Today I went to the library (a different library than my previous thread) to watch a conference about the digital billboards in the city: their effects on human health and biodiversity, the existing laws regulating their use, whether those laws are being enforced, and the political challenges involved. It was organized by an NGO that has been keeping track of environmental hazards in the city for years.
