How did Hurricane Katrina affect the natural environment?

Hurricane Katrina, which struck in August 2005, caused significant damage to the natural environment, particularly in Louisiana and Mississippi. The storm surge led to widespread coastal erosion, destroying wetlands that serve as crucial buffers against storms and habitats for wildlife. Additionally, the flooding resulted in the contamination of water bodies with pollutants, chemicals, and debris, harming aquatic ecosystems. The loss of vegetation and altered landscapes also disrupted local biodiversity and contributed to long-term ecological changes in the region.
