Air Pollution

Air pollution is nothing than only a little bit drop in the quality of air. The air quality comes in a bad stage through entering the solid, liquid and gas particles. This unexpected effect in the air comes due to the arrival of oxide, hydrocarbon and other toxic gases effect. The pollution can be classified according to their occurrence that kills the natural effect. However, it is seen that many pollutants come in air with the natural resource. There is no participation of the external material. The lists of this pollutant are dust, sea salt, volcanic ashes, and gases. So, there is no need to complain about external causes only. Some of the pollutants are human-made due to achieve the short term comfort. The human and natural being has adopted this pollutant. The pollution is described as the primary and secondary pollutants. The primary pollutants are those that damage air quality and its index value directly. The best example of the primary pollutants is that made from the exhaust fumes from the car, scooter, dust storm, thunder stroke and ash from the volcanic cell eruption. Secondary pollution is made from the chemical reaction and laboratory test for checking the quality of a certain object. To stay away from this problem, there is the utilization of the standard chemical laboratory test.

A Greedy Dog and a Piece of Meat

Over the river there was a bridge. The river was full to the brim. While the dog  was passing the bridge he saw his own shadow into the water. But he thought it was another dog. The shadow dog also had a piece of meat that was his own meat. But the dog was unable to understand the matter. To have that  piece of meat the dog barked and jumped  into the river.

The teaching of the story is 'grasp all lost all'.
