A broad statement like "trees consume carbon dioxide" would actually be an incredible paper to publish because it means that there is 1. a lot of interesting data that could back up a statement so broad and 2. extremely applicable to a wide variety of fields. When I say "uninteresting," I really mean a very specific type of uninteresting, like "sunlight does not affect the growth of the fungus Neurospora crassa. " It's uninteresting because it doesn't really tell us what affects the growth of the fungus, only that sunlight does not. If you got this result, you likely wouldn't even feel like it's information that's worth making public, hence the lack of papers that have these sorts of results. But, if it weren't published, then grad students across the globe would keep testing sunlight and keep finding the same thing again and again, wasting time and money. Hence the argument that all data should be published, regardless of how useless the results are
