The graph below shows changes in global food and oil prices between 2000 and 2011.

The diagram compares the

food

price index with the average price of a barrel of

oil

over the world between 2000 and 2011.

It is clear that

there was an

overall

upward trend for both global

prices

of

food

and

oil

over a period of 11 years.

Furthermore

, both

prices

increased very

similarly

and their correlation was about 93% It is clear from the graph that the figures for both increased slightly in the six first years.

However

,

oil

cost rose sharply from 60

dollars

in 2007 and peaked at 130

dollars

in 2008 and

as a consequence

, the

food

cost

also

followed but did not peak until later. But suddenly,

prices

of

oil

fell to 40

dollars

in the next year and

food

was 140 points compared with 221 points in the previous year. In the

last

two years, the

prices

grew again but the

food

cost reached a peak of nearly 240 points

this

time

while

the

oil

was around 100

dollars

.
