10% is a very big deal. We talk about trying to 'eat healthy', but what happens when all your food is becoming less healthy? This is a tragedy of a worldwide commons. Because it's not just rice, extrapolating from it, this is something that affects all plants globally. And it isn't just humans that are affected: this affects the animals that eat plants. What happens to environmentally stressed endangered species who now get less nutrient value from what they eat? This isn't an isolated study: people have been looking at this (albeit with little funding) for 20 years.
