Answer:
The Amazon rainforest is the largest, most diverse, and beneficial ecosystem in the world. The Amazon rainforest region is a tropical rainforest located in the northern part of the South America continent, it stretches across the countries of Brazil, Bolivia, Ecuador, Peru, Colombia, Venezuela, Suriname, French Guiana and Guiana. Serving as the world’s largest specie rich biome, the rainforest offers the world many different types of benefits. Yet the effects of societies under appreciation for it has took a toll on its natural mission. The following presentation identifies and explains the natural characteristics of the Amazon rainforest. It will also discuss the impact humans currently have on it as well as their future impacts. The presentation will also provide individual strategies that will aid in preserving the Amazon for future generations.
The Amazon rainforest is a tropical forest. The Amazon covers 2.5 million square miles and extends across nine nations; with 60% of the rainforest, the majority of the forest lies in Brazil. The Amazon embodies more than half of the planets remaining rainforest it’s also the worlds biggest and most specie diverse tropical rainforest region. The Amazon provides numerous natural resources to the world. With its ability to supply 20% of the earth’s oxygen through the planets continuously reprocessing carbon dioxide into oxygen, the Amazon was nicknamed the “Lungs of our Planet. The Amazon River which starts in Peru and flows for over 4,000 miles and meets the Atlantic Ocean in Brazil is the Rainforests life supply. The Amazon Rainforest drainage is home to the world’s largest biodiversity. It is estimated that more than half of the world’s animal, plants and insects live in the Amazon. The rainforest bird’s of the Amazon account for more than one third of the world bird species. Additional 70% of anticancer planets are found in the Amazon.

Explanation:
Based on archaeological evidence from an excavation at Caverna da Pedra Pintada, human inhabitants first settled in the Amazon region at least 11,200 years ago. Subsequent development led to late-prehistoric settlements along the periphery of the forest by AD 1250, which induced alterations in the forest cover.

For a long time, it was thought that the Amazon rainforest was only ever sparsely populated, as it was impossible to sustain a large population through agriculture given the poor soil. Archeologist Betty Meggers was a prominent proponent of this idea, as described in her book Amazonia: Man and Culture in a Counterfeit Paradise. She claimed that a population density of 0.2 inhabitants per square kilometre (0.52/sq mi) is the maximum that can be sustained in the rainforest through hunting, with agriculture needed to host a larger population.However, recent anthropological findings have suggested that the region was actually densely populated. Some 5 million people may have lived in the Amazon region in AD 1500, divided between dense coastal settlements, such as that at Marajó, and inland dwellers.By 1900, the population had fallen to 1 million and by the early 1980s it was less than 200,000.
The first European to travel the length of the Amazon River was Francisco de Orellana in 1542. The BBC's Unnatural Histories presents evidence that Orellana, rather than exaggerating his claims as previously thought, was correct in his observations that a complex civilization was flourishing along the Amazon in the 1540s. It is believed that civilization was later devastated by the spread of diseases from Europe, such as smallpox.
Since the 1970s, numerous geoglyphs have been discovered on deforested land dating between AD 1–1250, furthering claims about Pre-Columbian civilizations.Ondemar Dias is accredited with first discovering the geoglyphs in 1977, and Alceu Ranzi is credited with furthering their discovery after flying over Acre.The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.Terra preta is found over large areas in the Amazon forest; and is now widely accepted as a product of indigenous soil management. The development of this fertile soil allowed agriculture and silviculture in the previously hostile environment; meaning that large portions of the Amazon rainforest are probably the result of centuries of human management, rather than naturally occurring as has previously been supposed.In the region of the Xingu tribe, remains of some of these large settlements in the middle of the Amazon forest were found in 2003 by Michael Heckenberger and colleagues of the University of Florida. Among those were evidence of roads, bridges and large plazas.
On 3 September 1989, Varig Flight 254 crashed into the Amazon, killing 13 out of the 54 people on boar On 26 September 2006, Gol Transportes Aéreos Flight 1907, a Boeing 737-800, collided with an Embraer Legacy 600 above the amazon. The Legacy jet landed safely, but flight 1907 lost control, broke up in mid-air, and crashed into the Amazon, killing all 154 people on board.
