Space debris isn't a new problem or something that's coming entirely out of the blue. NASA has almost certainly built it into the plans and engineering to keep ISS going for years and years. The fact they do maneuvers, keep meticulous track of large debris, etc. is a great sign that the systems they have in place are working. I'd honestly be more worried about the political capitol and will to spend money on the space program drying up more than debris strikes.

Depends on how much money you wish to donate or how much skilled you are. Other than that I don't think there is much need for “ordinary” civilian to create FUD regarding this in online forums.
