I'm not 100% sure, but I believe it is because the Amazon River flows through Brazil. This is a great opportunity and source of hydroelectric power that can be taken advantage of instead of wasting money on fossil fuels or other power sources.
Jomo Kenyatta helped gain independence for Ghana i hope that helps.
As an ecologist I would bring to the table:
- Air pollution, sound pollution, water pollution, soil pollution.
- Destroying of the ecosystem
- Climate effects
- The process of recuperation of that land, that will take decades, lot of effort by the authorities, ecology organizations and locals, and will cost enormous amount of money.
- Health problems with the population in near proximity.
