What are the adverse effects of wetlands on wildlife once they are destroyed?

Migratory birds that depend on wetlands for survival can only migrate, but it takes a long time for animals to adapt to the environment! If they can't find the right food and environment in a place where they can fly, most of them will be wiped out (predators, starvation, intraspecific struggles, etc.)! In addition, the amount of water stored in the land will be greatly reduced, and the aquatic animals in the wetlands will ...... die

It is facing a series of severe challenges such as shrinking area and declining quality.

With the continuous progress of science and technology and the increasing social and economic development, human beings have accelerated the pace of obtaining resources and wealth through the development of wetlands, but in the process of development, little has been done to protect wetlands due to economic interests. Due to the irrational use of land, soil acidification and other forms of pollution have been caused, which has seriously damaged the ecological environment in wetlands and brought heavy disasters to global wetland resources.

For example, in the southern region of the state of Mato Grosso in central Brazil, the Pantanal Marshland, which covers an area of 25 million hectares, contains four ecosystems that are representative of South America: wetlands, savannas, Amazonas and Atlantic forests, with a large number of rivers, lakes and flooded or partially submerged plains.

In addition to the abundant plant resources, the marsh is home to 650 species of birds, 230 species of fish, 95 species of mammals and 167 species of reptiles, and 35 species of amphibians, including rare and endangered animals.

In general, there are three main reasons for the serious damage to wetlands. The first is unreasonable reclamation, including land reclamation by enclosing lakes, reclaiming land from the sea, intercepting water sources, and reclamation of tidal flats; the second is the overexploitation of biological resources, including repeated hunting, fishing, mining, and large-scale peat extraction; Third, pollution is becoming more and more serious, mainly because the severity of water pollution has far exceeded the ability of water purification.

Summary. 1.open (enclose) reclamation and drain natural wetlands, and permanently cut off the water sources of natural wetlands; 2.

Unauthorized landfilling of natural wetlands, unauthorized sand mining, mining, and soil extraction; 3.discharging industrial wastewater, domestic sewage and other wastewater and sewage that pollute wetlands that do not meet the discharge standards of water pollutants, dumping, stacking, discarding, and scattering solid waste; 4.Overgrazing or indiscriminate harvesting of wild plants, overfishing or extinction fishing, excessive fertilization, pesticides, bait and other planting and breeding behaviors that pollute wetlands; 5.

Other behaviors that damage wetlands and their ecological functions.

Yes, over-nourishing plants and animals is an act that destroys wetlands and their ecological functions.

Isn't it. Yes.

Causes of wetland destruction Industrial sewage discharge, chemical contamination will cause the complete disappearance of living things.

Surrounding lakes and creating fields, people indiscriminately fishing and killing birds, and biological invasions.

Hazards: The loss of wetlands is a direct threat to the survival of human beings, and some even predict that our planet is facing another mass extinction in the era of dinosaur extinction. As a member of the biosphere, we have a responsibility to protect our wetlands and our partners.
