The Effects of Erosion and Loss of Marsh Land in the Southern United States

Survey and Purpose Motives Louisiana has about 40% coastal wetlands in 48 states. Louisiana lost 40 square miles of wetland per year (80% of the national annual coastal wetland loss) (lacoast.gov). From a hydrological point of view, wetlands can replace aquifers, maintain excessive floods due to heavy rain, and prevent storm surge. The state benefits from coastal areas of Louisiana. Louisiana is responsible for China's oil and gas production, shipping, fishing, fur harvesting and oyster production, accounting for over 55,000 jobs and proportions.

Petroleum from disasters affected the coastline of the United States from 622 miles around the Gulf of Mexico to the US coastline of 1,300 miles and the erosion of most of the wetland vegetation (plants) caused by oil catalyzed the erosion of the land. The 2012 survey of sand from contaminated beaches and wetlands showed that biodiversity fell sharply since one of the lowest links in the food chain since the spill. The remaining species are considered to be species that promote contamination conditions and consume hydrocarbons. This may have long-term impact on the ecosystem. The first author said, "We will come to this true (poverty) community from this very diverse community, true (fungal species dominate)." The author also expressed concern that trace minerals deposited by metals such as petroleum, mercury and arsenic could harm wild animals and humans.

Because salty wetlands have been discovered all over the world, erosion and disappearance of them are a global problem that will have a global impact. Loss and extinction of habitats of species dependent on salt wetlands for survival and breeding not only causes loss of catastrophic biodiversity but also loss of storm buffer is very dangerous for many countries It can be. More than 35% of the world's mangroves have disappeared, and 50% of the mangroves have disappeared in countries such as Vietnam, India, the Philippines. Many people are in real danger as climate change is getting increasingly intense and bringing powerful storms. Like salty wetlands, mangroves protect human beings and many species, and their losses should be a major concern for everyone.
