Invasive Species: Snakes and Frogs have done more harm to the world than no other!

American Bullfrog and Brown tree Snake: – Be it a farmer or a person living in the world, there is a lot of trouble with animals and insects. It also takes various measures to avoid them.

Despite this, animals do a lot of harm to humans. Scientists had done a study about the harm caused to humans by animals. Scientists assessing the economic damage caused by invasive insects found that two species are responsible for damage than any other.

According to BBC report, the American bullfrog and brown tree snake have collectively caused $16.3 billion (about Rs. 13 trillion) in global damage since 1986, where these organisms caused damage to the ecological system. At the same time, agricultural crops have been destroyed and electricity supply has also been damaged. The researchers hope their findings will encourage more investment to help prevent invasive species in the future. Writing in scientific reports, the scientists blamed the brown tree snake alone for the total loss of $10.3 billion.

The huge population of these snakes in Guam causes massive power outages, as they slip over electrical wires and cause damage. More than two million of these brown tree-dwelling snakes are found in this small pacific island. It is estimated that there are 20 snakes per acre in the Guam forest.

At the same time, there has been a significant increase in the number of American bullfrogs in Europe. These frogs can grow up to 30 cm (12 inch) in length and weigh up to half a kilo. People troubled by these frogs have been forced to put up expensive frog-proof fencing around the house. According to scientists, the authorities in Germany had to close only 5 ponds to stop these frogs at a cost of 270,000 pounds. It is said that these frogs can eat anything.
