Nobody starves to death because things aren't nearly as bleak for the super fleet as people think:
Unless the Quarians lost most of their liveships(garden ships) they can feed themselves. I don't think Earth's farmland is in that bad of shape because the Reapers focused mostly on population centers. The Quarians are really really good at sustaining a large population without a planet, so they can help everyone else.
Codex states Quarian Liveships were left at Rannoch. Don't ask my why they jump in in the cutscene - I don't know. However, seeing the size of them, they are big, slow, easy targets for the Reapers. However, I am willing to grant Quarian/Turian non starvation. They are the two that will get out of this Ok on the food side.
Now: Asari. They can't eat Quarian/Turian food. Earth is quite literally in flames - entire continents are made of fire ATM [Check the cutscene - behind the Reaper fleet the entirety of I believe America is in flames. Maybe Euro-Africa]. Did the Reapers focus on population centres? Yes. Does that mean farmland survived? Not so much. A lot of potential farmland will have been developed into urban areas pre the invasion, and out of the rest of the planet - forests, jungles and other such areas would likely take up a reasonable amount of the undamaged land. Could Earth produce food? Maybe. Could it produce enough for the 300,000,000 humans on it, the remainder of the systems Alliance fleet, the Asari, the Salarians, the Batarians and the Krogan? I wouldn't hedge my bets on it.
The Normandy crew doesn't have to look for civilization. The Normandy was making a relay jump and then on a world that humans can live on, chances are there is a colony on that planet.
2 things.
1: Not in Relay Transit. Relay Transit is almost instantaneous, and the cutscene goes on far too long for that to happen. The effects around the ship also resemble FTL travel more than Relay travel.
2: Chances are, there isn't a colony on that planet. Many places - like Virmire - would have been left alone due to political turmoil, and many others still wouldn't have been found. Statistically speaking less than 1% of the Galaxy has been explored in ME. The odds are vastly in favour of them landing on an unknown world.
Considering most systems that had relays or need relays are inhabited nobody has to spend 20 years going anywhere. As for how they do it: remember the communication system the Alliance put into the SR2 that allowed Shepard to communicate with anyone in the galaxy in realtime? I think they can make another.
There are a few problems with this:
1. Quantum Entanglement doesn't work that way. Not only is it difficult to create and maintain an entangled pair, but how would you entangle two communicators on opposite ends of the Galaxy?
2. Who is going to be able to build more relays? You would need a ton of Eezo, a lot of knowledge that the galaxy doesn't have and then the other additional resources needed to build one as well. Odds are, ports that are abundant with Eezo AND have good manufacturing centres would be able to make more Relays. To get them to the other side of the galaxy though... problematic. That is a 20+ year journey.
3. Nowhere near most systems with Relays were inhabited. Hell, we hadn't even opened up most Relays. As said, 99% of the galaxy is unexplored. The council put limits on activating new Relays after finding the Rachni when they went round activating them all. Humans trying to reactivate a Relay led to the First Contact War. Now, most systems that would need a relay put in them would be inhabited - but a large number of them would not be self sustained. Many are either stations, industrial or mining colonies, or Residential colonies that rely on farming colonies for food. That food is now cut off. Yet more starving people, and dead, starved people can't rebuild a Relay.
