The given line graph illustrates the amount of oil production worldwide, measured in million barrels per day, across four regions over 40 years.
Overall, it is clear that there was an upward trend in all regions, with the Middle East witnessing the most dramatic rise, while the remaining three parts of the world showed relatively stable or modest growth.
The amount of oil generated in Africa started at around 15 million barrels each day, after which it experienced a fluctuation between 30 and 22 million barrels per day in 1970 and 1980, respectively, followed by a sharp rise to around 37 in 1990 and continued to increase to a peak of 40 million barrels per day. Regarding North America, approximately 5 million barrels were produced each day at the beginning of the period, with a subsequent increase to roughly 28 million barrels per day in 1980, followed by a final steady growth to a peak of around 32 million barrels daily.
Concerning the Middle East, there were only 20 million barrels produced in 1960; the figure consistently rocketed in the next 40 years and reached a peak of around 55 million barrels each day at the end of the surveyed timeframe, which made it hold the lion’s share among the four surveyed parts of the world. By contrast, the amount of oil barrels produced started at 5 million in 1960, after which it saw a consistent rise for 40 consecutive years and reached a peak of 20 million barrels per day; however, Asia still had the lowest level of oil barrels produced over the surveyed timeframe.
