All products that you find in stores and outlets all over the country and even the world at large had to go through a thorough process of screening to seek approval before they can be put up for sale to citizens of the country. The government has put agencies in place to make sure everything that is put up for human consumption is healthy.
One amazing thing is that there is also a similar law and a similar agency that tests the quality of air that humans breathe in. There is a scale that is used to measure the quality of good air, and it is called the Air Quality Index (AQI). It is more interesting to find out that the test had been in existence since the year 1968, and it had been working for its purpose for a long time.
Usually ratings like this are measured good by how high the score is, but on the AQI, a good result is determined by how low the score it. The air is considered to be toxic if it is rated anything above 150, and a state of emergency has to be declared. However, when you have a score below 50, we’re good. A bad rating would mean that there could be an epidemic if people continue to breathe the bad air in.
One of the cities with the highest ratings on the AQI is Bangkok. In Thailand, Bangkok is the most populated city, and it is also one of the most crowded places in the world. Usually, Bangkok records one of the highest AQI scores in the world, and it happens very frequently. The score was consistently above 200 in the city such that the government had to find something to do fix their hair issues. The kind of hair in Bangkok is dense and humid, so it keeps toxic pollutants around for a little more time than it should be around.
The government decided that the way out is to create more rain artificially.
The government created an agency called the Thailand’s Department of Royal Rainmaking and Agricultural Aviation. They referred back to a technology created in 1946 by a chemist in America called Vincent Schaefer. This technology is called Cloud-seeding. The technique used molecules of silver iodide to stimulate the clouds. So when more molecules are released, more rain is to be expected.
Since they started using this technique, more rain has been falling and the AQI has registered lower scores every since. Hopefully, this technique will not have a negative impact on the things it is falling on because it has been tested to be a little impure.
