We live on a beautiful and fragile earth, and the earth is like a kind mother, raising us. She selflessly gave everything to human beings, but human beings asked Mother Earth for resources without restraint, which caused her serious injury and great pain. In the past, the river was crystal clear, and you could see small fish swimming around happily. Now the factory regards this river as a good place to discharge sewage in order to improve efficiency. The river was polluted by sewage, and passers-by quickly left. Trees used to be full of branches, birds singing and flowers smelling. Nowadays, people cut down a large number of trees, resulting in a large number of green plants, which not only makes birds lose their homes, but also causes natural disasters such as collapses and floods. Without trees, our earth seems to have lost a pillar; Without green, we humans seem to have lost a natural barrier. Mother Earth is angry. She waved her hand here, and a snowflake turned into ice and snow; She sneezed there, and the rainstorm poured down, and I don't know how many farmland and buildings were flooded; Take another breath, and the glaciers in the South Pole and the North Pole are melted by tears as if they had been baked by fire. There is only one earth in the world. The earth is the home of mankind, with beautiful mountains and rivers, birds and flowers. Improve the environment, protect the home, purify the environment and beautify the home. To protect the environment, we should start from ourselves, bit by bit. Let's take action to protect the earth and repay all the benefits it has given us. As the saying goes: take it in moderation, use it in moderation, and it will always be enough; Take it too much, use it too much, and it is often insufficient. Therefore, we should be grateful, care for the earth and make contributions to environmental protection. If each of us can take action, we can save every drop of water, garbage, saliva and so on in our daily life. Starting from me, starting from you, starting from small things, we will jointly protect our homeland and make our earth bluer, clearer, more beautiful and cleaner!
