AMERICAN BULLFROG AND THE BROWN TREE SNAKES

Context: Two invasive species, the American bullfrog and the brown tree snakes, have cost the sphere an assessment of $16 billion.

Details:

The estimated dip in the world economy is recorded between 1986 and 2020.
The species have caused issues ranging from crop destruction to power cuts, as per a study.
The brown tree snakes have the most significant impact on Pacific islands, and the amphibian breed of the American bullfrog multiplied uncontrollably in Europe.
The brown-and-green frog known as lithobates catesbeianus that can weigh over 2 pounds (0.9 kilos), had the greatest impact in Europe.
The brown tree snake, or boiga irregularis, has multiplied uncontrollably on Pacific islands including Guam and the Marianna Islands, where the species was introduced by U.S. troops in World War II.
The snakes have at times been so abundant that they caused power outages by crawling on electrical equipment.
This signals the need for investment controlling global transport of invasive species to avoid paying for mitigation after the invasions occur.
