Per person, $5 initially and $0.25 per year.&lt;p&gt;That seems incredibly cheap for the benefits. Colombia looks to have a GDP per capita about 1&amp;#x2F;10th of the US, so if we scale it up 10X...&lt;p&gt;I live in a relatively cold climate, and I would still be delighted to pay $2.50 a year for this kind of infrastructure development. Heck, even scaling it up 100X seems like it would be worth considering.&lt;p&gt;Maybe there&amp;#x27;s a cost I&amp;#x27;m missing here, but for a hot city, the AC savings alone seem like they would be worth it, not to mention the 40% reduction in respiratory infections through increased air quality.</text><parent_chain></parent_chain></comment><story><title>Medellín&apos;s Green Corridors</title><url>https://reasonstobecheerful.world/green-corridors-medellin-colombia-urban-heat/</url></story>

There are some amazing, modern, clean and green parts of the city. The botanic gardens (Jardín Botánico de Medellín) are beautiful and considerably cooler than the surrounding parts of town. The metro - with cable cars linking off to the hillside neighborhoods - is very clean, modern, and efficient.&lt;p&gt;We saw the city hall vertical garden - pretty neat.&lt;p&gt;An immense amount of effort has gone into revitalizing the city in recent years.&lt;p&gt;One thing that struck me though, is that the rising tide hasn&amp;#x27;t quite lifted all boats - or people to be more precise. I saw a lot more beggars, people living on the streets, and homeless encampments than in Bogotá, or Cali or other cities. It feels like a disconnection from community and family that is still present in other places - especially smaller cities and towns. I hope they can figure out ways to help the bottom 1%.
