The high mortality rate among street children in Brazil is due to a number of factors, including poverty, lack of access to education and healthcare, and social discrimination. Street children are often forced to live in dangerous and unsanitary conditions, and they are often victims of violence and abuse. They are also more likely to suffer from malnutrition and disease than other children.
The Brazilian government has taken some steps to address the issue of street children, but more needs to be done. The government needs to invest more in education and healthcare for street children, and it needs to provide them with safe and affordable housing. The government also needs to work to reduce social discrimination against street children.
