First, it seems clear that even if there are occasional small dips in the consumption of petroleum, the general trend shows no sign of a real permanent decrease. Second, petroleum reserves are not being discovered as fast as petroleum is currently being consumed. From these two facts we can conclude that reserves will eventually be consumed and that the world will have to do without oil.

Answer 2

How do I explain the answer please?

Answer 3

True beyond a reasonable doubt; it may be that
consumption will drop in the future or that discovery of new reserves will increase, but as

eventually all the oil will be used up.
