Lolz, please don't talk about agriculture because we do not even generate enough agricultural products to even sustain us here talkless of shipping it outside the country ,that will be ridiculous.lolz. even the crude oil that you are talking about, is it not even the white people that helps us to discover it and refine it for us.As I told you earlier, we generate crude oil, which can serve as fuel to machines, solar plants and automobile. We are into agriculture too, most of our crops, food produces are shipped to outside country as well. Nigeria is also blessed with precious metals like Gold, silver, and diamonds etc, which can be found in the northern States. All this things are income generating and productive to other countries too, but we aren't using it well, few are enjoying it and many are suffering.
