Mona dreams that all the water on earth dries up and all the trees are cut down. The chapter uses this dream to illustrate:

AThat technology can replace any resource
BThat even RENEWABLE resources can become very scarce if not used carefully — and that non-renewable resources can be exhausted entirely
CThat dreams predict the future
DThat deserts are inevitable
Answer & Solution
Correct answer: B. That even RENEWABLE resources can become very scarce if not used carefully — and that non-renewable resources can be exhausted entirely
The point of the dream is to make abstract sustainability concrete. Even renewable resources like water and forests can be depleted or degraded faster than they regenerate, especially under heavy human pressure. Non-renewable resources (oil, coal, minerals) are at risk of exhaustion in the foreseeable future. This is why conservation and sustainable development are not optional but essential.
