by the Angolan exclave of Cabinda and to its southwest by the Atlantic Ocean.

In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of offspring and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s that is frequently used in sociobiology and evolutionary biology circles. The term often implies either a lifelong socially monogamous relationship or a stage of mating interaction in socially monogamous species. It is sometimes used in reference to human relationships.
