Nutria were introduced to the Louisiana ecosystem in the 1930s, when they escaped from fur farms that had imported them from South America. Nutria were released into the wild by at least one Louisiana nutria farmer in 1933 and these releases were followed by E. A. McIlhenny who released his entire stock in 1945 on Avery Island. [ 51 ]
Several examples of invasive species that contribute to the degradation of water quality are listed below. Nutria were introduced to the Southern United States in the 1800s for fur trading. Since their introduction, nutria have reproduced to form large populations, leading to water pollution and erosion.
The story of the nutria is not unique. Many species of birds, mammals, fish, and plants have been introduced into the Louisiana environment in the past two centuries. Exotic species, or species that have been introduced to areas outside their native range, take heavy tolls on the ecosystems they colonize.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...

Invasive species in Florida are introduced organisms that cause damage to the environment, human economy, or human health in Florida. [1] Native plants and animals in Florida are threatened by the spread of invasive species. [2]
Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems. Health problems attributed to air pollution include premature death, cancer, organ failure, infections, behavioral changes, and other diseases.
The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far.
