according to the german environment agency wood stoves account for 20 percent of the particulate matter emitted in the pm $2.00 size range in germany that figure is rising. power plants are still the biggest emitters with 26 percent 2 thirds of these emissions stem from coal fired power plants traffic takes 3rd place with 19 percent of the share contributed by agriculture is just 5 percent. but the german environment agency only measures direct emissions your slowly felt is a professor of atmospheric physics at the max planck institute for chemistry his findings are quite different lady fell says there's another culprit responsible for polluted air livestock. yeah. the animals bear a share of responsibility for the problem this from a great sustainably but whenever you buy cheap meat from a conventional factory farm you're making a decisive contribution to the creation of atmospheric particulates matter. how was that possible layfield explains the following distinction primary particulate matter is emitted directly into the atmosphere when matter created for example by tie aware of or e

i believe the german environment agencies figure of 5 percent is too low. or 70 percent of find particulate matter is formed in the atmosphere it isn't released in some way as dust is formed chemically. making a point here and been livestock manure is spread as fertilizer in the fields and the ammonia it contains escapes into the atmosphere only or so escapes from the stables and particulate matter is formed when ammonia combines with nitrogen oxides from road traffic if i stop being. laid felt alarming conclusion some 40 percent of all the fine particulate matter in germany is generated by agriculture and above all by factory farming. omonia gas from farm in your blankets the ground and reacts among other things with nitrogen oxides from traffic to form ammonium nitrate in the atmosphere it may be carcinogenic high omonia levels are produced in northwestern germany a center of industrial animal farming west winds carry the gas across the country meat production is a key industry in germany could that be why there's so little public debate about agriculture
