Humans are filling the atmosphere with more and more pollution. How does it get out of the air and where does it go? For complex pollutants in the atmosphere, having a bit of hydroxide around helps break it down but where does it come from? Hydroxide can spontaneously generate in droplets but it doesn't seem to need sunlight's or photo-chemistry. Spontaneous generation of hydroxide in water droplets helps clean up our atmosphere. Which trees are best at cleaning up the air around them? From conifers to broad leave trees which help keep our air clean the best? C is for conifer, and their leaves and needles help capture pollution out of the air. Broadleaf trees are well...broad and this helps them capture lots of air pollution.
