Air Pollution Blame Game

When asked about the major contributors to air pollution (a major source of human health problems), a survey of 16000 people somewhat predictably came up with industry and vehicle emissions as being prime candidates (https://www.theguardian.com/environment/2021/jan/15/pollutionwatch-major-sources-of-air-pollution-often-overlooked). Survey respondents rarely named agriculture (where animal ammonia production, influences emissions) and home heating, as having major impacts on air quality. In fact, these last two sources of air pollution are much more important, than most people believe. Quite a lot of industrial pollution is well-regulated, in the UK, but we have hardly made any progress in limiting the impact of central heating systems from private homes on the air we breathe.
