What is water pollution? Water pollution is a source of water contaminated with chemicals or foreign substances that are detrimental to human, plant or animal health. It occurs when harmful substances get into bodies of water such as lakes, rivers, oceans, etc., which can be dissolved, suspended or deposited in the water. At that time, it greatly affects the environment and organisms around the world.
Therefore, we need to have the right measures to overcome water pollution. Firstly, there must be severe and severe sanctions against individuals, organizations and agencies that commit acts of destroying the environment, affecting people's lives. In addition, it is also necessary to educate the people through propaganda and encouragement such as organizing exchanges to discuss environmental issues at the ward and commune level administrative units ... More detailed articles about the environment in textbooks right from the elementary level, helping students to have the right attitude and view about the environment and its consequences, thereby helping them to know love and protect the environment in which I live. Another way to help protect the environment is to launch volunteer movements more often such as environmental protection in residential areas, garbage collection in public areas, and beach cleaning ...
We need to join hands to protect the environment and avoid pollution for the future of a green, clean, beautiful Vietnam, and for our own life as well as for generations to come! Let's protect the environment to protect our own lives.

An: Hello Manh , What are you doing ?
Manh : Oh , Hi An . I'm reading a magazine about tsunami .
An : What is tsunami ?
Manh : Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. The speed of tsunami waves depends on ocean depth rather than the distance from the source of the wave. Tsunami waves may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters. While tsunamis are often referred to as tidal waves, this name is discouraged by oceanographers because tides have little to do with these giant waves.
An : It sounds terrible .What is it cause ?
Manh: First , it causes many deaths . Since 1850 alone, tsunamis have been responsible for the loss of more than 430,000 lives. Second , the amount of energy and water contained in a huge tsunami can cause extreme destruction when it strikes land. And finally Tsunamis not only destroy human life, but have a devastating effect on insects, animals, plants, and natural resources. A tsunami changes the landscape. It uproots trees and plants and destroys animal habitats such as nesting sites for birds. Land animals are killed by drowning and sea animals are killed by pollution if dangerous chemicals are washed away into the sea, thus poisoning the marine life.
An : How can we to stop it ?
Manh : From my point of view, we need many factors to simulate Tsunami wave than we can find solution for this problem. One of this factor as Gobo A.E. mentioned above, also we need to know how many cycle per each period for example 10 years that happened and also the height of the wave when it attach the land. When we study deeply all factors then we can find solution such as we can made some gates in front of the coast lying horizontal in water when the level of water increase more then the normal this gate change its position to the vertical to crash the wave height and to reduce the damage on the land behind it.
An : That's true.
