Im a Film student and I'm currently working on a idea for a film involving a world after global warming and the deconstruction of civilisation. Whilst my ideas won't all be realistic to the Nature of a possible post apocalyptic world. I want to get some things right. such as; a realistic year that those who 'survive' would begin to create small civilisations and groups again? What would realistically still be around and usable in terms of modern day technology and living? And what major changes would be in the new world?
ideally if you have any links to sources and even more information that would be great!
