A Research reveals that invasive species that destroy plants and forests, spread diseases and destroy ecosystems are spreading more rapidly around the world. This issue is not yet capable of being overcome by humans.
According to the Intergovernmental Scientific Advisory Committee of the Convention on Biological Diversity PBB (IPBES), this failure has resulted in losses of over US$400 billion (approximately Rp6.3 trillion) per year in damages and lost income.
More than 37,000 recorded alien species have spread far from their native places. Like the water hyacinth clogging Lake Victoria in East Africa, rats and brown snakes destroying bird species in the Pacific, and mosquitoes causing the spread of the Zika virus that causes yellow fever, dengue and other diseases . This number has continued to increase fourfold every decade since 1970.
One report states that economic expansion, population growth and climate change will increase the frequency and extent of biological invasions, as well as the impact of invasive alien species. However, only 17% of countries have laws or regulations to manage this onslaught.
Scientists say that the spread of this species is clear evidence that the rapid expansion of human activity has radically changed natural systems, bringing the earth into a new geological epoch, the Anthropocene.
There are hitchhikers
Hitchhiker or let’s call it a species that hitchhikes and disturbs the natural habitat. The water hyacinth that covers 90% of Lake Victoria once paralyzed transportation routes, smothered aquatic life, blocked water from hydroelectric dams and had become a breeding ground for mosquitoes. Belgian colonial officials in Rwanda initially believed it to be an ornamental garden flower, before eventually spreading to the Kagera River in the 1980s.
A Florida swamp, the Everglades, is full of the spawn of domesticated animals and destructive plants, from five-meter-long Burmese pythons and walking catfish to Old World climbing ferns and Brazilian peppercorns.
In the 19th century, British settlers brought rabbits to New Zealand to hunt and eat. Because they bred like rabbits, officials imported small, ferocious carnivores called civets to reduce their numbers. However, badgers are targeting easier prey, namely dozens of endemic bird species that are rapidly being exterminated, from small kiwis to wrybills.
Elaine Murphy, a scientist at New Zealand’s Department of Conservation, told AFP the story was similar to that in New Zealand and Australia, where worse things involving rabbits have happened. This case study is about how not to control an imported parasite with another imported parasite
Invasive species often arrive accidentally by hitchhiking in the ballast water of cargo ships, in containers in ships’ holds, or in tourists’ suitcases. The existence of habitats that are not native to their natural habitat has meant that the Mediterranean Sea is full of fish and plants that are not native species, such as lionfish and killer algae, which come from the Red Sea via the Red Sea Channel. Suez.
