Comments on Dagang Wetland Park

(⊙o⊙)？ Which school are you in?

There is always a touch that makes us burst into tears, and there is always a force that shakes our hearts. Wetland messengers are doing seemingly simple activities, but they are actually overcoming difficulties that ordinary people are not easy to detect and overcome.

Watching the self-made videos of wetland messengers and tasting their confident faces with smiling faces, I understand that we still have a lot of meaningful things to do. When we see the fruits of labor, we will throw our hardships to the outside world.

I know that a person's strength may be small, but with like-minded friends, he has the courage to accept the biggest challenge. Environmental protection is not a person's business, and protecting wetlands is not just the responsibility of fishermen. We usually value our direct interests, but we don't know that in this society, everything has a predetermined cycle. We wasted a drop of water today, and a slice of fresh water will gradually disappear tomorrow. When wetlands are degraded and fresh water resources disappear, do we know that we are the head of all evils?

What impressed me most about the exhibition of wetland achievements was everyone's enthusiasm for environmental protection. What moved me most was the tired backs of the wetland messengers. The most embarrassing thing for me is that I am still doing some evil deeds that destroy the environment in my life. This achievement exhibition is not to show off or warn, but a spiritual transmission, an ideal in handover and an idea in communication.

Too many words can't fully explain my inner thoughts, but I know I am really moved. I was angry to see the dense bones left by poachers after killing animals. My eyes filled with tears when I saw that the protector risked his life to stop poachers. People have feelings, so I don't understand the selfish and cruel behavior of poachers, perhaps forced by life or driven by interests. Can we think about how much time we have to survive when they disappear, and whether we can survive when the environment is destroyed? No one wants to admit that people are short-sighted. Everyone is imagining how big the world is. Losing a precious animal will not affect the whole, or when killing one animal, maybe another one will be born again. Everyone has this idea, everyone knows the consequences, but we still take it from nature with luck. I believe that we will use a hundred times or even a thousand times to compensate for our mistakes. Therefore, I want to warn you that great events are great because they are made up of countless small things. Protecting the environment, starting from the small things around us, will be greatly improved.

3.2 Wetland Description
