I am scientist with a PhD in ecosystem ecology. My primary areas of research are soil chemistry, forest ecology, and microbial ecology, but my focus is on biogeochemistry. I am also very interested in human nutrition and physiology, as well as geography and mountaineering. I think that more effort should be made to cite primary sources in wikipedia, because the "telephone game" of citing secondary sources and the introduction of loaded adjectives can completely misrepresent the state of our knowledge. Importantly, government web pages, magazines, and newspaper do not represent primary literature. They may be good secondary sources, but they are secondary sources. At the same time it is important to acknowledge that many areas are un- or under- studied, and the absence of scientific evidence to support claims is not evidence of their illegitimacy.
