Water splashing by the sea is nothing more than one of the best leisure activities in the hot summer, but Haifa, a large city on the Mediterranean coast of Israel, which is famous for water activities, has lost many tourists this summer, which has greatly hit the tourism industry's income, which turned out to be because a large number of jellyfish invaded the coastal sea with climate change, which not only dissuaded tourists, but also highlighted the warning of ecological imbalance.
According to foreign media reports, the huge increase in jellyfish in local waters continues to sting swimmers, resulting in a large loss of tourist crowds, and related industries have lost up to $10 million. Israeli officials said that not only the tourism industry has been hit hard, but also industry and fisheries have not been spared, and the number of jellyfish in the sea has continued to increase in recent years, resulting in the blockage of large fishing nets and the desalination of industrial and industrial pipelines.
Guy Lavian, a marine conservationist at the Israel Natural Parks Authority, said in an interview that as the temperature of the sea rises, they have also observed an increase in jellyfish populations, "which cause considerable damage, and the large number of jellyfish populations that proliferate can be directed to global warming factors."
The increase in water temperature contributes to the rapid reproduction of jellyfish, and the increase in number will also affect the foraging and habitat of the remaining marine organisms, compressing the living space; According to research by the Israeli Society for Ecological and Environmental Sciences, overfishing by humans is also one of the reasons why jellyfish have an advantage in survival.
In addition to rising temperatures and overfishing, Egypt's Suez Canal is also one of the reasons for the proliferation of jellyfish, which is the route of jellyfish along the Red Sea into the Mediterranean Sea. According to ISES, there are now a total of 17 species of jellyfish in the Mediterranean waters, most of which are non-toxic. Agricultural fertilizers that flow into the sea along the waters are also one of the sources of nutrition for jellyfish reproduction, the association said.
