Here's the point, but let me briefly digress and I will watch the film again in the next day or two to get my facts right because I saw it more than a year ago, maybe longer. It came out in 2014.
Are you up on the cutting-edge research they're doing and learning about the microbiome, how we have billions of microscopic bacteria in our bodies that keeps us healthy, and why people are into kombucha and other fermented foods and drinks? Well, my understanding is the GE products are engineered to resist Roundup Ready, which in turn kills all other (I don't if it's a total wipeout), but many of the countless micoorganisms that live in the soil and that not only are beneficial but essential to its health -- according to Symphony of the Soil, this does erode the topsoil of many of these important microorganisms that promote soil health. Now you say it doesn't, but it does kill all the competitors of the GE product, correct? Why don't you watch the movie because it explains this a lot better than me and I will watch it again, but it might be of interest to you. It discusses the issue with farmers, agronomists, soil scientists, etc. You have more understanding of this, so if there is bias you would be able to detect it better than me.
