GP isn't blaming humans for animal diseases, but I am. Human trade spreads pathogens/diseases at a tremendous rate compared to natural diffusion. There's quite a long list of diseases in non-humans spread through human trade. Human activity might also make animals more susceptible to disease in general through a weakening of overall health through pollution and environmental disruption. This effect is hard to quantify but has the potential to be quite large.
