Why hasn't a bridge dared to cross the Amazon River so far?
As we all know, although the Amazon River ranks second in the world, it has the widest basin area, and the size of the flow and the number of tributaries are ranked first. However, there is some controversy about the length of the Amazon River, and the more recognized of all the measurements is 6400 kilometers.
If we directly say how big the flow of the Amazon River is, it may be difficult for everyone to understand, it is better to be direct, if we add up the flow of the three major rivers of the Mississippi River, the Yangtze River and the Nile River, in fact, it is not comparable to the flow of the Amazon River. Because the flow of the Amazon River is about equal to the seven Yangtze Rivers, nearly 20% of the total flow of rivers on the earth is pocketed by the Amazon River, and the number of its tributaries is more than 15,000.
Indeed, to this day, no bridge crosses the Amazon River in all directions, although whenever the flood season comes, the Amazon River channel will accumulate floodwater, the average water is a few meters and ten meters higher than usual, and many areas will be flooded for tens or even hundreds of kilometers nearby. However, the main factor that the Amazon River does not have a bridge to cross, in addition to the difficulty of the bridge itself and environmental factors, is mainly related to the economy and the flow of people on both sides of the strait, at least so far, there is no need to spend a lot of money to build such a bridge.
Standing in the Amazon River for three minutes can take these terrible injuries:
The Amazon is the kingdom of life, with more than two thousand species of fish living here, and no continent has more than one fish species, not even the three countries owned by Mexico, the United States and Canada combined. The Amazon has long been considered a source of pride by latin Americans, with nearly 8 million square kilometers of land bursting with life thanks to its nourishment.
However, the bottom of the Amazon River is very rugged, scattered with dead trees and gravel, and some of the rapids of the water are often floating trunks. Therefore, even scientists who specialize in research must be very careful when working, and avoiding various obstacles in the water is the first task. Moreover, in the Amazon River, there are not only all kinds of strange fish animals, but also many aquatic mammals, such as freshwater dolphins and manatees, which are not rare animals.
At the same time, in the Amazon River, there is also a kind of alligator Caiman, which is about 1 to 4 meters in size and is related to the alligator, and is an amphibian carnivore, although its bite force is not as strong as the crocodile of the same size, but the average person is not necessarily their opponent. For the researchers who go to the special visit, it should not be a problem for them to spend three minutes safely in the river, after all, they know the geographical characteristics of the Amazon River and the living species, but it is difficult for ordinary people to say, and what kind of damage they may suffer depends on resilience and luck.
It grows in the Amazon rainforest of the Amazon River Basin
The Amazon rainforest, which spans 9 countries, can be said to be known to everyone, and it grows in the Amazon River Basin. Half of the entire rainforest on Earth is occupied by it, so it is the largest rainforest in the world and is known as the green heart of the earth. Although the Amazon rainforest is far away from us, its presence is important to all living things in the world.
Greenhouse gases such as carbon dioxide are known to have a serious impact on the climate, but tropical rainforests are a disaster for carbon dioxide, and the Amazon rainforest produces as much oxygen as one-tenth of the world's total oxygen. At the same time, the number of biological species in the rainforest accounts for one-fifth of the number of living species, and half of the bird and plant species on the planet live here.
However, the Amazon rainforest has also suffered severe damage in recent years, and statistics show that the rate of destruction of the rainforest once reached every 8 seconds, and then it disappeared a forest area the size of a football field. It is undeniable that the impact of human activities on the earth's environment is really large, just as the improper open use of the Amazon rainforest, coupled with the lack of local protection measures, has now dropped from the initial 80% to about 58% later.
