The destruction of foreign animals

In the face of red-ear tortoises in Vietnam, there have been many environmental disasters caused by foreign animals in the world. In some places, officials have to hang millions of dollars to find ways to eliminate strange creatures.

Sugar cane

In 1935, sugar cane toad was imported from Hawaii to Australia to destroy sugar beetle beetles. However, they quickly became pests and became the terror of Australia.

Appropriate habitat has made sugar cane toads grow at a dizzying speed. According to estimates by florists, the animal reached 200 million in 2007 and occupied 75% of Australian territory in 2008.

Sugarcane toads can destroy the ecosystem where they live very high. An adult cane toad is very large (more than 20 cm long, weighs nearly 1 kg). Sugar cane is very voracious. They eat all kinds of creatures it finds. In addition, sugarcane toads also compete for food, breeding places with native amphibians, causing serious ecological imbalance.

State governments in Australia devastated by sugar cane toads have declared war on this animal. In particular, Queensland governor Peter Beattie announced that he would award a million-dollar prize to a scientist who finds poison to destroy or inhibit the growth of sugarcane toad.
