Which life? Industrial age humans? That's who we care about. Our goal is (or at least I hope it is) to enable humans to thrive, we don't really care about other life (at least if we had to pick between humans and other life) as long as it is not instrumental to our success.

The problem is that without the other life there can be no human life. We are on the top of the food chain and as such we depend on all other animals for our survival. Hopefully it makes sense what I'm saying.

Some other life, not all other life.

oddly enough some climate scientists (james lovelock, in this case) take it as a given that most animal life is already doomed, and that humans will have to engineer a food source in order to survive. green goo might be in your future

Soylent Green perhaps? http://en.wikipedia.org/wiki/Soylent_Green

Thriving is overrated.

Taking a contrary view: there are too many of us already. A smaller population will be more sustainable in the long term.

Unless you want unlimited growth with a huge apocalyptic human extinction event at the end.

In other words, I don't care specifically about industrial age humans. I want post-industrial and post-post-post-industrial age humans to survive too.

Eventually there will be some extinction event anyway. Is it more important to maximize number of humans who ever lived, or more important to maximize the age of the species? Your stated desires could mean either, but they prescribe very different strategies.
