Natural hazards:
recurring droughts in northeast; floods and occasional frost in

Environment - current issues:
deforestation in Amazon Basin destroys the habitat and endangers a
multitude of plant and animal species indigenous to the area; there
is a lucrative illegal wildlife trade; air and water pollution in
Rio de Janeiro, Sao Paulo, and several other large cities; land
degradation and water pollution caused by improper mining
activities; wetland degradation; severe oil spills

People Brazil
Population:
188,078,227
note: Brazil conducted a census in August 2000, which reported a
population of 169,799,170; that figure was about 3.3% lower than
projections by the US Census Bureau, and is close to the implied
underenumeration of 4.6% for the 1991 census; estimates for this
country explicitly take into account the effects of excess mortality
due to AIDS; this can result in lower life expectancy, higher infant
mortality and death rates, lower population and growth rates, and
changes in the distribution of population by age and sex than would
otherwise be expected (July 2006 est.)
