plant-based diet, health and climate change



An academic study has analysed the benefits to the environment and the population of the world that are possible through dietary change.

food study

Their conclusions:

organic food, farming biodiversityThe 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 ...

  1. #organicfood Vanuatu's Torba province to ban Western #junkfood

    “At the moment we have an infiltration of junk food from overseas,” Fr Dini said.

    “In other provinces that have adopted western diets you see pretty young girls but when they smile they have rotten teeth, because the sugar has broken down their teeth.

    “We don’t want that to happen here and we don’t want to develop the illnesses that come with a western junk food diet.”

    The majority of Torba’s 10,000 residents are subsistence farmers, and the province thrives on locally grown fish, shellfish, taro, yams, paw paw and pineapple, The Guardian reports.

    Fr Dini has ordered the province’s tourism bungalows to start serving guests only locally grown, organic food, and he plans to pass a local law banning all foreign food within the next two years.

    He said imported rice, lollies, tinned fish and biscuits were popular imports in the province.

    “It is easy to boil noodles or rice, but they have almost no nutritional value and there is no need to eat imported food when we have so much local food grown organically on our islands,” Fr Dini said.
