Polycyclic aromatic hydrocarbons, andother kinds of heavy metal. 

Everyone has a weapon.

In this video game where we attack humans, we never lose.

Stage one: the nostril 

Your nasal hair and mucus can keep out foreign bodies.

90% of micro particles with dimensions greater than 10 microns die here.

But they can't stop me.

Stage 2 the throat (snort)

Cilium of the upper respiratory tract destroy large particulate matter in a flash,

But my body is slim and graceful.

Your trachea involuntarily contracts trying to stop me 

How embarrassing!

Stage 3: the lower respiratory tract 

It is like a tree growing upside down in here 

We zoom through the bronchial tubes like it's a downhill course

All along the way we fight hand to hand with white blood cells and lymphocytes in a free for all 

Inciting every imaginable type of inflammation

Most of our squad eventually reaches the pulmonary alveolus. 

You have more than 300 million of them

Once we get in there it is impossible to catch your breath 

But here we meet the macrophages, our most powerful adversaries.

They love to gobble us up and are known as the body’s street sweepers 

It’s an all-out battle! 

But we are too many and, we are protected by the toxins of the heavy metals 

The macrophages can't digest us and are easily defeated 

This is how we destroy your immunity 

We have another group of warriors smaller than 0.5 microns in diameter 

They can pass through the membrane of the pulmonary alveolus and plants themselves into the bloodstream, causing damage to the blood vessels inner membrane 

The vessels narrows which causes high blood pressure and blood clots 

We can even pass through your circulatory system until we arrive at its most vital organ 

And launch and offensive attack against your heart 

We can cause coronary disease and irregular heartbeat and finally a heart attack 

Tremble humans 

For I am in 

Your every breath

We keep hearing that Nepal is a developing country, and environmental protection is a luxury not afforded to us, but more often than not, those most affected by pollution are the poorest. They are most likely to be harmed. They are in most need of having a voice. They are in most need of help.
