Scientists have noticed that in many kinds of plants, higher #CO2 produces bigger crops. That sounds like a good thing.
But there’s a problem. Bigger doesn’t necessarily mean better. And while they’re still testing what this means for coffee’s quality, scientists have seen that other crops have lost some of their nutritional value under higher CO2 conditions.
One example is rice, a primary food source for more than 2 billion people.
Carbon dioxide (CO2) levels this century will alter the protein, micronutrients, and vitamin content of rice grains with potential health consequences for the poorest rice-dependent countries | Science Advances
