The advancement in technology improved economy from past many years but do you think it will grow forever or their will be reduction in resources?
Some say the large population spike around the oil industrial revolution occurred due to technology advancing to a point where a larger population could be sustainable. There has been much said about "peak oil". Will civilization be sustainable once a point of peak oil production has passed. Humanity relies upon oil for pesticides, fuel, plastics, lubricants, crop fertilizer, energy. These applications might have fueled the large rise in human population growth. What happens if a reduction in resources has a severe negative effect on food production or other necessities people rely upon for survival?
There has been a long unanswered question about what happens when limited resources are consumed. Can innovation invent new ways around this basic problem? Might resources be harvested from asteroids or other sources? Perhaps we will see a painful and messy population correction if basic necessities like food are unable to sustain population growth. I don't think anyone has definitive answers to this. Its one of those unpleasant topics people avoid discussing.
I know that ways have been found to create gasoline and jet fuel from bio waste products. Plastics can be harvested and recycled back into oil. Peak oil may not be as much of an issue today as it was a few decades ago. There does seem to be a significant decline in the amount of arable (farmable) land in the world. Ah eff it. There are too many variables to this. I can't even begin to guess what will happen or what the key points here are.
