The Aswan High Dam was built to regulate and control the annual flooding of the Nile River in order to protect crops and property from such uncontrolled flooding and to generate electricity. Most of its effects have been positive but several environmental effects are:
- Water-logging: because of the continuous high levels of water, the soil around the area is saturated with water, which prevents oxygenation of the soil that is essential to several plants and crops.
- Salinization of soils: caused by the inability of water-saturated soils to absorb salt, it is toxic to crops and damaging to infrastructures.
- Soil Erosion: it is a consequence of soil salinization as crops die and are unable to hold the soil in place.
There were also other negative effects such as:
- Archeology: two important archeological sites of Ancient Egypt were flooded and covered by the dam waters: the ancient cemetery of Fadrus and the Buhen fort.
- Loss of sediment: the annual flooding carried an enormous amount of sediment that is now trapped within the resulting Lake Nasser. Many of these sediments were used by local industries to manufacture bricks and they lost access to this renewable source of raw materials.
- More expensive and difficult purification of water: because the water does not move as much it is more transparent and allows the sunlight to penetrate deeper. This, combined with the trapped sediments has increased the growth of algae that have proliferated to the point that water purification is more and more expensive due to the necessary removal of this plant.

The difference between South Africa and Vietnam revolutions was:
A. The Vietnamese fought for independence, while South Africans fought for race equality after winning independence.
When WWII finished, the Japanese forces in the north of Vietnam were to surrender to the Chinese and in the south to the British armies. During this process Chi Minh and the Viet Minh rouse to fight for Vietnam independece, declared in the 14th of August. This is known as the August Revolution.

If we refer to the time period of American civil war and slavery period. In the United States, lynching took place before and after those time periods. In 19th century to be more specific. Lynching was performed to people considered inferior and with no rights at that time as African Americans, Mexicans Asian immigrants and so forth.
Usually, it would be perform commonly by hanging, ended up continuous in the South amid the period after the Reconstruction time and particularly amid the decades on either side of the turn of the twentieth century. At the time, Southern states were passing new constitutions and laws to disappoint African Americans and force lawful isolation and Jim Crow rule. Most lynchings were directed by white hordes against black exploited people, frequently speculates taken from prison before they were attempted by every single white jury, or even before capture. Lynchings were captured and distributed as postcards, to extend the terrorizing of the acts. Victims were now and again shot, consumed alive, or generally tormented and ravaged in the general population events. So the items white public brought were: axes, ropes, whips, torches, hooks, and spears to contribute on this terrible masses act.
