Amazon Rainforest

Spreading over the soil of Brazil, Venezuela, Peru, Colombia, Ecuador, Bolivia, Guyana, and Suriname, it is the world’s largest tropical rainforest, protecting an area of ​​5,500,000 km² (2,123,562 sq miles) and home to many species of wildlife. I’m here. they are not up to date. In 2009, it was named one of the New Seven Wonders of Nature. Not only as a pristine rainforest, but also because of the diversity of flora and fauna, plus the climate and its vastness, it looks very important among the most beautiful places to be discovered. on earth. Remember, this is a living laboratory, a rich reservoir of carbon, a reservoir of oxygen, and protecting it is our top priority.

The name Amazon is believed to come from a war fought by Francisco de Orellana against the Tapyas and other tribes of South America. As per tribal custom, the women of the tribe fought alongside the men. Orellana derived the name Amazonas from the ancient Amazons of Asia and Africa described by Herodotus and Diodorus in Greek legend.

The rainforest must have formed in the Eocene. It must have formed after a global drop in tropical temperatures, when the Atlantic Ocean expanded sufficiently to provide a warm and moist climate for the Amazon Basin. It must have existed in the absence of a type biome. As the climate dries, savannah spreads widely.

The extinction of dinosaurs and the humid climate may have spread tropical rainforests across the continent. From 65-34 Mya, the rainforest stretched south to 45°. Climate change over the past 34 million years has allowed savanna regions to expand into the tropics. For example, during the Oligocene, rainforests spanned relatively small areas, mostly located above 15 degrees north latitude. It expanded again in the mid-Miocene and retreated almost inland during the Last Glacial Maximum. Did.

During the mid-Eocene, the Amazon basin is thought to have been divided along the middle of the continent by the Purus Arch. The waters on the east side flowed toward the Atlantic Ocean, and those on the west side flowed across the Amazonas Basin toward the Pacific Ocean. However, as the Andes rose, a large basin was created surrounding the lake. It is now known as the Solimões Basin. Over the past 5 to 10 million years, this accumulated water broke through the Purus Arch and joined an easterly flow into the Atlantic Ocean.

There is evidence that during the last 21,000 years, the last glacial maximum (LGM) and subsequent deglaciation caused major changes in the vegetation of the Amazon rainforest. Analyzes of sediments from paleolakes and Amazonian fans in the Amazon Basin indicate that basin rainfall during the LGM was lower than it is today, and this is almost certainly associated with a decrease in moist tropical vegetation in the basin. was doing. However, there are questions about how far-reaching this cut was. Some scientists argue that rainforests have been reduced to small, isolated refuges separated by open forests and grasslands, while others believe that rainforests remained mostly intact, but today They argue that it does not extend as far north, south, and east as is seen. Practical limitations of working in the rainforest mean that data sampling is biased from the center of the Amazon Basin, and both explanations are possible. This proved difficult to resolve as it is well supported by the available data.

Based on archaeological evidence from excavations at Caberna da Pedra Pintada, humans first settled the Amazon region at least 11,200 years ago. Subsequent developments formed late prehistoric settlements around the forest by 1250 AD, causing changes in forest cover. Biologists consider a population density of 0.2 people per square kilometer (0.52 per square mile) to be the maximum a rainforest can sustain through hunting. Agriculture is therefore necessary to accommodate a larger population.

Between 5 and 7 million people lived in the Amazon region, divided between dense coastal settlements like Marajó and inland dwellers. For a long time, these inland dwellers were believed to be sparsely populated hunter-gatherer tribes. Archaeologist Betty J. Meggers was a prominent proponent of this idea, as she explains in her book Amazonia: Man and Culture in a Counterfeit Paradise. However, recent archaeological finds suggest that the area was actually densely populated.

One of the main pieces of evidence is the presence of fertile terra preta (black soil) distributed over large areas of the Amazon forest. It is now widely accepted that these soils are products of indigenous soil management. The development of this soil has made agriculture and forestation possible in a previously hostile environment. This means that much of the Amazon rainforest is likely the result of centuries of human management rather than spontaneous generation as previously thought. In the Xinguanos area, in 2003 Michael Heckenberger and colleagues at the University of Florida discovered the remains of several of these large settlements in the middle of the Amazon forest. Among them were evidence of roads, bridges and large squares.

As you know, the Amazon forest is amazingly rich in flora and fauna. Discussing its wildlife, you can find many native species and native frogs. For example, giant he reef his frogs, birds such as the scarlet macaw, and 2.5 million insect species. It is home to 40,000 plant species, 3000 fish, 1,294 birds, 427 mammals, 428 amphibians and 378 reptiles. Scientists have listed 96,660 to 128,843 species of invertebrates in Brazil alone.

One square kilometer (247 acres) of the Amazon rainforest contains about 90,790 tons of living vegetation. The average plant biomass is estimated at 356 ± 47 tonnes ha−1. To date, an estimated 438,000 species of plants of economic and social interest have been registered in the region, with many more undiscovered or uncataloged. The green leaf area of ​​rainforest plants and trees varies by about 25% as a result of seasonal changes. The leaves develop during the dry season when the sun is at its maximum and fall off during the cloudy rainy season. These changes provide a carbon balance between photosynthesis and respiration. Some of the largest predatory creatures are black caiman, jaguar, cougar and anaconda. In rivers, electric eels can stun or kill with electric shocks, while piranhas have been known to bite and injure humans. Various species of poison dart frogs secrete lipophilic alkaloid toxins through their flesh. There are also numerous parasites and disease vectors. Vampire bats live in rainforests and can spread the rabies virus. Malaria, yellow fever and dengue fever can also be transmitted in the Amazon region.

Farmers near the Amazon forest manipulated forest areas to grow their crops. Because the nutrient content of forest soils is surprisingly low (this is because the Amazon forest is a very active ecosystem and its total primary productivity is high), farmers use the area’s forests for cultivation. continue to harvest. Between 1991 and 2000, the total area of ​​forest lost in the Amazon increased from 415,000 to 587,000 sq km (160,000 to 227,000 sq mi), with most of the forest lost becoming cattle pasture. 70% of the Amazon’s former forest land and 91% of land cleared since 1970 are used for livestock pasture. In addition, Brazil is now the world’s second largest soybean producer after the United States. The soybean farmer’s needs have been used to validate many of the controversial transportation projects currently being developed in the Amazon, the first of his two highways to clear the rainforest. It was successful and led to increased settlement and deforestation. Average annual deforestation rate from 2000 to 2005 (22,392 km2 [8,646 sq mi] year) increased by 18% over the last five years (19,018 km2). [7,343 sq mi] per year). The Brazilian Amazon has seen a significant reduction in deforestation since 2004.

As a result of deforestation, environmentalists fear a loss of biodiversity and a release of carbon that could ultimately contribute to global warming. It accounts for about 10% of the primary productivity and 10% of the carbon stock in the ecosystem with a carbon mass of 1.1 × 1011 tons. The Amazon forest is estimated to have accumulated 0.62 ± 0.37 tons of carbon per hectare per year between 1975 and 1996. Some fear that greenhouse gas emissions will make forests unsustainable and completely disappear by 2100 at this rate.

Between 2002 and 2006, protected land in the Amazon rainforest almost tripled, and deforestation rates fell by 60%. About 1,000,000 square kilometers (250,000,000 acres) are under some protection, bringing the current total area to 1,730,000 square kilometers (430 million acres).

The basin is drained by the Amazon, the world’s largest river by runoff and the second longest river in the world after the Nile. The river is made up of more than 1,100 tributaries, 17 of which extend over 1,000 miles, two of which (Negro and Madeira) hold more water than the Congo (formerly Zaire). River systems are the lifeblood of forests, and their history plays an important role in the development of tropical rainforests. It straddles the borders of eight countries and one overseas territory and is the world’s largest river basin and the source of one-fifth of all free-flowing freshwater on Earth. Its rainforests are the largest and richest on the planet, and are home to an astounding one-tenth of the known species on the planet.

More than 350 indigenous peoples and ethnic groups have lived in the Amazon for thousands of years, using nature for agriculture, clothing and traditional medicine. Today, the region is home to more than 30 million people. Most live in metropolitan centers, but all continue to depend on the Amazon’s ecosystem services for food, shelter and livelihoods. For indigenous peoples, the Amazon rainforest is important because it is their home and their culture is closely associated with forests, rivers and animals. Destroying the forest means destroying all the remaining indigenous peoples. Some Amazonian tribes have not yet come into contact with outside cultures. Can the Indigenous way of life be destroyed? People have lived happily for thousands of years. Humanity will lose language, art, stories, and knowledge.

Deforestation has created many hazards that affect not only forests, but all corners of the globe. We think of Mother Earth as one whole unit that is constantly working and building and all species have ecological niches in their ecosystems. As the world’s largest rainforest, a major catchment area, and a water recycler that absorbs part of it, Amazon is our responsibility. By protecting, maintaining and using it sustainably, all life on Earth, including humans, thrives. Its uniqueness that amazes the whole world would otherwise be lost forever. Scientists and botanists and experts of all types will discover something new every day when they enter this wonderful green cover and imagine that most of the pills and medicines we use are from Amazon. Try it. It’s a stockpile of herbs, a true gift from God. Visit it, admire its beauty, and join hands to raise awareness to save it for the future world.
