The population of the world is growing at an alarming pace.
Countries like India and China have populations in the billions, which must be fed.
This might not seem like everyone's problem, but in reality it is.
Just like dominoes, hunger in one country does affect the situation in another.
This is especially true when the country in trouble has a larger population.
This challenge is nothing more than the outcome of supply and demand.
When a larger country that becomes in desperate need of some necessity, it has to turn to the market for purchase.
This in return increases the demand of that product, which raises its price.
We have seen this happen in the past.
Just recently, the demand for rice went up when supply went down.
This resulted prices for rice to sky rocket, which made it even more difficult for less developed countries.
As a reaction, this resulted in both hunger and riots.
How does a pulse oximeter relate to world hunger? The answer to this question is based on the idea that if you constantly work on meeting the demands of the market, you can control its inflation.
In other words, if you give the people what they want at the price they want it; it benefits both the supplier and the consumer.
The consumer wins because they get their needs fulfilled, while the supplier makes more money by selling in volume.
In the past, a pulse oximeter was sold in limited numbers at high prices.
Now with the advances in technology and software, a pulse oximeter is available to the masses for less than one hundred dollars.
A pulse oximeter, also known as a pulse ox by some medical professionals, is a medical device used to measure blood oxygen saturation and pulse rate of an individual.
A pulse oximeter might not solve world hunger, but it has learned a lot from it.
