Increasing atmospheric CO 2 concentrations cause mineral deficiencies in plants, making them less nutritious to eat. This is stated in a study by specialists from the Montpellier Institute of Plant Industry in France, reports Phys.org
As the scientists explained, plants use carbon dioxide for energy, but the process does not provide crops with nitrogen, phosphorus and iron. Most plants get these elements from the soil.
As CO 2 concentrations increase, plants begin to consume more carbon dioxide and rely less on minerals from the soil. This can lead to crops grown with excess carbon dioxide containing 20-30% less protein and iron.
This situation can lead to food problems in developing countries, where a significant part of the population receives most of its nutrients from plant foods.
French researchers believe that it is necessary to develop new crops that are less sensitive to the negative effects of greenhouse emissions.
