What kind of natural phenomenon is the super-beautiful underwater forest in Wuhan?

Super beautiful underwater forest appears in Wuhan. This natural phenomenon is caused by our own reasons, because there used to be sewage or garbage in the East Lake of Wuhan, but in recent years, due to the improvement of the whole environment, aquatic plants have been planted in the water, making the environmental ecosystem of the whole water body better. In fact, this scene was caused by human intervention. In this case, we can see that the water is clear and fish and others are in the water.

In normal times, most of the rivers we see may be polluted rivers. In recent years, we have dumped garbage or discharged sewage into the river, so the river itself is not clean.

For the sewage discharged from most cities, it may be put into the rivers near us, which is more convenient to deal with. But at that time, I didn't consider the future environmental problems. As time goes by, if we are faced with a series of environmental problems now, we will come up with a series of measures, just like things need to be classified now.

For us ordinary people, environmental protection is also our important responsibility, because each of us has the obligation to protect our environment and our home will become more beautiful. Of course, what we are facing now is the problem of sewage discharge. After the sewage is treated, it can be discharged into the nearest river, but the sewage must be treated well. Facing the beautiful underwater forest in Wuhan, we see such a scene. It is actually a natural phenomenon of human intervention. When the river reaches a certain clarity, we can see aquatic plants and creatures in the water. In fact, this is what we call a natural phenomenon, which is only the result of our own efforts. ?
