The issue with quibbling over impact is my experience is that people end up doing neither. I recently started a Master's in ecology so I don't have a good idea of what's cost effective right now but I know the field is pretty shockingly underfunded (both for general research and conservation projects). I learned the "fun" fact recently that bird populations in the US are down ~30% in the last 55 years.
