Why it's a good idea to fill galaxy with life? Why should we care about it? Also, seeing that our current civilization-system is already at the brink of catastrophe, we should focus on less ambitious goals, such as preserving life on Earth.

1. I don't want my children to die. And i don't want all the life on earth to be eliminated by a random asteroid.

2. Imagine two planets, people on one of them believe that expanding is the moral imperative, and the other want stay where they are. Eventually the people from the first planet will be technologically as far away from the people on first planet, as we are from people on Sentinel island. And therefore will be completely reliant on goodwill first people.

3. The only way to preserve life on earth is to develop space technology, once we have sufficient industry in space, controlling whether on earth will be a simple task, trivially solving climate change issue.

Absolutely worth it. We wont fill the galaxy filled with life because the galaxy is huge and we are but one tiny tiny portion of it. For us to survive and do anything impressive takes all of human ingenuity.

Also those two items aren't mutually exclusive. Both can and should happen in tandem. Anyone arguing otherwise is just a mentally lazy person.

Whenever you have two goals competing for the same resources, you need to prioritize. I'm for preserving life on Earth first, and spreading it to other places as a distant second.

Again you aren't competing for the same resources. Our global resources are plenty. You are unnecessarily making a dichotomy.

Of course preservation of life on our planet should be paramount. We can also pursue space travel. Space travel research isn't whats killing our planet.
