The rivers Rivers are constantly moving bodies of water that play a crucial role in life on the planet. These freshwater currents are not only home to thousands of species, but they also maintain entire ecosystems, serve as a source of drinking water, generate electricity, and provide fertile soil for agriculture. Their importance to rainforests and forests is irreplaceable. The world is home to a vast number of rivers, but when we talk about their size, the most common question is, What is the longest river in the world?For a long time, the debate has oscillated between two giants: the Amazon River and the Nile riverHowever, the debate is still open today, giving rise to important studies and explorations. Until 2008, the answer was clear to many, but new discoveries have shaken that knowledge.
What is the longest river in the world: the Nile or the Amazon?
One of the rivers that has been at the center of this debate is the Nile river, located in Africa. This imposing river has been fundamental in the development of civilizations as important as that of Ancient Egypt. Throughout its 6.756 km, the Nile flows through several countries, including Uganda, Kenya, Tanzania, Rwanda, Burundi, Ethiopia, South Sudan, Sudan and Egypt, finally leading to the Mediterranean SeaIn the past, this river was essential for transportation and trade, and it remains central to the culture and livelihood of the surrounding region. However, in 2008, a group of scientists suggested that the Amazon, in South America, is actually longer. For a long time, its length was thought to be about 6.400 km, but new measurements raise that figure to 7.062 kmThus surpassing the Nile. The previous error stemmed from the incorrect location of the Amazon’s source, which until then was believed to be in northern Peru. Through extensive studies and more recent explorations, it has been determined that the river actually originates further south, in the Peruvian Andes mountain range, adding to its length. The Amazon and Nile rivers not only compete in length; they are also important for their ecological and geopolitical impact. While the Nile provides a valuable water resource to millions of people and is key to agriculture in Northeast Africa, the Amazon nourishes the world’s largest rainforest, considered the lungs of the planet. But what else does this comparison tell us?
The Amazon, the longest and most voluminous river in the world
The Amazon is not only remarkable for its impressive length. It is also the largest river in the world. most abundant in the world, carrying more water than the Nile, Yangtze and Mississippi combined. It is estimated that, on average, the river discharges 219,000 cubic meters per second, what represents one fifth of all river water on the planet. Moreover, at its widest point, the Amazon can be up to 11 kilometers wide In the dry season, and in the rainy season, that figure can increase significantly, flooding up to 350.000 square kilometers of its basin. The river is part of the most biodiverse ecosystem on the planet, the Amazon jungle, which covers territories of Brazil, Peru, Colombia, Bolivia, Ecuador and VenezuelaIn that vast region, it is estimated that around 1,000 live 3.000 species of animalsIncluding Pink dolphins, anacondas and piranhasAmong other things, the Amazon is not only home to fascinating species, but it also provides sustenance to millions of people who depend on its resources. Furthermore, the Amazon is considered a natural wonder due to the sheer size of its basin, which covers nearly 40% of South America. From its source to its mouth in the Atlantic OceanThe river flows through a wide variety of landscapes. At the mouth of the river, ocean-going vessels can navigate up to two-thirds of the way inland, thanks to its depth and width.
Life on the Amazon River
The rich biodiversity of the Amazon is manifested in the quantity and variety of from? that inhabit its waters and on its banks. Some of the most notable species include:
Animals that live in the Amazon
- Chick spider (Theraphosidae): This species measures between 5 and 7 cm, and although it is not dangerous, its stinging hairs can cause irritation.
- electric eel (Electrophorus electricus): Capable of generating electrical discharges of up to 600 volts for defense or hunting.
- Blue macaw (Anodorhynchus hyacinthinus): A bird that, after pairing, chooses a single partner for life.
- Piracucu (Arapaima gigas): It is one of the largest fish in the world, reaching up to 3 meters.
Aquatic plants of the Amazon
In addition to the impressive diversity of animals, the Amazon is also home to a wide variety of aquatic plants such as water fern (Azolla) or the Giant water lily (Eichhornia crassipes), whose leaves can reach a diameter of up to 90 centimeters. These plants play a crucial role in the health of the aquatic ecosystem, as they help oxygenate the water and provide shelter for numerous marine species. However, they can also become a threat if their growth gets out of control, as they can cover large areas of water, blocking sunlight and disrupting the ecosystem’s balance. Many stories, both biological and cultural, flow through the Amazon, positioning it as a landmark not only in geography but also in the human imagination. Protecting this river and its basin is key to the future of the planet, not only because of its immense biodiversity but also because of its role in the global water cycle. The importance of the Amazon, and its title as the world’s longest river, cannot be underestimated. While the rivalry with the Nile continues, what is undeniable is that both rivers are giants that have shaped civilizations and the ecosystems around them.
