According to a new study that made the rounds last week, going vegan is the answer to many of the worlds most pressing problems. If everyone stopped eating animal products, researchers predict that millions of lives, trillions of dollars €” and the earths climate €” could be saved.
The study, published by the Proceedings of the National Academy of Sciences of the United States of America (PNAS) and carried out by Oxford University researchers, addressed several potential scenarios for a change in worldwide eating habits, including if everyone went vegan. €œIf that were to happen you could save about eight million lives by 2050,€ Dr Marco Springmann, one of the studys lead authors, told Latest Vegan News. €œYoud reduce food-related greenhouse gas emissions by about 70 percent; and youd reduce healthcare bills by about $1.5 trillion.€
And while these stats are compelling, whats even more notable is the fact that stopping climate change is next to impossible without addressing the food issue in a global way.
Overall, when it comes to climate change, just a little bit of dietary change isnt enough, Dr. Springmann says. Reducing energy consumption also wont be enough. The world would need to make a dramatic shift towards more plant-based foods in order to avoid a dangerous rise in global surface temperature.
€œAction that would reduce greenhouse gas emission are urgently needed. The latest IPCC report, as well as the annual emissions gap report that is based on it, have highlighted the scale of keeping global warming below 2C at the end of the century. Greenhouse gases, in particular carbon dioxide, stay in the atmosphere for a long time, so we need to act fast. Methane emissions from agriculture are shorter lift and could provide a good starting point for making some progress on reducing the concentration of greenhouse gas emissions in the atmosphere. But that would mean taking seriously the climate change impacts of agriculture and our diets.€
€œWe dont expect that everybody would go vegan or would be willing to go vegan but surely one has to think very creatively about what role plant-based diets can play and how those can be supplemented by technological advantages and reductions in other emissions,€ he adds.
So why hasnt food been seriously addressed by world leaders? After all, it was essentially ignored at the Paris climate talks earlier this year. €œI think food hasnt featured prominently so far because policy-makers and industry have focused on the production side of the economy, in particular on the energy sector which on its own is the largest emitter of greenhouse gas emissions,€ Dr. Springmann says. €œHowever, food systems become important when looking at the consumption side of the economy. Adopting a consumption-based perspective allows for a more detailed discussion on why we produce emissions in the first place. And it is really the consumption side of the economy that describes how our lives look.€
All in all, the research shows that plants must be the future of food. The earths survival likely depends on it.
In the words of Dr. Springman: €œI hope the numbers we provide and the huge benefits that we estimate would make policy makers and industry individuals seriously consider what could be done and really discuss frameworks that would encourage more plant-based eating.€
