“Biggest analysis to date reveals huge footprint of livestock – it provides just 18% of calories but takes up 83% of farmland”

Further data on the impact of animal farming in terms of climate impacts. Lots of key points – I’ll highlight just a few here. There seem to be lots of other articles covering the same study, if you want to read further. 🙂
Leaves me wondering – if this kind of data had been available 30-50 years ago, how might that have changed how many of us grew up viewing food? When I was younger, I never specifically thought that I would end up plant-based, but I also never had this kind of data available to add into the assessment. Once I became more aware of the environmental implications, I made adjustments accordingly. So, what kinds of ways can be found to help people get excited about plant-based eating? How might this kind of data help drive positive change? How quickly might things change? Will things reach a tipping point at some time in the future? I have noticed a definite shift in the last 5 years, but there is a long ways to go. 🙂
The scientists also found that even the very lowest impact meat and dairy products still cause much more environmental harm than the least sustainable vegetable and cereal growing.
The study, published in the journal Science, created a huge dataset based on almost 40,000 farms in 119 countries and covering 40 food products that represent 90% of all that is eaten. It assessed the full impact of these foods, from farm to fork, on land use, climate change emissions, freshwater use and water pollution (eutrophication) and air pollution (acidification).
Prof Tim Benton, at the University of Leeds, UK, said: “This is an immensely useful study. It brings together a huge amount of data and that makes its conclusions much more robust. The way we produce food, consume and waste food is unsustainable from a planetary perspective. Given the global obesity crisis, changing diets – eating less livestock produce and more vegetables and fruit – has the potential to make both us and the planet healthier.”
