If the world wants to control global warming, water shortage and pollution, then we all need to welcome “flexitarian” diets, say scientists.
This means eating mainly plant-based foods, and is a key step toward an environment friendly future for all in 2050, they say. Food waste will need to be halved ad farming practices will also have to improve, according to the study arid out by the Intergovernmental Panel on Climate Change (IPCC). Without action, the influence of the food system could increase by up to 90%
The authors say that he present food industry has a number of considerable environmental effects including being a great driver of climate change, using up freshwater and causing pollution through heavy use of chemical fertilizer. The study says that thanks to the population and income growth expected between 2010 and 2050, these effects could grow between 50-90%. This could push our world beyond is planetary boundaries, which the authors say represent a “safe operating space for humanity and the international community”.
However, the study finds that no single solution will avoid the dangers, so a combined approach is needed. So when it comes to climate change, the authors looked at what they called a “flexitarian” diet.
“We can eat a range of healthy dies but what they all have in common, according to the latest scientific evidence, is that they are all relatively plant-based,” said Dr. Marco from the University of Oxford. “You can go from a diet that has small amounts of animal products (some might call it a Mediterranean-based diet; we call it a flexitarian diet) over to a vegetarian(素食的) diet—we tried to stay with the most traditional one of these which in our view is the flexitarian one, but even this has only one serving of red meat per week.”
If the world moved to this type of diet, the study found that greenhouse gas emissions(排放物) from farming would be reduced by more than half.
Dr. Marco says that all measures combined can result in keeping both the planet and people healthy.
