The Copenhagen Consensus is a project that seeks to establish priorities for advancing global welfare using methodologies based on the theory of welfare economics . The participants are all economists, with the focus of the projg a rational prioritization based on economic analysis. The project is based on the contention that, in spite of the billions of dollars spent on global challenges by the United Nations, the governments of wealthy nations, foundations, charities, and non-governmental organizations, the money spent on problems such as malnutrition and climate change is not sufficient to meet many internationally agreed targets. The highest priority was assigned to implementing new measures to prevent the spread of HIV and AIDS. The economists estimated that an investment of $27 billion could avert nearly 30 million new infections by 2010. 
“ At the moment, the colonial government left Nigeria, there was no doubt in the minds of oil Rivers people that natural resources and in particular, lands, petroleum resources and other economic potentialities belonged to the autonomous people of Nigeria where they were and we had no misgivings of the magnitude that a petroleum decree and land use decree would emerge, whereby all the most important natural resources of our people would be confisticated by the central government and be left with ridicular 3% of the huge revenue that our territory produces. We cannot bear this any longer”.
