1. Water hyacinth’s self-narrative composition Hello everyone, my name is water hyacinth. I am an aquatic ornamental plant, also known as water hyacinth.

My hometown is in South America, and I have traveled to more than fifty countries.

I was wearing a green dress and floating freely on the water.

It blooms in summer, and the flowers are blue-purple, so beautiful.

Not only am I good-looking, but I am also useful.

I am a very good, delicious and natural feed.

I can help humans purify sewage, decompose toxic substances, and protect human health.

But having said that, I also have troubles.

Because I over-propagated, producing thousands of my brethren in two weeks, I clogged the river and caused the death of other aquatic plants.

Therefore, it has recently been called a "poisonous weed" that harms the environment. Hey!

Asians don't understand me. When I was in South America, I had more than 200 natural enemies, so I wouldn't overbreed.

But once I arrived in Asia, I had no natural enemies, so I overproduced.

Why!

I came to Asia, where should I go?

Unexpectedly, time has changed, and abundant domestic garbage and sewage have been discharged into the rivers. The water has become eutrophic, causing water hyacinths to grow wildly and become "green monsters", which is also unexpected.
