American technology?

No offense intended Rebgirl, but thats too narrow-minded. This whole thing should be a global concept because it's a global problem. If we as a species just hang out on earth for too long we'll all eventually die from who knows what kind of astonomical event.
Since we are talking about the future of the species it is the resources of the entire species that should be utilized.
I realize that the idea of a truly international research team for interstelar travel probably isnt feisable right now but hopefully in the not too distant future we can pull our collective head out of our collective ass and get together on the important issues.
Like this one.
