How does sea-level rise threaten the Coastal Louisiana environment?

Sea-level rise poses a significant threat to the Coastal Louisiana environment primarily by leading to increased flooding and saltwater intrusion. As sea levels rise, low-lying coastal areas become more susceptible to flooding during storms and high tides. This exacerbates existing flooding issues, affecting communities, infrastructure, and natural habitats.

Additionally, rising seas can cause saltwater to intrude into freshwater systems, which can disrupt the delicate balance of ecosystems and affect freshwater resources. This intrusion can harm native plant and animal species that are not adapted to higher salinity levels, leading to changes in biodiversity and the overall health of coastal ecosystems. Thus, the consequences of rising sea levels are substantial, making it a critical concern for the sustainability of Coastal Louisiana's environment.
