I have noticed that all the trees and plants are dead in Fallout 3. All but small brown looking shrubs are left. I have seen no crops growing anywhere but in Oasis. In F1 and F2 the people had Crops (mutated Corn) and such. In F2 there was a Farm with alot of Mutated corn and Apple trees. There were other plants as well that they grow. There were living trees all over in the other fallout games.
I can't see people living off nothing but Meat in the capital capital wasteland for 200 years. In the Fallout world food does have a very long shelf life. Pre-war food and drink can last a very very long time I know that. After 200 years and no one making any new pre-war like food, the supply of pre-war food would have been long since eaten up.
So I am asking how could people live for that long without plants? and why are there no plants no crops but in Oasis?

1: Have you visited the lab in Rivet City? Plenty of plants there.

2: Plenty of Plants and farms just a short sail away.

3: Game Logic. What you see isn't all there is.

The plants in Rivet City were not edibale, the farms in the games have no crops. Why are there no living trees anywhere but in Oasis? In other fallout games living plants were everywhere and edible some even tried to kill you.

Plenty of living plants in Point Lookout. They're even got a fruit growing industry going.

That is true, and I enjoyed playing Point lookout but it is an expansion. It's like afterthought. I think they did not add living trees and plants so they could have Oasis and therefore have a tie in with their game oblivion. I enjoyed Point lookout because there was colours ie: trees and plants. I have alot more reasons for enjoying Point lookout then that.

Well, technically speaking, it took millions of years for us to have developed the 0₂ concentration in our atmosphere that we currently have (less than 25%... close to 23%.) Even if all oxygen production was shut off, and we had large fires going for years, it would still take thousands or tens of thousands of years for the oxygen to go below breathable levels. Considering that there's still plantlife elsewhere in the globe (farms in FO2,) and the plants from Oasis (as well as whatever Mutfruit comes from,) it's unlikely that the FO world will ever run out of breathable oxygen.

At any rate, it's been said that Brahmin eat scrubgrass (which is a hardy form of grass.) And theres plenty of Scrubgrass out in the wasteland. So...

Well that is interesting but I was speaking more from a nutrition point of view. People can't just live on meat all their lives not with out big health problems and over generations that would just get worce and worce. scurvy would be a health problem one among many.
I once read about a theory if I can find the info I will post it. The theory was by American Scientists that if there was multiple nuclear detonations at once that it may ignite the oxygen in the atmosphere. In all I was talking from a nutrition point of view.

The un-radiated plants in the Lab of Rivet City were. They were just like regular plants and vegetables, no radiation added. And I suggest you look up Harold, on the Fallout Wiki (if you haven't already.) It explains why there are only trees in Oasis, and not the rest of the CW.

I know all about Harold thank you. I have been saying all along that besides Oasis there are no trees. so I thought by saying that, Harold would be implied. Again I am saying that Bethesda made it so there would be no trees to make Oasis more relevant and people would be like cool a "Tie in with Oblivion!"

I'm not much of an Oblivion (TES in general) kinda guy, so that reference kinda goes beyond me. I thought why Beth added Harold, was to tie-in with FO1-2 more. I mean he was in both of them, and both showed stages (I believe) of him. So why not add him? But I'm missing the Oblivion tie-in?

Well I agree he is a Tie-in to the other fallout games I like that Harold is in F3 in some way. As for Oblivion well Oasis looks alot like the game Beth made called Oblivion. Google or Wiki it and you just may see my point. I am not trying to step on your toes.

I've played the game, just never really got into it is all. I just don't see how Harold/Oasis, tie-into looking like Oblivion? I mean didn't the two games use the same game engine or something? And I think it's kinda hard for a game company, to change the look of their trees. So really, I don't see a tie-in? Explain to me if you could, how it does.

Yes they use the same engine and things will look the same. I just think the point of Oasis was to have a small Chunk of Oblivion in Fallout 3. To me when I see Oasis I think Oblivion. So Beth made the wasteland have no green trees to have Oasis stand out. to me the whole thing is a "wink wink nudge nudge" to Oblivion fans. This all may sound like a crazy conspiracy but that is my stand on it.
This does take way from the point. How can people live without Plants, I see that the people in DC have been living on Junk and Meat for 200 years. I have made my points on that already.

If I have have upset Oblivion fans that was not my intention.

One can live without being /healthy/. It's called 'living in the third world'. Then again, I'd rank the living conditions below even that. As far as vegetables go, yes, there are those in Rivet City, and there are Mutfruit plants around the wastes, even if you yourself don't /see/ them. Keep in mind it's just a video game, and while they've created an immersive world, they may have left details out. Like how the whole DC area is amazingly tiny compared to it's real-life counterpart. Or why there's squirrel on a stick and iguana on a stick, but neither of these animals are ever encountered living. So it's no far stretch to imagine there are plants people can eat, albeit rare and mutated.

And I honestly don't get how Oasis is an Oblivion reference. Reaching a little far to make a connection, aren't you? Green, healthy trees are not exactly something limited only to Oblivion, and the idea behind Oasis was to provide a hidden, though sharp contrast to the dried out badlands of the rest of the wasteland. For why it's happening, well, blame Harold!

Seriously though, you're getting far too worked up about this. When in doubt, step away from your computer, take a deep breath, and sing this little song:

"If you're wondering how they eat and breathe,
And other science facts.
Just repeat to yourself it's just a game,
I should really just relax."

Well even in the 3rd world they have vegetables and fruits and I know of the point lookout stuff, it has been talked about. Anyways I will keep your song in mind. I will try to relax more. As for the Oasis thing well it's my crazy conspiracy.

or simply dont try to think about it, since it cant be explained in a good way anymore.

A simple answer is that, the location is called the Capital Wasteland for a reason; It's supposed to be barren and desolate. I'd imagine that there are parts of the world that still have living plants, albeit irradiated and/or mutated. As for the question of how fruits and veggies get into the CW, I go with that the Caravans play a much bigger role in the game world then shown. Bringing in foods from far off farms.

Punga fruit, crunchy mutfruit, and for the most part a diet of fresh radroach, mirelurk meat, mole rat, people, and dog meat. I think the Wastelanders would lean slightly more carnivore than omnivore over time as the lack of vegetation would dictate. Too bad even irradiated processed foods can't last more than 10 years. A Twinkie only lasts 1.5 years. The processed antique food mechanic was a pet peave with this game for me. Not only wasn't it feasable, it ate up inventory, and wasn't all that nutritious.

Pre-War food some how lasts 200 years I don't have a problem with it because it's clear that in the Fallout universe that scientist before the great war found a way to have most food Last a very long time. But after 200 year it would have been eaten by now and there should be none left. That goes for Nuka Cola as well. I have excepted the idea that fruits and vegetables could and are coming in from other areas out side of the DC area. It would have been nice to see more plants. To bad you can't grow any punga fruit back in Megaton house or Tenpenny. maybe we can I just have not tried to take one of the potted punga fruit in point lookout.

I'm guessing a lot of the food is coming from other places through traders and visitors to the Capital Wasteland. For all we know, just outside of the map boundaries and over a hill, there could be a huge farm growing all kinds of vegetables. We don't know, but I personally assume traders are the answer and the fact they travel all over.

I have come to except that explanation.

Yeah, unfortunately, it's the only real plausible explanation despite it being really sketchy and horrible. Nevermind.

Other than simple "Game Logic"

Tobar always brings a haul of Punga Fruits. There is a confirmed source of unradiated plants in Rivet City which they are presumably trading, and a mention of pears in Tenpenny as well. Although we never see them grow there also exists mutfriut and crunch mutfruit (mutated graqes and apples)

capital wasteland got the worst of the nuclear attack obviously, the survivors scavenge off the remnants of the past, food that could only feed hundreds of thousands for a day, can feed a few hundred survivors that are still alive for lifetimes
