Lab notes: Rising carbon dioxide levels can cause protein deficiency in millions of people

New research indicates that India may lose 5.3% of protein from a standard diet by 2050, if atmospheric carbon dioxide rises as projected.

People in eighteen countries may lose more than 5% of their dietary protein by 2050, if carbon dioxide levels continue to grow as projected. This is because increased carbon dioxide levels in the atmosphere will lead to a decline in nutritional value of rice, wheat and other staple crops.

While researchers have previously pointed to the link between rising carbon dioxide and falling nutritional content of staple crops, scientists from the Harvard TH Chan School of Public Health in the United States have now quantified the decline. They estimate that roughly 150 million people may be placed at risk of protein deficiency because of elevated levels of carbon dioxide in addition to those who are already not getting enough protein.

Globally, 76% of the population gets most of their daily protein from plants. The research team set out to estimate their current and future risk of protein deficiency by combining data from experiments in which crops were exposed to high carbon dioxide concentrations with global dietary information from the United Nations and measures of income inequality and demographics.

The study published in the journal Environmental Health Perspectives shows that elevated carbon dioxide concentrations lead to decreased protein of 7.6% in rice, 7.8% in wheat, 14.1% in barley, and 6.4% in potatoes. According to the results, the loss of protein will hit countries in Sub Saharan Africa and South Asia, including India, where millions of people already suffer from protein deficiency and where rice and wheat a large part of daily diets. The researchers found that India may lose 5.3% of protein from a standard diet, possible putting 53 million people at new risk of protein deficiency.

The researchers say that their findings highlight the need for countries that are most at risk to actively monitor their populations’ nutritional needs and for them to curb human-caused carbon dioxide emissions.

A phone so stunning that it deserves its own photoshoot

Presenting the Moto X4, crafted to perfection.

Precision-crafted glass and metal design, an anodised aluminium frame, easy to hold and featuring beautiful contours, the Moto X4 is crafted to perfection indeed.

With the distinctive placement of the rear cameras, this phone makes a great subject for a photographic series.

Reclining on a bed of satin, the glass-encased phone blends into the folds of the luxurious fabric.

The slimness, seamlessness and solidity of the phone make for a great profile shot.

A stunning design which is IP68 rated water-resistant too, it is as beautiful as it is strong.

We partnered with photographer Gaurav Sawn to create this series. Says Gaurav, “The glass sandwich design looks extremely good and the reflections on the back panel make the phone stand out. This is a phone that is best used without a case. The curved corners were also very comfortable to hold. All in all, really enjoyed shooting this phone!”

While this phone is elegant and crafted to perfection, it is also extremely tough, being protected from scratches with Corning® Gorilla® Glass that stretches all the way around.

You don’t need to sacrifice of performance either. It’s packed with a 2.2 GHz octa-core Qualcomm® Snapdragon™ 630 processor and comes with a TurboPower™ Charger which means hours of power in minutes!

For the music lover, this phone is a boon. With simultaneous connectivity of up to four Bluetooth® audio devices at the same time, you can build your own stereo system without worrying about cables.

The dual rear cameras – a 12MP that lets you focus faster and get great results even on dark, cloudy days, and an 8 MP camera, with wide angle lens makes your most ambitious photos look all the more impressive.
