The only reason I see why there should be any shortages for anything, is for the "war effort"

If they live underwater, they can use desalination to get water. Recycling technologies would have to advance for space living (IIRC they are quite good now, but are not implemented), and so contaminated groundwater shouldn't be a problem.

Really, with all the energy being produced they would have no issues with water availability.

Other than that I like your ideas!

Forgive my mystipos, it is realy hard to type properly with a touch screen, next time i'll do it from my PC.

Well, it is a natural thing. It happened before but unfortunately we are trying to make a movie and it is an already seen idea. Have you ever seen Total Recall? or Adjustment Bureau?, what about Minority Report? They use already seen ideas but projected in a different manner. And yeah, all written by Philip K. Dick, big fan. I don't say get rid of the idea, i just say turn it into a twisted thing.

My concept is this: Turn it into an actual situation but projected in a more dystopic version of it. Thin goes like this (and this is to make sense with my Pennfield idea):

After a new sort of enterpreuners have emerged it was the same time of Mars artificial terraforming was taking effect. Mars now was ready to be inhabitaded by humans, at least for the stronger because martian air was too light for beeing breethable but it was enough. The problem began when the Mars Project was demanding enormous resources and a world civil war was about to take place. The new political power took control, they called themselves GOVDOGs (government dogs). It was a facist movement who blamed the enterpreuners for the crisis, instead of the government who spent too much in Mars, but they didn't spent all in Mars, corruption, can you see my point?

Just like in WWII when endles crows of people where sent to death camps, the enterpreuners were sent to Mars, so the GOVDOGS always have thought it was a useless project anyway. Yeah, they were sent to die. But theese guys adapted to Mars. As bussines men and people who can put aside emotions they learn to live from Mars resources and created a new peaceful and prosper society.

When GOVDOGs realized martians became even more richer while back in New Earth (as govdos calk it after getting rid off the wealthy class) situation was too dam bad. Hungry spread everywhere, people just killed each other for just a taste of soup. GOVDOGS killed millions just to spare some food by a "random" process. They daily played a game just like lotto at public TV or the futuristic for of it and those who were selected they where just executed. But they food saving process was not just and austerity thing, it was another form of corruption, they just keep more food for themselves and used ti sold the leftovers for a high price.

So envy was burning inside govdogs and they launched a propaganda against the people in Mars telling people something like "Martians are Killing New Earth, so let's kill martians". In other words, they were bkamin Mars people of New Earth problems. But martians were not stupid. They were prepared, they were alway one step ahead because they have lear from history and as bussines men and women they were used to have everything under control. Martians had agents on New Earth and a huge group of counter govdogs were helping martian cause.

So, govdogs assembled a big army, almost 3 million troups (three time the biggest army in history) and thousands of spaceships. It was a disaster. Martians with just 10 000 troups defeated govdogs army something like 6 Day War in 1967. But govdogs didn't admit defeat and told people that Mars was New Earth control. The problem began when surving fighters brought back martian deseaces and a global break out started to kill trillions of people. So govdogs, blaimed Mars again but it was a big mistake because govdogs lies were finaly exposed. So the still govdogs loyals while they were fighting the rebelion, they finaly admited they could not hold situation forever. So they called for a global referendum where people where fooled to decide to revoke or not govdogs governship. But the real votation ended as a destroy or not destroy Mars with a big nuclear weapon. Finaly people voted to kill Mars, they were too tired to keep on fighting anyway.

So a big Nuke was built, while millions were dying for starvation or just because Mars Plague, as they called.

But an Alien invation avoided that calamity. Aliens forced both sides to finaly live in peace and this is the farest as my imagination can go.

Well, Philip K. Dick novel does not explains neither why people must artificialy must force emotions. Maybe it is just superstition, they just need to feel emotion for the fear of being retired (in therms of the novel and the movie) because the androids whom are ilegal in earth are just shot upon detection, and androids have no emotions.

Maybe in this film, emotionlessness was considered a new form of atheism and it was cool for a while but then consequences of it where almost unbearable for non emotionlessness people, just as the few religious devoted people of today, and somehow the propaganda was manipulated by this few but powerful group and so there is a current that emerges telling that emotions are good. And as it happens today, people just go from an extreme to another, so the next step of extremism is the artificial emotion rush that leads to a mass disaster and so the Penfield device came to save the day and it was the method that worked for so long until a small group of people decide to control the rush of emotions by themselves.

I hope i've filled the gap in that story.

Wow, that's an interesting concept.. Especially, how the evolution of diseases affects our own evolution. There might be a scary truth to that, since we are coming up with new ways to combat diseases, they might find new ways of surviving.. attacking our emotions would be a good way to go.. but, what would be the driving force to people wanting to get back there emotions? I would think they would be rather indifferent.. because, after all, emotions are what has allowed us to reach this point in our civilization, but I imagine 1,000 years into the future, we may have no need for emotions, as all of our needs will be met in other forms, through the advent of new resources and technology.. and since you're open to suggestions as to what that part of our future would look like, I might be able to offer some insight.. computers will be far more evolved than us by that point, so we will be largely dependent on them for many tasks, such as architecture, education, advancements in science, transportation, food.. things we would normally have to work for will be given to us by computers.. killing animals for there consumption will be a thing of the past, since we will get all of our nutrition either grown in a lab or through our bloodstream or by some other means.. we may still have a need for social interaction, but socializing will be much different.. there will be a universal language that isn't left for interpretation and even animals will be able to use it to speak to us.. it will be perfect, like mathematics.. we will know substantially more about physics, which may lead us to the possibility of time travel, knowing how to manipulate gravity, instantaneous transport, total weather control, invisibility, among many other things.. technology will be far beyond most people's comprehension today.. we may be able to upload our brains into some type of universal server with virtual reality or some type of altered reality.. people may want to walk around as surrogate vessels (cyborgs..) medical science may allow us to live for hundreds of years or even forever, if we're able to upload our consciousness or exist in a timeless universe.. the boxes that we're used to living in will likely be spherical.. We'll live in the sea, on other planets, and even through other planes of existence (virtual reality, other dimensions, and other forms of consciousness..) You might be able to tell that this is one of my favorite subjects.. Today, the world is pretty messed up, but there's hope for tomorrow.. Good luck!
