Yes, I do think that it is important to preserve these life forms.  Besides being valuable as genetic codes that we can study, these are forms that once had a purpose.  If they had a purpose, there may be something in the future that we need them for.  Either way, they should not be forgotten.

Yes, we probably should.  However, this is probably just a sentimental sort of a thing.  We cannot possibly preserve a significant amount of every kind of biome. For example, all we have of American prairie is little bits that are essentially museum pieces.  I think that this sort of preservation just makes us feel a bit better and gives us the possiblity of going and looking at how things used to be.  This is nice for us, but probably not scientifically/envrionmentally relevant.

I think we should make every effort to try to preserve the biomes and ecosystems that are present with us now.  Understand, over time, the ecosystems and biomes have evolved; change in some form or fashion is inevitable.  The things we tend to do ourselves, however, such as degrading the ozone layer in the stratosphere as a result of air pollution should be held in check and limited.  I saw a newsclip just the other day talking about the shrinking availability of glacial ice at the poles.  One typically does not think about saving icy domains, but there are organisms, such as the polar bear, that call such domains home.  The polar bear population has now dwindled to such numbers as to be on the verge of extinction, much of which can be attributed to an ever-shrinking availability of hunting ice.  This ice is slowly but surely melting away as global temperatures continue to creep upward.  The only way our children will be able to see polar bears in the future, if we are not careful, will be to see them in captivity, or see video footage of them.
