Images such as these can be found in Delta, Bayelsa, and Rivers State. Extracting oil causes underground shifts that allow pockets of natural gas to escape and this gas is lit on a fire as means of eliminating it, causing the gas flares that are in some of these photos. They can burn for months and years, and in some communities families cook with them. In total, there are 50-100 flares across the Delta and some are so large they can be seen from space. The amount of gas burns up could power a large part of the Africa continent if it was harnessed usefully. Local residents are not keen to vent the natural gas because it is so much less valuable than oil.
Globally, oil-related gas flares emit about 390 million tons of carbon dioxide every year, and experts say eliminating global flaring alone would curb more CO2 emissions than all the projects currently registered under the Kyoto Protocol’s Clean Development Mechanism.
