The Cagayan River
1. Also known as the Rio Grande de Cagayan, it is located in the Philippines in the Cagayan Valley region in the northeastern part of Luzon Island. It traverses the provinces of Nueva Vizcaya, Quirino, Isabela and Cagayan.
2. The Cagayan River is used for

draining fertile valleys that produces a variety of crops including rice, corn, bananas, coconut, citrus and tobacco. There are several mining concessions in the mineral-rich Cordillera Mountains near the headwaters of the river. Provincial governments along the river have also developed tourism programs that offer activities on the river like whitewater rafting.

The Douro River

1) The Douro River is one of the major rivers of the Iberian Peninsula, flowing from its source near Duruelo de la Sierra in Soria Province across northern-central Spain and Portugal to its outlet at Porto.

2) The Douro River is used for irrigation to grow olives, almonds, and grapes to make famous port wine.

3) I would not drink from the Douro River because a significant number of samples testing for dissolved oxygen presented levels below 5.0 mg. all the other parameters measured fell well within acceptable limits. Occasional high levels were found for most trace elements, reflecting sporadic and local inputs. There are also lots of boat cruises that go through the river creating pollution.

4) In the Douro River, metals such as (Al, Fe, Cu, Pb, Cr, Ni, Cd, Zn and Mn) have also been found.  Anthropogenic metal contamination was identified at the north bank of the Douro estuary, with deleterious effects on the macrobenthic community, namely decrease in number of species and diversity. This contamination could possibly also be toxic for water column organisms.

5) The metals got into the water through urban agriculture, burning fossil fuels, also human respiration and decay. The Douro River is also used for a lot of boat tours/cruises.

Nile river

1. The Nile river runs south from the Mediterranean Sea into Egypt and threw Uganda in north Africa. Its one of the largest and most well known rivers around the world.
2. The Nile's water is used to irrigate crops, feed people and for medical uses. The soil is extremely rich and fertile so that is used as well for farming crops.
3. Yes but only if it is boiled for safety and made clean just in case because Egypt is very low on water because it is a very hot and desert like place. This means the Nile is a major source of water from them so it is used a lot. the water is mineral rich too. It is slowly becoming more polluted every year do to things such as industrial waste water or other pollutants.
4. elements in the Nile Rivers water include industrial waste water that could contain all kinds of chemicals and oils. It has also been damaged by agricultural drainage which took away a lot of the water the river had before.
5. It got this way because of industrial business such as construction, cosmetic making and developing other things that could have toxins and chemicals. oil has been spilled in the river and has been drained so much for people to use the water that it has shrank from its original size. There is also a serious air pollution problem in Egypt that makes it worse.

Rio de la Plata
1. Rio de la Plata or River of Silver, is located between the South American countries Argentina and Uruguay.
2. The economic usefulness of these river systems is not commensurate with the area that they drain. Economic uses to which these rivers might lend themselves, such as irrigation or hydroelectric power, are difficult to achieve. The swamps of the Pantanal and the Chaco long made agriculture a virtual impossibility in these areas. The economic development of the upper basin has been hindered by limited natural resources. Paraguay and adjacent parts of Brazil and Argentina are virtually devoid of mineral deposits. Industry, therefore, is limited to processing agricultural products
3. I would not drink from the Rio de la Plata because the river neglects natural resources. The river has lots of chemicals that pollute the water as seen below. The river also has an abundance of boat traffic causing fuels to pollute the water.
4. Even though a large number of people are dependent on the waters of the Rio de la Plata and its rivers for their domestic water consumption, the pollution of these same waters from industrial wastes and sewage, as well as pesticide and fertilizer run-offs from agricultural lands, has led to a sharp decline in the water quality.
5. The coasts of the Río de la Plata are the most densely populated areas of Argentina (Buenos Aires) and Uruguay (Montevideo). Due to pollution from these areas and the abundance of river sediment, the river is usually a brown color. Fortunately there are currently several efforts underway to restore the river and protect its unique wildlife.

5. Description

The Rio de la Plata is a funnel-shaped estuary formed by the confluence of the Uruguay and the Paraná rivers on the east coast of South America . The waters of the estuary drain into the Atlantic Ocean. The head of the Rio de la Plata is comprised by the delta of the Paraná River and the mouth of the Uruguay. The estuary extends for a distance of 290 kilometers, widening out with decreasing distance from the sea, ranging from being about 2 kilometers wide near its source to nearly 220 kilometers wide near its mouth. The Rio de la Plata forms a natural border between the South American countries of Uruguay and Argentina, and the surrounding lands are some of the most densely populated areas for each of these countries. Many significant port cities of Argentina and Uruguay, as well as their respective capital cities of Buenos Aires and Montevideo, are located along this estuary.

4. Historical Role

Prior to the arrival of Europeans, the land in and around the Rio de la Plata area was occupied by the indigenous people of South America. The first detailed exploration of this estuary was carried out by Spanish and Portuguese explorers in the 16th Century. Sebastian Cabot was the first to create a detailed map of the Rio de la Plata region, doing so after navigating through the estuary for trade purposes between the years 1526 and 1529. With the introduction of modern agricultural methods and expansions of trade along the estuary, soon human settlements were better allowed to flourish along the banks of the Rio de la Plata. With the end of European colonial rule in the region, several of the newly formed independent South American countries focused their attention towards the control of the promising land around the Rio de la Plata for themselves. The Argentine Civil War, the Cisplatine War, the Platine War, the Paraguayan War, and the Chaco War were all fought between South American countries with a focus on controlling the abundant natural resources present in and around the Rio de la Plata.

3. Modern Significance

The Rio de la Plata region is currently home to some of the most densely inhabited regions of both Argentina and Uruguay. Nearly 70% of Uruguay's population lives close to this region. South America's largest port and Argentina's capital city, Buenos Aires, lies on the western banks of the estuary, and 96% of the country's coastal traffic is handled by this single port city alone. Large volumes of Argentine and Uruguayan meat and cereal exports are handled by the ports located along the Rio de la Plata. The industries required for processing such export products are also built along the banks of this estuary. The nature reserve of Reserva Ecológica Constanera Sur, just east of Buenos Aires, is a tourist hot-spot as well. This unique wetland ecosystem, with its wide range of flora and fauna, attracts tourists from all over the world. Over 500 species of birds can be spotted in this protected region.

2. Habitat

The Rio de la Plata supports a wide variety of plant and animal life. The Upper Paraná river zone, to the east of the Rio de la Plata, supports the growth of forests rich in such evergreen trees las the Paraná Pine. The lower reaches of the Paraná Basin is mainly comprised by vast tracts of grasslands, after mostly being cleared of trees for animal grazing and crop cultivation. The Paraná River Delta and the estuary region of the Rio de la Plata support typical flora of a South American wetland ecosystem, like the water hyacinth, the Amazon water lily, and guama, just to name a few. Some important animal species of the Rio de la Plata ecosystems include the rare and "vulnerable" La Plata dolphin, jaguars, tapirs, and ocelots, along with several species of the Rio de la Plata's turtles, which include the likes of the "vulnerable" Loggerhead sea turtle and Leather-back sea turtle, and the "endangered" Green sea turtle. Besides turtles, other reptiles such as the caiman, rattlesnakes, iguanas, and Cross vipers, as well as a number of amphibian species, also thrive in the Rio de la Plata region. 350 fish species, of which 85 are endemic, are found in the La Plata Basin as well. These include such fish as the carnivorous piranha, the pacu, the Dorado, catfishes, and the manduva, all of which are abundant in the waters of the estuary. Nearly 650 species of birds nest in this region as well, including a variety of parrots, eagles, and kites.

1. Threats and Disputes

Even though a large number of people are dependent on the waters of the Rio de la Plata and its rivers for their domestic water consumption, the pollution of these same waters from industrial wastes and sewage, as well as pesticide and fertilizer run-offs from agricultural lands, has led to a sharp decline in the water quality here. Large scale deforestation of land, and the use of mechanized agricultural practices, along the course of the Uruguay and Paraná Rivers has triggered soil erosion and sedimentation throughout the Rio de la Plata Region. Introduction of non-native species from Asia and Africa, like golden mussels, into the waters of the Rio de la Plata by ships harboring these species in their hulls, chains, and keel further threatens to replace the native aquatic flora of the wetland ecosystem. Such invasive secies are disturbing the food chain, and thus displacing the native species of the region and their ecological roles.

Zambezi River
1. The Zambezi River is the fourth longest river in Africa and the longest east flowing river in Africa. It flows through six countries on its way from its source in north western part of Zambia to the Indian Ocean.
2. The river is home to about 40 million people who rely on the river for drinking water, fisheries, irrigation, hydropower production, mining and industry, ecosystem maintenance, and other uses.
3. I probably wouldn't drink from this water, because of the many things it's used for.
4.  The water pollution from the fisheries, hydropower production, mining and industry, and ecosystem maintenance has led to the containing of unsafe and undrinkable water.
5. The water got this from the multiple people in Zambezi using the water, animals, bacteria, and the other factors listed above.

Orinoco River

1. The Orinoco River is a major river flowing through South America in which starts in the Guiana Highlands and opens into the Atlantic Ocean through a marshy delta. It flows in a wide arc through rainforests and savannas (Ilanos). This river creates a frontier between Venezuela and Columbia as it is around 1, 600 miles long. This river is known for it's ability to navigate easily. It is one of longest rivers in South America.
2. This river is mainly used as a route for transportation as it passes through forests that would be difficult for humans to pass through otherwise. Plus, it is easy to navigate most of the way. The Piaroa people use this water source to grow vegetables and catch fish for food.
3. No,  because this water is mainly used for fishing, growing food, and transportation purposes, not drinking. There is so much pollution and debris from mines nearby that the water is not purified to drink. The people living along this river do not drink it because it is not filtered, so usually they have to get their water brought into them by trucks from the government.
4. There is a lot of bacteria, dirt, weeds, dangerous animals, and mineral deposits from mining, including iron ore and vanadium, are all found inside which makes it dangerous to drink. Plus, Venezuela does not have enough money to filtrate the water for this river so now it is used for transportation.
5. There are many mines around the outline of the river that cause pollution and mineral deposits to contaminate the water. It also runs near major cities in Venezuela, so there is pollution around those parts also.

2.) The water of the Yangtze is used for a dividing line between North and South China. The River is historically, culturally, and economically important to the country.
3.) I would not drink the water from the Yangtze River, because the water lacks natural resources. Countries surrounding the water do not find it suitable for drinking either.
4.) The pollution from the Three Gorges Dam has led to making the water very unclean and unsuitable for drinking.
5.) The water had become dirty from the dam, and large scale industrial and domestic development. Agricultural runoff also led to the water becoming unsanitary.
