Combination Of Rising Sea Levels And Subsiding Land Endanger Louisiana Coast

AVERY ISLAND, LA - AUGUST 21: Algae covers a pond in a wildlife refuge on Avery Island, home of the Tabasco hot sauce factory, on August 21, 2019 in Avery Island, Louisiana. Avery Island, a dome of salt surrounded by marshes near the southern Louisiana coast, is where the iconic Tabasco sauce has been made for the past 150 years. Like much of southern Louisiana, coastal marshland around Avery Island is disappearing at a rapid pace and the island is losing about 30 feet of surrounding protective marshland per year. As land gradually retreats from the area, the island becomes more susceptible to flooding from severe storms.
