Excuse me, but if you actually READ what I told you, you'll see I make no reference to "Mother Nature". Technology can, and WILL, if left to capitalism, provide alternatives, IF NEEDED.
Will there be problems? Maybe - but it's not the apocolyse.
How do you draw that conclusion, though? Technological changes do not necessarily come in a regular, predictable manner, or at the rate we'd all like. We've got 6 billion people in the world, though, and the world population is growing very quickly. Not only that, but capitalism is making countries which previously lived in poverty much richer, and as they get richer, they demand more oil. The demand is escalating very quickly.
If you read most of these posts, they basically say, "don't worry, there is no problem." When people start saying that kind of thing, you can bet that there WILL be a problem.
