Examination Questions Geography – Mr. Fagan


A) Explain why oil exploration in the area shown could lead to high economic and environmental cost.

B) Assess the relative importance of named players in the global supply of energy.


A) Oil exploration in the areas such as the Amazon could lead to high environmental costs due to the fact that there are a lot of ecosystems in the area, oil exploration may lead to destruction of these ecosystems which may endanger the species. Permanent damage may be done as it may be difficult for the ecosystem to be rebuilt. 

As well as this, deep water drilling is also required in places such as the Arctic, this is perhaps a sensitive and delicate procedure as new technology may be used to carry out the deep water drilling and by chance an oil spill may occur. Following the BP oil spill in the Gulf of Mexico it showed that oil spill can once again be a great danger to water species and birds, it is a major pollutant of water itself, 20 years on from the oil spill in Exxon Valvez, Gulf of Alaska, toxic crude oil was found hiding under the rocks of 13 miles of coastline.

Such accident majorly affects the fish industry and also a mass of oil which could have been used is now wasted.

Oil exploration is expensive in itself due to the fact that heavy machinery and energy is used in order to conduct the deep water drilling, also, converting the unconventional oil such as tar sands from countries such as Canada into conventional oil may also require a lot of energy.

This energy used creates a lot of CO2 emission which is a major cost to the environment as it is one of the main contributors to the green house gases which contributes to the global warming.

Converting unconventional oil in areas such as the USA into conventional oil may be hugely expensive, this is a major economic issue, as well as this they are very open to exploitation in the area which perhaps may lead to dispute, however, in poorer areas such as Somalia, they will benefit from the high prices that may be set which will enable them develop .....

Such energy types such as nuclear energy cause a problem when it comes to its disposal due to the fact that it takes thousands of years before it is actually safe consumers may also complain and protest against this due to health and safety issues for them and generations .....
