0109 nigeria
Protesters gather at Gani Fawehinmi Park in Lagos during a demonstration against soaring petrol prices following government's decision to abolish decades-old fuel subsidies, on January 9, 2012. - 

Imagine if you woke up tomorrow morning, and the price of gas down on Sunset had risen from $3.49 to over $7 bucks a gallon.

That's the kind of situation that Nigerians are now finding themselves in.

Last week, we learned that the government of the oil-rich African nation decided to put an end to fuel subsidies. And now Nigerians are fighting back: labor unions there have begun a national strike today.

He says that for gas prices to double, especially in such an oil rich country, can have catastrophic results on everyday life for Nigerians -- and why we should care.
