this is re food, and grading is from nature-aligned (A) to harmful (F) with examples of each grade given
there may be some parallel to A ranking for environmental protection groups blog. Also this news category is a good supplement.
in my personal food growing/obtaining efforts, I have been and hope to be around a (B) (sometimes (A), sometimes (C)). Of course when supporting the food system most of us are supporting, then I/we even drop to (D) & (F).
in today's world, where there is an overwhelming presence/impact from (D) & (F), it makes it very very difficult for more people to get a higher grade without adequate support
A - what is "pest"? no pests! - with most inclusive, right understanding of (the laws of) Nature, homeostasis/balance, there are no "pests." Indigenous/natives in a nature-based way of life doing hunting and gathering would likely be unaware of even the concept of "pest"
B - pests, oh well, whatever - with a less nature-aligned way of life (including in food growing/obtaining like agriculture can be seen as), there is recognition of "pests" that are undesirable to the initial human-interventions of nature (especially seen in more controlled agriculture) to obtain food, yet the pests are not considered to have to get rid of and accepted as part of the reap
C - around Integrated Pest Management approach - enlightened relative to the status quo of (F) & (D) below, more balanced, ecological IPM strategies are used. These tend to be prevention-oriented, more natural, and using chemicals as a last resort.
D - legit, profitable agribusiness as usual - realizing the incorrect ways in (F), but also needing to maintain profitability in agribusiness operations, attempts to use better, less toxic/allowable pesticides are used while maintaining too-commercial agricultural operations with pervailing competitive market pressures
F - humans are the pest - in (deep) ignorance or human supremacist ways, war-like and grossly non-ecological and highly unsustainable yet in profitable fashion, humans grow food that require the use of very harmful/banned pesticides
