I understand that neither Perkins or Salatin are primary sources but both are knowledgeable and have looked at the science.
Thank you. I was wondering if you'd seen recent research behind your comment. Perkins and Salatin get their science from Allan Savory who started the whole 'mob grazing to mimic wild herds' idea. You'll find his theories have mostly been debunked .
According to a 2016 study published by the University of Uppsala, the actual rate at which improved grazing management could contribute to carbon sequestration is
seven times lower than the claims made by Savory. The study concludes that holistic management cannot reverse climate change. A study by the Food and Climate Research Network in 2017 concluded that Savory's claims about carbon sequestration were "unrealistic" and very different from those issued by peer-reviewed studies.
HOWEVER I take your main point - I do believe food prices will continue to increase. Thank goodness we on here can grow our own. We may need to remember our neighbours with spare produce.
