Table 18.4 lists the average daily oil production for the year 2002 for major oil-producing countries.It can be inferred from this table that the USA exploits its resources to a much larger de- gree in proportion to her known reserves,compared to most other countries (see Figure 18.3 and Table 18.4).Figure 18.4 depicts the world oil consumption from 1980 to 2002.The prices for plas- tics depend largely on the price of oil which fluctuates consid- erably over the years (mostly for political reasons).Figure 18.5 depicts crude oil prices from 1981 through 2003. To complete the overall picture,Table 18.5 provides the pro- duction figures and reserves for coal. It is alarming to note from Table 18.2 how fast some of our presently known reserves would deplete if the current consump- tion remains at the same level and if no new sources are discov- ered.This may be particularly true for oil,as shown in Figure 18.6. However,exploration efforts for the past 50 years have consistently yielded additional crude oil reserves that even exceed consump- tion at present,as depicted in Figure 18.7.Reserves are defined as deposits that can be profitably exploited using current tech- nologies at current prices.In other words,the reserves are directly affected by the market price.Moreover,deposits that are not ex- ploited within 20 years are considered to have little significant fi-this, Table 18.2 also lists the production and consumption data for crude oil and coal.
