The problem is that saying "we need to do something" is equally unhelpful because "we" isn't a thing that takes action in any ordinary sense of the word. You are just putting words together in a syntactically correct order that are devoid of actionable meaning. The way this sentence is normally interpreted is, somebody needs to do something, but it's not clear who that somebody is, or what power they need in order to act on a large enough scale to be effective.
If you can't say with any clarity what action needs to take place and by whom, then you aren't really contributing to a solution. Reacting to a fire in a house is much easier because it is clear how individual action can help. For example: you can call the fire department, I can get a fire extinguisher. Notice the word "we" is not in those sentences.
