China, Brazil, and India are solving main problems and their incomes are rising, while countries like Congo, Cuba, and Kenya have stagnant economies and leaders not addressing hunger and debt.

Renewable energy sources will also be needed as scientists say gas and oil will run out within 30-40 years requiring reduced consumption.
