How Humans Have Impacted the Nile River
Transcript of How Humans Have Impacted the Nile River
By: Samantha Einhorn
The fishing industry has heavily impacted the Nile River including the introduction of the Nile perch to both the river and Lake Victoria. The introduction of the Perch is one of most terrible things that has recently happened to the water. (1)
Introduction of the Nile Perch
The meat-eating Nile Perch was introduced to the Nile River ecosystem around the mid-1900's, but the exact date is unknown. (1)
The Nile Perch originates from Lake Turkana. It was brought to the Nile mainly to enhance the fishing industry. (1)
Lake Victoria did have many fish, but the fish that lived there were tiny. They did not provide fishing industries with what was required. Therefor, the introduction of the Nile Perch seemed like it would be a great thing. (1)
Especially during the 1900's and 80' the Perch adapted to the Nile River environment, grew, and expanded. (1)
Since the Nile Perch is carnivorous, it has affected many species negatively, and as a result there have been many extinctions and population fall outs in the Nile. (1)
The Nile perch has evolved into the dominant species of the river, and is one of the reasons why the ecosystem is no longer diverse. (1)
Recently the Nile River ecosystem has been experiencing a major dwindling in the diversity of its fish and populations. (1)
The narrowing down of the Nile's and diversity threatens not only the stability of the ecosystem, but the people living around the river as well. (1)
The Nile was once diverse, and it had many different species of fish and populations In fact, it had more than 300 different variations. (1)
Despite the variety of fish, the region’s fishing industries struggled to expand because the fish that did inhabit the river and lakes were small and scrawny. The commercial fishing industry required larger fish. (1)
A more marketable fish was mandatory. This fish turned out to be the Nile Perch, but it has done more harm than help. (1)
Recently the Nile River has become very polluted. Mahmound Abu Zeid, the president of the Arab Water Council, announced, "Water is a basic right for every human being, and once we all agree that it is a basic right, we all should work to providing this basic right in a decent way. I mean better quality, good quality, good quantity and so on". Mahmound has recognized that industrial pollution and agricultural run-off threaten the health of the Nile River along with the dumping of human waste. (3)
Since the Nile River is a very urbanized region, it has resulted in industrial pollution. About 700 industrial factories are located along the river which damage the water greatly. (1)
In the water, metals mix with suspended solids that form thick sludge. (3)
Other than water pollution, industry has been connected to air pollution and is responsible for the smog covering major cities like Cairo and Alexandria. (3)
The air pollution caused by the industries is extremely wide-spread. The major cities are recognized for the smog around them.(3)
Also, growing use of chemical manures in agriculture add to the increasing of agrochemical pollutants. (3)
The increasing population grows worse due to the dumping of human wastes. (3)
Agricultural runoff including pollutants like salts, nutrients such as phosphorus, pesticide residue, and nitrogen affect the Nile. Agricultural pollutants can come from almost anywhere in a region. Also, additional runoff that seeps into groundwater can create even more problems. (3)
An estimated amount of 60% of human waste ends up in sewage systems in the cities, and less than 40% goes to rural areas. This has contributed to the reason why about 17000 children die of dysentery every year. (3)
The Nile is the world's longest river and it travels through 10 countries. It is a vital waterway to many people, but unfortunately civilization has had a negative impact on the water. (5)
Overall, people have impacted the Nile River and its ecosystem in many ways over the years. The introduction of the Nile Perch, and Pollution have really caused harm to the Nile. Unless something changes the future of the Nile River could be disastrous.
