The economic boost-over 19,000 jobs will be produced. This will not only have an economic advantage but the population will be much happier and less willing to have to turn to crime to earn money. This benefits Brazil's needs to improve its critical crime rates, with over 1 million homicides a year. This is a highly significant factor as it affects social, economic and environmental issues in Brazil.
$800 million is being put into two conservation parks where animals and plants could possibly even thrive better than they do in the natural rainforest, which is always under threat.
There will be a large social advantage in remote areas of Brazil as job opportunities for the dam rise and more people live in modern villages in secluded areas of Brazil. This paves a way for more necessary development in far-flung parts of Brazil, giving a huge social and economic advantage.
most significant disadvantages
The dam will cost $18 billion to construct overall. This will result in a severe economic blow to Brazil, invalidating any advantages the 19,000 jobs held. Tax will increase to accommodate this hefty cost, and people will be affected, possibly even turning to crime to feed themselves or their family. This is a highly significant factor as it has serious repercussions for the social and economic issues Brazil is trying to overcome with projects like these.
1500 square km of Amazon rainforest, which is already being slowly eradicated globally, will be destroyed for the dam. This has a severe negative impact on not only Brazil's environment, but the entire world's-valuable plants, animals, and trees will be destroyed and the project will only encourage more destruction.
20,000 indigenous people will be displaced, angry with the government for the destruction of their homes. This will cause mass social disruption as they are angered and it violates their human rights. Furthermore, the economy will have to accomodate 20,000 more people who have never lived an urbanized, alien lifestyle. This is highly important as it will create grave difficulties for Brazil in the economic and social sectors which it is trying to drastically improve to achieve its ambitions.
