 The Amazon Basin is located in brazil. For centuries, this has protected the area, people, and the animals residing in it. Forest recession has occurred in the past 30 years due to increased industry and population growth through road projects, settlement initiatives, and industrial development. 
The Amazon Basin includes a diversity of traditional inhabitants as well as biodiversity in both flora and fauna. These peoples have lived in the rain forest for thousands of years, and their lifestyles and cultures are well-adapted to this environment. Contrary to popular belief, their subsistence living methods do not significantly harm the environment. In the past few decades, the real threat to the Amazon Basin has been deforestation, poaching, and cattle ranching by transnational corporations.
 
Oil and gas development often also takes a heavy toll on the environment and local people; especially in rainforest areas where it can cause displacement of local people, air and water pollution, and construction of roads that open previously inaccessible areas to deforestation. 
That said, even a new NASA study shows that over the last 20 years, the atmosphere above the Amazon Basin has been drying out, increasing the demand for water and leaving ecosystems vulnerable to fires and drought. It also shows that this increase in dryness is primarily the result of human activities. 
Summary: all impacts caused by human development in the Amazon Basin is causing the atmosphere to go bad, the crops and indigenous plants to die at alarming rates, the water to be polluted, and the animals and humans who are indigenous of the area suffer the consequences. 
  
 
        
             
        
        
        
The correct answer is - They formed long ago, and erosion has beveled them to their present elevation.
The Appalachian Mountain Range is one of the oldest mountain ranges on the planet. They have formed in the Ordovician Period, around 480 million years ago. When they formed and were at their peak, the Appalachians were much larger and higher than what they are in the present. The reason for their decline in size is attributed to the erosion. The erosion is a process that removes the material from its original position. This process has been influencing, at different rates, the Appalachians for almost half a billion years. Even though the erosion is not a process that acts very quickly, when put the time that it influenced these mountains we will see that it managed to lower them significantly. That process continues in the present, and in the manner in which the continents are moving, there shouldn't be any force that will help lift up the Appalachians again, but instead they will continue to shrink until they are flattened in the distant future.
