An academic study has analysed the benefits to the environment and the population of the world that are possible through dietary change.
The food system is responsible for more than a quarter of all greenhouse gas emissions while unhealthy diets and high body weight are among the greatest contributors to premature mortality. Our study provides a comparative analysis of the health and climate change benefits of global dietary changes for all major world regions. We project that health and climate change benefits will both be greater the lower the fraction of animal-sourced foods in our diets. Three quarters of all benefits occur in developing countries although the per capita impacts of dietary change would be greatest in developed countries. The monetized value of health improvements could be comparable with, and possibly larger than, the environmental benefits of the avoided damages from climate change.
I witnessed examples of both yesterday - huge 4 wheel drive tractors carrying manure form farms growing meat.
1). The energy, machinery and load required to produce very little food per acre is alarming.
2). A video of motorcycle racing - and half the (extremely obese) crowd sitting in seats eating variations on the theme - meat in pastry.
By way of contrast, on one allotment 20 metres by 10 metres, it's fairly simple to grow much more than one person could eat in a year. If you add free range hens for eggs, you'd probably double the land required- that's all.
If you can - grow your own - you'll be able to trust what you eat ...
