It covers 5,500,000 km2 nelllerena https://padlet.com/nelllerena/460ucvpkqfkg/wish/319939742  
Specialists suggest that in Amazonia there is one tenth of the world species.

Since the Amazonia is a large area and that covers nine countries, having ready list of species is not yet available.
However, here a list of 10 Animal Species Endemic to the Amazon Basin
These animals are only found in the Amazon River or one of its rain forest ecosystems.
  1. Caquetá tití monkey (Western Colombia) (critically endangered)
  2. hoary-throated spinetail bird (Brazil and Guyana) (critically endangered)
  3. pink-throated brilliant hummingbird (Colombia, Ecuador, and Peru) (vulnerable)
  4. fantastic poison frog (Northern Peru) (near-threatened)
  5. Amazon river dolphin (Amazon and Orinoco river basins) (insufficient data to assign a conservation status.)
  6. Amazon bamboo rat (Bolivia, Western Brazil, Colombia, Ecuador, Peru) (least concern)
  7. albina Suriname toad (French Guiana, Guyana, Suriname) (least concern)
  8. southern two-toed sloth (Northern Amazon Basin) (least concern)
  9. black spider monkey (Guyana, Suriname, French Guiana) (vulnerable)
  10. black bearded saki (Northeastern Brazil) (critically endangered).

The five families plants with more endemism are: Orchidaceae, Gesneriaceae, Melastomataceae, Bromeliaceae and Piperaceae. 

Amazonia is not a hot spot of diversity, but there are 713 protected natural areas. For example, The Tambopata National Reserve in Peru has more species of birds (595) than any place of similar size on Earth. Here we see blue-and-yellow macaws, scarlet macaws, mealy amazons, and chestnut-fronted macaws.

The same may be said for the South Pacific hake (Merluccius spp.), a demersal species. Freshwater species also show signs of overexploitation. In Loreto, the average size of freshwater catch has decreased, while the proportion of individuals below reproductive size per catch has increased (IIAP, 2009). overexploitation of other kinds of natural resources(e.g. medicinal plants) is also highly probable. 
Overharvesting is also having a negative effect on Peru’s timber resources, pushing CITES-listed species towards local extinction. About 80 percentof all the commercial timber harvested, sold, and exported from Peru is illegal

Both are part of the Amazonia, and both megadiverse countries.
Peru is almost same size than Colombia, however Peru has 75 natural protected areas, which represents 15.21% of the country surface area. 
  1. National parks, 12
  2. National sanctuaries, 9
  3. Historical sanctuaries, 4
  4. National reserves, 15
  5. Wildlife refuges, 3
  6. Landscape reserves,2 
  7. Communal reserves, 8
  8. Protected forests, 6
  9. Hunting enclosed lands 2; and 
  10. Reserved zones, 14. 

Peru with over 1,700 species of birds, has the world's second most diverse avian community, after Colombia. One possible reason, why Colombia has the most diverse avian community is the increase of inventories, since the war ended.

Colombia has unique biomes like Chocó- Darién Moist Forests, Savanas; and Peru has yungas, selva amazonica suroccidental, puna, and Sechura Desert. 
Both: Bosque Andino del Norte, Selva del Napo, Selva del Rio Negro y Yurá, bosque seco ecuatorial, páramo andino, and manglar (sorry for writing this in Spanish)

I have chosen Amazonia as my BioArea, it is the biggest neotropical forest. As the biggests land, many think on the potential economic gain that they will obtain and little on what are we are losing as a entire planet. People is threatening Amazonia with our consuming behaviuor.
 
I feel that when talking about Amazonia away from Southamerica, the government of these countries are only the one to be blame for.
That is exactly where people should look, to ourselves and our consuming behavior.
 
The conversion of Amazonian forest to pasture for cattles is the dominant cause of deforestation. What can we do for preventing that? some think on making the cattle ranching more efficient and manage with better technology. Others, like me, think that educating people and changing our consume habits might be a better solution. I do not believe in the intensification of the beef production will work, without changing the behavior of the consumer. 
 
The use of forest for growing soy, oil palm and corn is also a key pressure. Oil palm production is devastating other tropical forest like Indonesia; Palm oil is not only bad for the climate: As their forest habitat is cleared, endangered species such as the orangutan, Borneo elephant and Sumatran tiger are being pushed closer to extinction. Smallholders and indigenous people who have inhabited and protected the forest for generations are often brutally driven from their land. In Indonesia, more than 700 land conflicts are related to the palm oil industry. Human rights violations are everyday occurrences, even on supposedly “sustainable” and “organic” plantations.
 
Again, if we consumers, say no to those products or consume less of them, the big international companies would no pressure as much. The reason is simple, they provide which people ask for it. There is money involve. If they sell is because there is people that consumes. In this time, me or you personally we do not go and kill the dodo, we send somebody to do it for us, and the worst of this scenario, is that me and you feel clean, we do not feel involved.
 
What can we do? Educated yourself and others and live a simple life. My make up, or a great beef in my plate, is not worthy the destruction of the forests. It is hard, I know, I do not want to stop using that gorgous body cream that makes my skin fresh…
Really I would like to see the scenario in a more positive way, but unfortunately I can not. People living in the cities, are more and more disconnected from nature, how can we protect it if we do not even see it? 
Other treateans are dams and hydropower expansion. The area at risk from deforestation impact occurs between 40 and 100 km from hydroelectric dams. There are 154 constructed dams, and another 277 either under construction or planned in the Amazon biome. Sites selected for dams and reservoirs often overlap with protected areas and indigenous territories. 
 
Any commercial activity creates the construction of roads, giving access to remote areas, bringing people and land speculation inwards. Mechanisms to manage or reduce the impacts of new roads are often absent or poorly implemented. Greatest deforestation rates are in areas with more roads, showing a strong correlation between deforestation and the presence of roads and projections of new roads. Nearly 95 per cent of deforestation in the Brazilian Amazon was found to be within 5.5 km of roads and 1km of navigable rivers.
 
Forest fires due to poorly controlled burning for land clearance and management are a contributing factor to both deforestation and forest degradation. Road development accompanies mines, oil and gas drilling, often deepening deforestation. Mining is significant in places such as Peru, where artisanal and small-scale alluvial gold mining has increased 400 per cent since 1999.Unsustainable legal and illegal timber trade contributes to forest degradation and can be the first stage of forest conversion.

Meanwhile humans are producing high emissions of CO2; Amazonian rainforest takes and uses CO2 to produce oxigen and water,  counterparting in this way the greehouse effect. When deforestation occurs, trees that are layed down releases the captured CO2, and the precipitation patters are altered. In forests that have been cut, logged and fired stores 40% less carbón than undisturbed one. (https://amazonaid.org/the-issues/climate-change/)
 
I have found models about what would happen to Amazonia if we continue deforestating the Amazon. Sooner or later (by 2030 or 2050) the temperatures in the Amazon will increase by 2–3°C. At the same time, a decrease in rainfall during dry months will lead to widespread drying.
 
The optimistic view, by 2050, is not considering the synergy of the land use change of the forest, the effect of deforestation and regional climate change. If those are considered, 55% of Amazonia rainforest would be destroyed or severly damaged earlier than that, possibly in 11 years time, meaning 2030 (Nepstad 2008).

 The projected increases of temperatures and decrease of rainfall during already dry months could result in longer and perhaps more severe droughts, along with substantial changes in seasonality. 
Coupled with land-use changes, we can expect the degradation of freshwater systems, loss of ecologically and agriculturally valuable soils, increased erosion, decreased agricultural yields, increased insect infestation, and spread of infectious diseases.
