There's a good example of this concept involving horse manure - "In the 1890s the key environmental concern was horse manure. London had 11,000 cabs and several thousand buses, each using 12 horses per day - more than 50,000 horses in public transport alone. Each horse produces 15-35 pounds of manure per day; New York had 2.5 million pounds per day to shift, and in 1894 The Times predicted that every street in London would be 9ft deep in dung within 50 years."
The flaw here is not so much disregarding the invention of other means of transportation, but assuming that the dung will be taken care of exclusively by putting it in the street without any removal.
the grobe but that is only if moores law is correct. I mean the house prices in america also didnt rise forever.
Yeah, that was the point of my post -- you can do the math and get to something that seems reasonable based on some assumptions, but those assumptions are fundamentally flawed.
