Really all they eventually say is eat less dairy and meat. As in industrial meat and dairy farming impact the environment more that vegetable crops.
Nothing else to take away from it. Pretty much a pointless "well duh" article with an end comment that we need to do less travel by road and air. Well that will never happen and another pandemic will force more on the roads separately instead of sharing bus, train, or plane. However BEV will pretty much solve the majority of the pollution side but it will increase miles traveled.
