Elevated levels of CO2 make it difficult for plants to obtain the minerals necessary to grow and provide nutritious food..."Two main nutrients that are essential for human nutrition may be affected by this phenomenon. The first one is proteins built from nitrogen. The second one is iron."

IOW, Cell, like Lancet, isn't a reliable source for scientific information any longer.
Crazy talk. There are plenty of reasons to eat veggies for non-mineral reasons.
Also, one concern we all need to have is with bad mineral uptake by plants. For instance, fluoride is extremely high in most tea from China, while Japan does not seem to have this issue. Also, chocolate can be very high in arsenic, cadmium, and even lead.
Do we really want more toxic minerals in our plants? I didn’t think so.
Complete poppycock.
Learn the carbon cycle and understand photosynthesis or just shut up.
This has been reported in the past. What the article doesn’t say is that the small deficit in nitrogen is more than made up for in increased volume.
That’s why people pump CO2 into greenhouses, to make it difficult for plants to obtain the minerals necessary to grow and provide nutritious food.
Excellent advice, but they won’t listen.
Go confront 1,000 greenhouses....I doubt if you can find a single one that doesn’t use C02 in it’s operation now. You as a consumer....are actually paying for it to be added.
Since CO2 is soluble in water and the oceans cover a majority of the Earth's surface, the oceans sequester more CO2 than any other CO2 sink.
Because of the inverse solubility of CO2 with temperature, the colder the oceans get, the more CO2 they can absorb.
Conversely, when the oceans get warmer, they expel CO2.
Atmospheric CO2 therefore follows global temperatures, it does not cause them.
You can see the yearly atmospheric CO2 fluctuation in the Mauna Loa, Hawaii Observatory graph as the Pacific Ocean warms and cools with the seasons.
The "settled science" that CO2 is a "greenhouse gas" that causes "climate change" is therefore a complete and utter lie.
“Learn the carbon cycle and understand photosynthesis or just shut up.”
Perhaps you should also understand plant respiration.
I call BS. It’s all about the soil, sun, and water. Microbes in the soil are the most important as the help the plants absorb what’s in the soil. Good old compost, manure, ask anyone who gardens.
INCREASING LEVELS of coming up with silly theories while ignoring the air pollution being spewed out every day in China leads to severe mental illness.
My very FIRST question/response is to require the Institute for Plant Science to divulge the source of their funding for these studies, period. I was in university research for 30 years and that is always the first question if you want to know the validity of a ‘study.’
Agreed. And when I see this full court press for decreasing CO2 emissions that use bottom of the barrel/fraudulent justifications, it make me more obstinately opposed to the scam, even though I don’t think there is any possibility I could be even more in opposition to it than I already am.

Oh, I forgot, they're too busy fill kids heads full of crap that they have no time for science.
Plants grown under elevated atmospheric [CO2] typically have decreased tissue concentrations of N compared with plants grown under current ambient [CO2]. The physiological mechanisms responsible for this phenomenon have not been definitely established, although a considerable number of hypotheses have been advanced to account for it. In this review we discuss and critically evaluate these hypotheses. One contributing factor to the decreases in tissue N concentrations clearly is dilution of N by increased photosynthetic assimilation of C. In addition, studies on intact plants show strong evidence for a general decrease in the specific uptake rates (uptake per unit mass or length of root) of N by roots under elevated CO2. This decreased root uptake appears likely to be the result both of decreased N demand by shoots and of decreased ability of the soil-root system to supply N. The best-supported mechanism for decreased N supply is a decrease in transpiration-driven mass flow of N in soils due to decreased stomatal conductance at elevated CO2, although some evidence suggests that altered root system architecture may also play a role. There is also limited evidence suggesting that under elevated CO2, plants may exhibit increased rates of N loss through volatilization and/or root exudation, further contributing to lowering tissue N concentrations.
Half-baked hypotheses to promote Climate Change.
But...but...plants LIKE CO2! And return O2 to us via respiration!
I didn’t grow up on a farm, but my folks had a feed store. They also had spreader trucks, and custom blended fertilizer for farmers.
My stepfather talked about how most farmers don’t have enough land to let it rest, or plant a crop and plow it in to help the soil.
Some land is just played out.
