Agreed with most of your material here. Be careful with that Wedderburn-Bisshop article. It is a bit deceptive and I am not sure the conclusion is fully justified. Animal agriculture is responsible for a lot of climate problems, but mainly because it directly or indirectly uses a lot of fossil fuels. We feed the animals corns and soybeans, very destructive of soils and SOM, and the nitrogen fertilizer used all comes from methane for energy and as a hydrogen source. It leaks. Everything in the animal agriculture system is powered by fossil energy. So blame it, but recognize that it cannot exist without the fossil fuels driving it. Overall, I fully agree with you on the internet and its impact, as well as the impact of chemicals on life. We use none and my insect population is healthy, especially colonies of ground nesting bees and bumblebees.

Be sure to scroll through the whole Wedderburn-Bisshop article, Wayne. https://iopscience.iop.org/article/10.1088/1748-9326/adb7f2/pdf They level the playing field when calculating climate impact from total equivalent forcings. They account for the aerosol effect from fossil and industrial pollutants quite well, going back to the 18th century. I think one could go back even farther, say 12000 years, and likely find an even larger contribution proportion attributable to land use change for farming, domestication of animals, and loss of megafauna populations that maintained a carbon balance, such as mammoths and whales.
