I do not know the situation in Nigeria. The general issue is that the demand for goods exceeds the available sustainable produced goods, and the trend is that the difference is widening. The demand grows faster than the production and the scissor is opening.
One level deeper, the demand grows fast because of the:
- population growth,
- the growth in GDP/Capita,
- high demand in increasing purchasing power, western patterns in wealth accumulation.
The sustainable technologies and infrastructure is not there yet, and the missing connection (torn) between wealth and sustainable production makes sustainability goals undeliverable. In the case of developed countries, the gap looks smaller and narrowing (a part of that is exported environmental burdens of course).
