Nigeria lies on the west coast of Africa. The country is geographically diverse and its climate ranges from arid to humid equatorial.

The country also has plentiful natural resources, namely large deposits of petroleum and natural gas. Abuja is the capital of the country, in the Federal Capital Territory, which was established by decree in 1976. The former capital, Lagos, remains the country's main commercial and industrial city. The habitats in Nigeria are very diverse, from mangrove swamps and tropical rainforest to scattered savannahs dotted with clumps of trees.
