What happens when Mother Earth gets too crowded?

we will start to explore living in other planets. This is what the scientists are doing now, exploring other living planets so that in time to come, part of our population can move there.

Life inside an spaceship - a different perspective NOW

since young, we have been instilled with the idea that life in spaceship is exciting and fun...being in powersuit and ability to float around,

but the movie doesn't seem to depict the above.

The frustration of being caught in a system wide power failures inside the spaceship, poor lighting system.

The eerie of being surrounded by rampaging mutants/cannibalistic monsters.

The feeling of groping in darkness and unaware of what is/are hidding inside the darkness; uncertain of what/when/how something may suddenly pound on you and grip when you are totally unexpected.

What do you do when you wake up one day with no memory, trapped in a deep-space for long periods of time and are in an isolated environment?

claustrophobia...... loneliness...... survival...... psychosis...... paranonia...... distrust...... helplessness......

A dark and realistic movie about life in a spaceshuttle, about transporting manforms to another living planet to prevent overpopulation on Earth, to resolve the issue of lack of resources and to introduce a war-free environment......
