This submission takes on a novel "square zero" approach to the idea of
we can't create effective green space unless both the public and businesses understand the dire need for their creation.
Aside from the negative impact on the mental and physical health of citizens, one of the top consequences of lack of green space is increased particle pollution. As particle pollution isn't usually visible to humans, it's easy to pretend that it doesn't exist, and therefore, enables citizens to ignore the problem or be less inclined to support public policy initiatives to create more green space.
Information via epa.gov:
O3: Ozone is both natural and man-made and has both beneficial and adverse affects on human health. In the atmosphere, it shields humans from harmful UV exposure, but when inhaled, it undergoes dangerous chemical reactions with molecules in the respiratory tract.
SO2: sulfur dioxide is primarily emitted through fossil fuel combustion. Increased sulfur dioxide concentration leads to increase particulate matter (PM) pollution.
PM2.5: PM2.5 refers to a class of ultra-fine particulate pollutants, with diameters under 2.5 micrometers.
PM10: PM10 refers to a class of ultra-fine particulate pollutants, with diameters under 10 micrometers.
NH3: Ammonia is a toxicant that typically arises from waste. Large amounts of ammonia can lead to decreased respiratory function, reduction of Na+ to potentially fatal levels, and disruption of blood vessels.
Cities with the most green spaces strongly overlap with cities with lowest particle pollution (data from tpl.org):
both of these cities top global green space statistics, with close to or over 50% of parks and gardens being public green space.
both of these cities have less than 2% public green space, and much higher pollution rates than Singapore and Zurich, despite having lower population densities than Singapore and Zurich, respectively.
