The Delta region has a steadily growing population estimated to be over 30 million people as of 2005, accounting for more than 23% of Nigeria's total population. The population density is also among the highest in the world with 265 people per kilometre-squared (reference NDDC). This population is expanding at a rapid 3% per year and the oil capital, Port Harcourt, along with other large towns are growing quickly. Poverty and urbanization in Nigeria are on the rise, and official corruption is considered a fact of life. The resultant scenario is one in which there is urbanization but no accompanying economic growth to provide jobs. This has led to a section of the growing populace assisting in destroying the ecosystem that they require to sustain themselves.
