Earth’s changing climate is expected to have many repercussions that are sure to alter our way of life. Now, a new study concludes that, in 2050, half a million people will die as a result of under-nutrition — a result of climate change.
The study, published in The Lancet on Wednesday, concluded that reduced fruit and vegetable consumption could result in under-nutrition across the planet.

Up to three-quarters of the deaths will occur in China and India, according to the study.
The issue isn’t the availability of food — which many studies have examined already, warning of dire consequences. Instead, this study focused on the health effects of reduced food nutrition as a result of a decline in food availability.
“Much research has looked at food security, but little has focused on the wider health effects of agricultural production,” Marco Springmann from the Oxford Martin Programme on the Future of Food at the University of Oxford said in a release.
“Changes in food availability and intake also affect dietary and weight-related risk factors such as low fruit and vegetable intake, high red meat consumption, and high body weight. These all increase the incidence of non-communicable diseases such as heart disease, stroke, and cancer, as well as death from those diseases.”

The research was done using an agricultural economic model together with socio-economic pathways, emission trajectories and the possible resulting climate responses. Using the collected data, they calculated the number of deaths that would be linked to dietary changes.
The model showed that unless action is taken to reduce global CO2 emissions, the change in climate around the globe could cut food availability by about one-third by 2050. This would result in an average 3.2 per cent reduction in food availability per person, which would translate to about 99 kilocalories a day.
When it comes to fruit and vegetable intake, they estimate that it would be a four per cent reduction (almost 15 grams) a day. For red meat it would be a reduction in consumption of 0.7 per cent (0.5 grams) a day.

Canada doesn’t escape the repercussions: It ranked 63 on the list of 155 countries.
