The huge amount of carbon dioxide we are producing and pumping into the Earth's atmosphere is causing much more damage than previously thought.
Rising CO2 levels aren't just responsible not for global warming; they also have a massive impact on the global food system, according to a Science Advances study.
An increase in carbon dioxide can significantly reduce the level of micronutrients in certain plants.
Researchers studied the effects of the gas on rice and it was found to contain significantly less protein, iron, zinc and B vitamins after exposure to the level of carbon dioxide our atmosphere is expected to harbor by the end of the century.
With several billion people on Earth already suffering from malnutrition, the repercussions of this would be devastating.
"Rice is a staple food source for about two billion people and the poorest of the population obtain over 50% of their daily nutrition in the form of rice," wrote Lewis Ziska, one of the authors of the study."Anything affecting the nutritional quality of rice will have serious effects."
The researchers point out that previous studies focused mainly on how climate change would change the cultivation of crops. "The quality of the plants and their nutrient content are just as important," says Ziska.
Ziska and his colleagues exposed rice fields planted for research purposes in China and Japan to increased carbon dioxide levels.
In doing so, they used values that, according to experts, will appear worldwide in this century as a result of humans.
The majority of the 18 test rice varieties contained significantly less protein, zinc, and iron than the rice cultivated today.
The researchers found that the content of Vitamins B1, B2, B5 and B9 has decreased dramatically in all varieties. However, the rice contained more Vitamin E.

Oh, so that’s why Tim Horton’s coffee is so repulsive to drink these days. And why I can’t eat KFC like I used to, lol.

Everywhere I turn, it’s The End.
It will also affect toilet paper too.
Fact is these learned institutions have lost all credibility. I don’t believe anything published. That’s a dangerous situation but academic papers are broken. Nothing can be believed.
What a crock.
Plants thrive in CO2.
So more plant food makes for less nutritious plants... okay Karen..
Plants grow better in CO2.
Nature will reach a balance all the time. More CO2, and plants grow eating up the CO2, which tends to reestablish the balance.
What a crock of crap.
A global malfunction of newtrision!
So, in other words, it's a "study" based on someone's alarmist fabrication?
So all the megafauna in the past grew to great size by eating foods less nutrient dense than what grazers eat today?
