The Guardian UK reports that people will have to be rationed to four modest portions of meat and one litre of milk a week if the world is to avoid run-away climate change.
The report, by the Food Climate Research Network, based at the University of Surrey, also says total food consumption should be reduced, especially “low nutritional value” treats such as alcohol, sweets and chocolates.
It urges people to return to habits their mothers or grandmothers would have been familiar with: buying locally in-season products, cooking in bulk and in pots with lids or pressure cookers, avoiding waste and walking to the shops – alongside more modern tips such as using the microwave and internet shopping.
The United Nations has called on developed nations to reduce greenhouse gas emissions by 80% by 2050. The production of food in developed countries accounts for a significant portion of their greenhouse gases — an estimated 30% of the EU’s total emissions — and studies in the UK and the Netherlands show that the meat and dairy industries account for more than 50% of food-related emissions. A recent report by the UK-based Food Climate Research Network urges developed nations to reduce meat and dairy consumption by a drastic 70% so that global production remains stable as the world population increases.
