Amazing Underwater World: How miserable is the story of fish extinction in Lake Geneva?
Lake Geneva, a deep lake located on the north side of the Alps, is jointly owned by Switzerland and France, and is one of the largest lakes in Western Europe.However, over time, the underwater world of this beautiful lake has undergone tragic changes.Faced with the impact of environmental changes and human activities, the fish ecology of Lake Geneva has suffered a severe blow, casting a shadow on the originally vibrant underwater world.
Environmental changes in Lake Geneva
The properties of Lake Geneva are affected by the formation process of the lake, including factors such as sedimentation, tectonic folds and glacier erosion.Since ancient times, the waters here have bred a rich biological ecology, especially the native white fish (Coregonus fera), a species that has never been discovered in the lake since 1920.
"In the 1980s, the intense environmental pollution faced by lakes almost extinct almost all fish, with underwater visibility even close to zero."
As the urbanization process accelerates, worrying pollution and ecological changes are coming one after another.The once lush ecological environment has been hit hard by insufficient industrial emissions and sewage treatment.During this period, even the basic water quality standards were unable to meet, which made people wonder whether our natural environment can really bear these man-made burdens?
Extinction and Recovery of Fish Ecology
Lake Geneva was once home to many kinds of fish. However, with the development of the industry, the pollution of lake water has gradually threatened the fish ecology.Since the 1960s, the number of fish in lake waters has begun to drop sharply, and even species have become extinct.The only remaining white fish (Coregonus palaea) is not a native species of lakes, and this situation just symbolizes the collapse of the ecosystem.
Hope for environmental protection actions
However, with the increase in environmental awareness, the water quality of Lake Geneva has been significantly improved.Over the past few decades, Swiss and France's environmental measures have gradually taken root and sprouted in the areas around the lake, and the pollution levels have decreased, and this place is once again considered a safe swimming place.
"Today, the recovery of Lake Geneva has become a successful ecological restoration case, giving people hope to improve the environment."
However, are these efforts enough to revive extinct species?Reconstruction and regeneration of fish require not only clean waters, but also the integrity and balance of the ecosystem.In the next generation of conservation programs, reintroduction and breeding programs for specific fish are under investigation.
Call for measures and future prospects
Environmental protection actions continue, and all walks of life are full of confidence in the protection and ecological restoration of Lake Geneva.Scientists work with the government to strengthen monitoring of lakes and carry out continuous testing of water quality to ensure that the ecosystems in the lakes are healthier.
However, the power of scientists alone is not enough, and everyone can contribute to the protection of the lake.Reducing plastic use, supporting cleanup activities and advocating environmental education are actions that every citizen can actively participate in.
Conclusion
The story of Lake Geneva is a story about extinction and recovery that makes us wonder: Can we work together to protect our underwater world from threats in the face of increasingly deteriorating environmental problems?
