Question

why has mining not developed in the western part of Brazil

Answer 1

Mining could be a profitable economic activity in Western Brazil.

However this is not the case because of the following reasons :

1.) Mining activities pollute the surrounding rivers which affect the native community living around.

2.) Since sometimes the miners are people from other countries, the native communities complain of their cultures being eroded.

3.) Mining also leave the land ugly.

4.) Some of these minerals are found in rainforest and for mining to take place the forests need to be destroyed.

5.) Some minerals such as mercury are harmful to both human beings and animals.

For these reasons mining is not well developed in western Brazil since it has many adverse effects.
