To be Green or not to be Green...

We are getting ready to do some remodeling in our home and we are weighing the positives and negatives of "going green" on some of the choices we need to make. Since we don't have too much experience in this area, I'm asking for your comments/opinions/suggestions.

Today we came upon an option for hardwood floors that is a "green" option. It is stranded woven bamboo from North China, which is supposed to be a renewable resource and more eco-friendly than other hardwood floor options. Bamboo does have a reputation of being very "soft", but apparently this stranded & woven version is "harder than oak". We did get a sample, and yes it is VERY hard and durable wood, which does bode well for us seeing as we have two 50lb dogs and a child .

Here are the downsides/questions we have:
Is this sort of bamboo actually durable?
We are unsure if it can be sanded & refinished...
Are there any other "green" options out there that are mainstream enough to increase the value of our home? We really would like to do hardwoods, though.

Any advice or ideas you have are welcome! Thanks!
