The hard part about scientific articles is that most of them are pay-to-play, and therefore hard to share; it's easier to share reports from UN agencies and nonprofit institutions. Therefore, if you want to learn everything there is to know about biodiversity and health, look no farther than a 2015 report done by UNEP (United Nations Environment Programme), CBD (Convention on Biological Diversity), and the WHO (World Health Organization).
The report is massive - 364 pages - but provides a solid base of knowledge. Considering that my research is focused on nutrition and agrobiodiversity, I focused on the sixth chapter.
For those of you who aren't convinced, this is a great place to start looking into the importance of biodiversity not just to human health but also for the planet as a whole.
Here's the link to the complete report:
