The Mystery of the Amazon
The Mystery of the Amazon
Located in South America, the Amazon is the largest forest in the world. The Amazon River is the lifeblood of the Amazon Forest. The Great Amazon covers an area of 7 million square kilometers in about nine countries. In terms of size, Amazon is 36 times bigger than Bangladesh. The Amazon is half the amount of rainforest in the world. There are about 39 billion trees of 40,000 species in this forest. The Amazon forest produces 20% of the world's oxygen.
That is why it is called the lungs of the earth. The Amazon forest was created about 50 million years ago in the Eocene era. The emergence of warm and humid climates in the Amazon Basin at that time created the Amazon Forest. The Amazon rainforest covers most of South America. Out of the total area of 60 lakh sq km of this forest, 55 lakh sq km is affected by humid climate. Just as Sundarbans is located between two countries, Bangladesh and India, Amazon is located between 9 countries.
Of these nine countries, 60 percent of the Amazon is in Brazil alone. The remaining 13 percent is in Peru, 10 percent in Colombia and 17 percent in the remaining six (Polygia, Ecuador, Benizlia. Cayana, French Cayana, Suriname) countries.
The animals and plants of the Amazon are as diverse as the size of this forest. Biodiversity The Amazon forest is home to some 40,000 species of trees, 1,300 species of birds, 2 species of fish, and 428 species of mammals, 36 species of reptiles, 427 species of amphibians and 2.5 million species of insects. In addition to their impeccable beauty, many endangered species live in the Amazon rainforest. The Amazon forest is home to leopards, electric eels, carnivorous cats, venomous duckflies and numerous venomous species of snakes. The river that flows through the Amazon rainforest is known as the Amazon River.
The river originates from the summit of Nevadu Mismi in the Andes Mountains of Peru. It is the second longest river in the world. This river holds more water than any other river in the world. About a thousand tributaries join to form the Amazon River. All these tributaries are the lifeblood of the Amazon rainforest. Of the few major rivers, 17 are more than 1,000 miles long. The Amazon River, which flows through the forest, is very important behind the expansion of this forest. These tributaries are described as effective ways to travel through the vast jungle. The Amazon River has traveled 3,000 miles across five countries in South America and flowed into the Atlantic Ocean.
This river drains about a 20 percent of the world's water into the sea. Where the Amazon River joins the ocean, 4.2 million cubic feet of water falls into the ocean every second. During the monsoon season, the amount of water goes up to 70 lakh feet. The Amazon Basin is the world's largest drainage basin covering an area of about 70 million square kilometers. Of these, only the basin in Brazil is larger than any other basin.
Several circular designs can be seen on the chest of the Brazilian Amazon. The designs are still shrouded in mystery. Soilists are working to find the answer to this riddle. It is thought that the designed parts were used as tombs or burials.
Traditionally, the ancient Amazons were the masters of this design. However, no device that could be used to create this design could be found out by research. Evidence suggests that these installations were stamped from twelve hundred to fifteen hundred years ago. Another hot topic in the Amazon is the one that flows through it.
The river is literally very hot. The maximum water temperature of this river can be up to 93 degrees Celsius. Scientists have not yet been able to find the real cause of the river's heat. The locals think it is a special natural force. As a result, they never swim in it. Among the many species of plants in the Amazon, there is a type of water lily called Victoria Amazonia.
It is named after Queen Victoria of England. Lotus leaves can grow up to 3 meters in size. The Amazon tree provides about 20 percent of the world's oxygen as well as received a large amount of carbon dioxide. For this reason, the Amazon is considered the lungs of the world.
But sadly, deforestation is going on in Amazon as well as all over the world. Deforestation is due to make settlement by cutting down trees. Prior to 1960, entry into the Amazon was banned. At that time only ancient methods were used to cultivate the land in the Amazon. The lands of the Amazon remain fertile for a short time in a year.
That is why farmers are always looking for new land to clear the forest. Construction of the Trans Amazonia Highway began in 1970. Fortunately, the work was stopped as a threat to Amazon.
Even then, by 1990, 4 lakh square kilometers of the Amazon's forest had been destroyed. The amount of deforestation in the Amazon in 2000 was 5 lakh 87 thousand square kilometers. Due to unplanned deforestation, environmentalists predict that the Amazon could disappear in the next 50 years. The rapid deforestation of the Amazon is having a global warming and adverse effect.
The human race's relationship with the Amazon forest is quite old. Most of the people living in the Amazon settled in the riverside areas. They chose accommodation based on transportation, fishing and land fertility.
In the past, the people who lived in the Amazon rainforest were divided into different societies based on conventional beliefs and performance. Even today, 20 million indigenous people of different races live in the Amazon rainforest. The arrival of Europeans in the Amazon in the sixteenth century reduced the number of Amazonians.
Studies show that 11.8 percent of the Amazon's population is using it, but their habitat was not causing much damage to biodiversity. But since the arrival of the Europeans in the Amazon, the biodiversity of the forest has been on the rise.
Currently, the Amazon forest is home to 400 to 500 Amerindian. It is thought that at least 50 of these indigenous ethnic groups have no resemblance to any other civil society in the world.
In Africa also have some indigenous peoples in the jungles who do not want to have any contact with the whole world like these people in the Amazon rainforest.

Farakka is a name of Curse for India & Bangladesh nowadays
Farakka is a name of Curse for India & Bangladesh nowadays
Farakka is located on the river Ganges in the Murshidabad district of West Bengal, India, 16 km from the Chapai Nawabganj border in Bangladesh. In 1971, construction work on the river Ganges began and construction was completed in December 1984. The length of the dam is 2.24 km. It is not just a dam, this infrastructure is also used as a road and rail link. The dam has a total of 109 gates. Water is supplied from this dam to the Farakka thermal power plant. The Farakka Dam was built in the 1950s near the port of Calcutta to clear the silt of the Hooghly River. The Hindustan Construction Company built the dam at a cost of about 1 billion rupees with the help of the then Soviet Union.
After the independence of Bangladesh in 1971, talks started with India on the distribution of water in the Ganges. On 16 May 1974, Sheikh Mujib, the then Prime Minister of Bangladesh, and Indira Gandhi, the then Prime Minister of India, discussed the distribution of water at Farakka Point. The conference decided that India would not blacken the Farakka Dam before the two countries reached an agreement. Although the Bangladesh government in 1975 for only 10 days to test a part of the dam allows India to remove 310 to 450 cusecs of water from the Ganges. But until the dry season of 1976, India carried 1130 cusecs of water from the Ganges to the Bhagirathi River in West Bengal. This kind of injustice done by India to Bangladesh was discussed in the UN General Assembly but India did not pay much attention to it. Despite short-term water sharing agreements in 1978, 1982, 1985 and 1992, India never acted on its word.
India is not abiding by the 30-year water-sharing agreement reached with India in 1996, despite the fact that it is clear. After every agreement, India has been unfairly violating the terms of the agreement. Cubic foot per second is the unit of water measurement for a river or a flowing body of water. Which is called CUSEC for short. According to the Indo-Bangladesh agreement, if the river has 70,000 cusecs of water, both countries will get 35,000 cusecs. And if there is 75,000 cusecs water, India will get 40,000 and Bangladesh will get the rest. India's will is to remove and shut off water from the dam in an uncontrolled manner. As a result, Bangladesh was hit by severe drought in the dry season and cover floods in the monsoon season.
As a result of this arbitrariness centered on the Farakka Dam, not only Bangladesh but India itself is being severely damaged. Even before the construction of the Farakka Dam, the river experts of the two countries opposed it, saying that the dam was built in the course of a huge river like the Ganges or the Padma the natural balance of both upstream and downstream areas will be severely damaged. Thereafter, the Government of India began construction of the Ganges Dam and the digging of feed canals to supply water to the Hooghly and Bagirathi rivers. The length of the feed canal from this dam to Bhagirathi and Hooghly rivers is about 40 km. This reckless project has caused severe environmental catastrophe in the states of Bangladesh, West Bengal and Bihar in India. Under the influence of Farakka, part of the Padma including Bengal has turned into a piece of desert.
As a result of the dam, the Padma has lost its navigability, 2500 km of river paths and 49 tributaries have completely disappeared. The Ganges Basin has undergone tremendous changes in the last four decades since the Farakka Barrage came into operation. The picture of environmental catastrophe is clear today in Bihar and Uttar Pradesh upstream of the Ganges and in the lower reaches of the Sundarbans. Large amounts of silt accumulate upstream of the Ganges and floods occur every year in Uttar Pradesh region including Bihar of India. On the other hand due to the retention of water in the summer season, the normal speed of the river is lost and the downstream Bangladesh is suffering. As a result of the Farakka Dam, millions of people in Bihar are threatened every year. The amount of silt carried by the Ganges towards Bangladesh has come down from 2 billion tons to 1 billion tons. As a result, the formation process of the coastal area at the mouth of the Meghna estuary is being disrupted. If this trend continues, the process of land formation and land acquisition in the coastal areas of Bangladesh will be in jeopardy. Due to this dam, the once defunct Padma is now in a dead state. The green Bengal of this region may soon turn into a desert.
Due to the removal of water from the Ganges during the dry season, there are huge losses in agriculture, fisheries, forestry, industry, shipping, etc. in Bangladesh. In financial terms, Bangladesh loses about 3 billion every year. As the water flow of the Padma is severely reduced in the northern basin of Bangladesh groundwater level in Rajshahi, Chapainawabganj area has dropped by 15 feet instead of 8 to 10 feet. The monsoon rains are not able to meet the water shortage in the region. The process of desertification is caused by the presence of water. Due to lack of water in the dry season, soil moisture has decreased by 35 percent. Lack of humidity increased the day's high and low temperatures. The Gorai river in Bangladesh is completely extinct in this desertification process. Due to the decrease in the flow, the navigability of the river has decreased and as a result large scale floods have to be expected in Bangladesh. In addition, the declining supply of fresh water has a devastating effect on agriculture.
As a result of the drought, the salinity of the soil in Khulna region has increased. Loss of fisheries due to loss of soil moisture, increase in salinity and unavailability of fresh water. Due to uncontrolled flow of water in the Ganges, about two hundred species of fish and 18 species of shrimp are under threat in this area. As a result of declining fish supply, thousands of fishermen have become unemployed.
During the dry season, more than 320 km of waterways in Bangladesh become impassable. Recently, public opinion against India and Farakka is getting stronger because Farakka is now more of a disadvantage than an advantage in Bangladesh. The dam that was built to sustain the Calcutta port, could not be saved 43 years after its construction.
Even the amount of dredging required to keep the port of Calcutta would not have required so much dredging even before the Farakka Dam was commissioned. Before the construction of the dam, the local tribals were told that if the dam was built, there would be no more floods. But the floods have been worse than in the past just because of the dam. Bihar Chief Minister Nitesh Kumar has proposed to break the barrage to stop the year-round floods. But experts and development workers say it is possible to remove the gates of the dam without breaking it and keeping the road and rail communication system intact. In Europe and America, there are many examples of this type of dam being removed if the loss is greater than the profit. Therefore, the immediate removal of this Farakka Dam as a curse for both Bangladesh and India will be beneficial for all.
