One of the other costs of fossil fuels that isnt. mentioned as. much is the resultant pollution and environmental degradation. These externalities are real. Due to the air pollution that gets trapped in the LA basin, Los Angeles has the worst air pollution in the US. 1300 lives are cu5 short each year due to the smog and over the course of a lifetime, breathing the air will shorten your lifespan by a few years.[1]. Also, air pollution is thought to double the risk of dementia in women according to a recent study. [2]

Another grave consequence of bith global climate change and localized pollution is the loss of biodiversity and the chance to study and learn from other organisms and their unique genomes and adaptations.
