It is impossible not to kill animals. The meat we eat is to kill cows, sheep and pigs. Killing these non-endangered animals, rapid reproduction, no harm to the environment. Protecting the biosphere is of great significance. In a word, it is for the survival of mankind. If the biosphere is destroyed, even if human beings are lucky enough to survive without other organisms, they will not only lose their food sources immediately, but also die slowly because of the disruption of biological balance and the loss of biodiversity, resulting in a series of chain reactions such as air pollution and water pollution. Humans are not creatures that dominate the earth, nor can they dominate other creatures, because we depend on them for survival. Humans depend on other creatures for survival, and other animals depend on the environment for survival. In the final analysis, human beings wantonly destroy their living environment, but inevitably, the environment will also be destroyed by natural factors such as volcanic eruptions. Therefore, what we can do is not only to protect the most endangered animals-the most important thing is to control the unspoiled environment, repair the damaged environment and avoid more animal extinction. What we can do is not something shocking, but something convenient around us. Throw less paper towel, pass by the store when you are thirsty, waste an aluminum can or plastic bottle, spit a piece of gum, walk more and drive less. These are all things that we should do easily. Protect the environment, starting from you and me, starting from small things. Nothing is for the generosity of the whole earth. Selfishly speaking, human beings protect the environment for themselves.
