• The rising atmospheric CO2 levels not only impact the air quality but also cause micronutrient deficiencies in plants which when consumed consequently lead to “hidden-hunger” among human beings.

• Studies have shown that the additional carbon leads to higher concentration of starch and a decreased concentration of proteins and nutrients in the crops, particularly in global staple foods such as rice, wheat, potatoes, and barley.

• A 2018 study published in Frontiers in Plant Science found that with rising carbon levels, protein levels drop by nearly 10%, iron by 16%, zinc by about 9%, and magnesium by about 9 %.

• Way Forward:

1. Decreasing atmospheric CO2 levels

2. Food Fortification- India led a successful venture in this regard with the distribution of fortified rice with vitamins and minerals such as iron and zinc in its food security programmes.
