The Guanabara Bay has been the biggest victim of water pollution disasters in Brazil. The worst incident that occurred was in 2000 when 340,000 gallons of water were released into the Bay causing many species of fish to go extinct. The fishing industry that was previously thriving in the area suffered huge blows as 4,000 of 6,000 fishermen had to scavenge for other sources of income, due to lack of adequate catch.
