The development of the Amazon Basin has caused soil erosion

Soil erosion is defined as the wearing away of topsoil which is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. One of the main reason for soil erosion is deforestation. Amazon being the largest rain forest in the world is in danger due to its development.  More than 20 percent of the Amazon rain forest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year.

there's multiple reasons why the conquistadors were so successful in colonizing central america, and some of them are:

- they were seen as gods;

at the beginning, the spanish settlers were seen by the natives as gods, and this was mainly due to their white skin, and the way they came with their boats.

- possessed superior weaponry;

the spanish had gunpowder and guns, as well as cannons, while the natives did not had any fire weapons.

- made cleaver alliances;

they used the situation of tribes hating each other, so they made alliances with some of them which served them very well.

- brought diseases;

the native people were not immune to certain diseases the europeans brought with them, so they were dying from seeming harmless things for european standards.

a and b because with the other three, they simplify to something else.
