Nutrition in 2050—Increased CO2 Changing Plant Nutrients
Low levels of dietary iron and zinc can facilitate a multitude of assaults to the human condition. When humans are lacking in these nutrients, they can suffer a weakened immune system, anemia, low IQ, and reduced energy levels. Approximately 2 billion people suffer from iron and zinc deficiencies worldwide.
Recent experiments based on wheat, peas, soybeans, and rice have shown that high levels of CO2 decrease the plant material’s iron, zinc, and even protein levels between 5 and 10%. Unfortunately, these are the crops that supply 70% of these nutrients to a hungry and malnourished planet.
Just this April, carbon dioxide levels were recorded for the first time (since records have been kept) at or above 400 parts per million across the entire northern hemisphere. This is 150% of the levels in pre-industrial times – in about a 100 year span. A nanosecond in geological time.
The experiments elevated the carbon dioxide levels to between 546 and 586 ppm. This is the level that scientists expect to see in some parts of the world by around 2050. Projected population in 2050 is about 9.6 billion (up 38% from 2010).
With all these mouths to feed – and nourish – humans will be hard pressed to fulfill their dietary needs in the future. Perhaps we could ban together and make some changes.
It’s a small planet…
