Declaration of the scientific consensus for veganism

A declaration of a scientific consensus for plant-based living would provide rationale to governments and industry to change their policies related to food, and to individuals to recognise the changes they can make to their diets.

Scientific consensus has been reached that our world is warming and that this warming is mainly due to human activity, spurring governments, industry and individuals alike to seek ways to reduce their carbon footprint. Food is central to our existence, and our food production systems are central to achieving ecosystem balance. Global consumption of animal products is increasing, with emerging economies embracing western diets, putting additional pressure on the environment. As such, we require an intergovernmental, scientific-based consensus focussed on finding the optimal food system mechanisms that work to maintain ecosystem balance, while providing good nutrition and not exploiting others. This consensus would encourage development of international agreement on the massive changes that will need to be implemented within the global food system.

Food systems have significant environmental impacts including on carbon emissions, soil degradation, pollution and biodiversity. Recent research indicates that a major change individuals can make to reduce their carbon footprint is to eat a vegan diet. A growing body of nutritionists agree that humans can derive all required nutrition from a vegan diet. Additionally, there is scientific consensus that animals have sentience, which, within the current framework of ethics, should be sufficient to end animal farming practices in many regions.

I propose the development of an Intergovernmental Panel on Food Futures (IPFF) to overlap with and complement IPCCs current outputs on food security and food production. The IPFF would draw on international expertise from ecosystem scientists, nutritionists, food technologists, sociologists and biologists to reach scientific consensus on the key branches of food production including ecosystem impact, nutrition and animal welfare.
