Code Orange for Ground Level Ozone

 Received this email alert today on Air Quality. Thought I had left behind all the Air Quality Alerts in CA from the yearly wildfire smoke. 

"Air Quality Alert.... Tennessee Department of Environment and Conservation has issued a Code Orange Health Advisory for the Nashville Area... Ground Level Ozone concentrations may approach unhealthy levels... active children and adults and people with respiratory issues ... should limit prolonged outdoor exertion."

So what exactly is Ground Level Ozone (also often referred to as "bad" ozone).  

This is ozone that is not emitted directly into the air like some other pollutants. Instead, it forms in the atmosphere through a chemical reaction involving precursor pollutants in the presence of sunlight. Here is how it happens: 

1. Emission of Precursor Pollutants: The primary precursor pollutants for ground-level ozone are nitrogen oxides (NOx) and volatile organic compounds (VOCs). These pollutants are released into the air from various sources, including vehicles (especially those with internal combustion engines), industrial processes, and natural sources like vegetation

2. Chemical Reactions: Once in the atmosphere, NOx and VOCs undergo a series of complex chemical reactions in the presence of sunlight. This process is known as photochemical smog formation. Sunlight provides the energy needed to break down these precursor pollutants and form ground-level ozone

3. Ozone Formation: The chemical reactions between NOx and VOCs produce ground-level ozone (O3) and other secondary pollutants. Ground-level ozone is a key component of smog and is harmful to human health when present in high concentrations near the Earth's surface.


And what is Code Orange
Code Orange: This level signifies that air quality is unhealthy for sensitive groups which include active children and adults, as well as individuals with respiratory diseases such as asthma.

The weather is absurd

The weather is truly absurd,
Can't decide. That's the Word!
Snow flurries on Saturday
Spring equinox the next day. 
Two days later, summer hot 
80 F? seriously, what have we got?
Now its pouring rain again
The weather is going insane

Commodifying Nature

I like waterfalls, so many of our vacations end going to places with waterfalls which basically takes us to national parks. There is a trail in oregon where you can see 11 waterfalls.

And national parks give you easier access by building roads right unto them. Its a pity because they are actually making it less natural by building all the roads like in Yosemite.

I feel we have commodified and compartmentalized nature. nature is catered to tourists who have money to spend and cut off from the marginalized bodies and the poor. I want to touch things and maybe obsess over little things like the water tricking over one specific rock.
