Higher the CO2, lesser the nutritions

high_co2According to a recent study, crops in high CO2 atmosphere will have less nutrition in them. This a very serious issue for the future. Scientists usually predict that the yields of crops could be raised by higher atmospheric CO2, but its nutritious value will decrease . Samuel Myers of Harvard University has reported that the CO2 levels in coming years will probably reduce the levels of iron, protein, zinc etc in crops like rice, wheat and soybeans. The study found that nutrients changed unequally when CO2 was higher. Another experiment at the Long’s university shows that rising CO2 levels lowers the resistance of crops to pests. Myers suggests there should be a worldwide effort to develop new breeds of crops that show resistance to higher CO2 levels.
