In the mid-19th century, a European explorer came to the Mexican jungle and saw this plant called "Myconia" for the first time. It belongs to the family Melastomataceae, usually more than ten meters tall, has no flowers, but has wide and thick leaves - the sunny side is green, while the shady side is bright purple-red, very special and beautiful. The explorers were attracted by "Mykonia", picked its leaves and fruits, and brought "Mykonia" and other collected rare and exotic animals back to the European continent.

In 1961, a European gave a package of Myconia seeds as a gift to a botanical garden in Hawaii. "Mykonia" has very strong growth and reproduction speed. It wasn't long before "Mykonia" was sold to nurseries and became a very popular ornamental plant on Hawaii Island.

But no one discovered at the time that "Myconia" was a very destructive plant, and its arrival would bring great changes to this land.

Experts point out that although the growth of plants seems peaceful and uncontested, in fact, the world of plants is just like the animal kingdom, full of struggles between the weak and the strong. Plants with strong survivability tend to rob and destroy the survival resources of other plants.

Myconia is one of them. Another alien creature, the dark green eagle-eyed bird from Japan, has unintentionally become the "accomplice" of Maconia. The green-eyed bird is very fond of eating the fruits of Myconia, although the fruits of this plant are very small, with hundreds of seeds in each fruit. After eating the fruits, the dark green eagle-eyes become volunteer sowers. They fly freely in the forest and spread undigested seeds in all directions.

Since there are no natural enemies in "Myconia" in Hawaii, there are temperatures suitable for its growth, fertile soil, sufficient sunlight and water, so each plant can fully stretch around and absorb the nutrients at will. Water and nutrients occupy space. In just over 40 years, the area of ??"Mykonia" on Hawaii's big island has reached 10,000 acres, or about 4,000 hectares. The tall and straight "Myconia" plant is like a big green umbrella. Under its shadow, the relatively short native plants in Hawaii gradually wither and grow because they do not receive sufficient sunlight, water and nutrients. die. It turns out that the local area relied on these native plants to conserve the precious fresh water on Hawaii Island and support a variety of animals that feed on them. What's even more frightening is that the decline in the survival of dwarf plants has also led to the increasingly loose soil of the forest, exposing it to hidden dangers such as mudslides at any time. Faced with the tenacious vitality and irresistible destructive power of Mykonia, biologists likened it to a "green cancer."
