1) Because it will make much more sense to live in free space (IE on an asteroid or space colony) where you avoid the huge energy cost of going up and down a gravity well.
Humans need gravity to exist for a prolonged time. Our skeleton, internal organs, muscle etc. all depend on it. Unless you in some way emulate gravity in a satisfactory way, living in free space is impossible.
The only way to make sure is to demand thorough documentation of the manufacturing process and ensure the authenticity of the documentation provided. Consumer pressure is needed to make companies deliver green products on a regular basis. They will manufacture what the buyers want. Governments are usually important customers and can lead the way on behalf of the public.
As a side note, one should also demand that the products are "fair", such as the manufacturer and subcontractors don't exploit third world countries, the workers are properly paid etc.
Question: Who the hell funds these projects? And why?

This seems like a good opportunity to mention the famous Web 2.0 FAQ by Rich "Lowtax" Kyanka on somethingawful.com. For those readers who are not entirely sure what web 2.0 is:Question: What is Web 2.0?
Answer: Web 2.0 is a combination of Web 1.0 and being punched in the dick.Question: How do I know I'm using a website / service / product that is officially "Web 2.0" and not actually "Web 1.0" with various patches and enhancements added to it?
Answer: Web 2.0 is made obvious by the addition of completely and highly unnecessary bells and whistles that don't do anything besides annoy you and make life more complicated. If Web 1.0 was the equivalent of reading a book, Web 2.0 is reading a book while all the words are flying around and changing pages as the book rotates randomly and sets your hands on fire. Also there's this parrot that keeps on flying towards your head in repeated attempts to gouge out your eyes.Question: I read about this one website in Wired Magazine. Is that Web 2.0??
Answer: Oh definitely. Wired won't even mention Web 1.0 sites. Every single site in their magazine is at least Web 2.0. Sometimes they're even up to Web 45.2 (such as www.ebutts-and-credit-reports-delivered-via-carrier-pidgeon.com)!Question: My roommate said he "digged" a "wikipedia entry" about "the blogosphere" which mentioned "podcasting" as a viable form of "crowdsourcing."
Answer: Your roommate is a faggot. Also, this wasn't technically a question.Question: What's Web 3.0?
Answer: It's a product or service planned on release in spring of 2008, and consists solely of websites enabling the user to create even more detailed Kirby ASCII art. (O'.')-o
Promising costs nothing, it's the delivering that kills you.
