"Wolf and Deer" mainly tells the story that 100 years ago, mutton skewers were full of vitality and deer were frolicking in the forest. But behind the deer, there are often wolves ready to kill them. The residents hated wolves. They formed a hunting party and killed more than 6,000 deer. However, because there are too many deer, they eat all the edible plants in the forest, and because there are no natural enemies, infectious diseases are prevalent there. 1942, there were only 8000 sick deer.

After reading this article, I understand that ecological balance is very important. There is an old saying that there can be neither too much nor too little in the biosphere. This old saying is that extremes meet. As the highest-ranking creature in the biosphere, we humans should naturally protect nature. Biosphere is composed of food chain, which can be divided into four types: predatory food chain, prey food chain, parasitic food chain and saprophytic food chain. The food chain, also known as the "nutrition chain", refers to the chain relationship of various organisms in an ecosystem linked by food, which is equivalent to the saying that big fish eat small fish and small fish eat shrimp.

Too much or too little biology will not only lead to ecological crisis, but also the ruthless revenge of nature behind the improvement of human life quality. Through these things, people gradually realize that human beings are not the masters of the earth, and wild animals, like people, are a link in the biological chain and have the right to survive. Abuse of wild animals means indifference to life. Protecting wild animals shows that human beings care about their own survival and development in a deeper sense.

Let's protect and love nature!
