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.
