1. Coastlines will have changed slightly due to sea level rise, and there will be less ice in the Arctic and around the periphery of Antarctica, due to climate change. Cities will be bigger, and there will be more of them.
2. A spaceship and the Earth are both closed systems with respect to the basic material needs of life - food, water, and air.
3. Assuming you mean material needs: food, water, and air.

Earth is a big place where the surface area is 510,065,600 km² and its total volume is 1.0832073Ã1012 km³. Where a spaceship is much smaller. I don't see any comparisons that are even remotely close. If you combine all the cities on the face of the planet it only amounts to 2 or 3 percent of the total land mass. Even with the expanded populated areas over the next 100 years won’t put a dent in our natural resources.
As far as living things on the planet, we will probably have more living things such as people, and animals to supply food, and more trees, because of managed Forrest's so we can build more houses, and products like baseball bats.

1) If you're talking about the coastline and stuff then about the same as it is today. Maybe a little flooding in low-lying areas but there shouldn't be too much of a difference.
2) I have no idea what you mean by this.
3) Food, water, air, shelter, sex, exercise/recreation, sleep.
