sapling vertically and gently put it into the pit. I helped the saplings and little east picked up the spade and raised the soil with a shovel and a spade. The tree pit became smaller and smaller, and slowly became a small soil bag. Then we went to pick up a bucket of water, poured it on the root of the tree and said to the little tree, “drink, drink, grow up when you’re full.” The sapling swayed gently with the wind, as if nodding to promise us. Unknowingly, it was the evening, and the colorful glow sprinkled on the earth. The small saplings were like neatly lined up students doing radio gymnastics. We were so tired that we had back pain and panting, but looking at this small sapling and thinking that it would be lush in the near future, the students were very proud. On TV and in books, I often see pictures and records of people cutting down a large number of trees, because they cut down at will, the green of the motherland is decreasing, the land is losing, and large tracts of desert are replaced. But now, with the continuous improvement of people’s living standards, we all know the importance of the environment and begin to plant trees and protect trees. I also wanted to contribute to the protection of the environment, so I decided to plant trees on the small soil slope with my father when the arbor day came on March 12. In the early morning, the sun was shining brightly. We were walking on the road with great interest. When we thought of making a contribution to the greening of the motherland, we were very excited and couldn’t help but speed up the pace. Before we got to the small slope, my father and I saw many people from a distance who didn’t know what to do there. I can’t help wondering: why is the small earth slope so busy today? When I looked closer, I knew that everyone also wanted to contribute to the greening of the motherland. They all came to plant trees! Watching everyone working in full swing, we were unwilling to show weakness. We immediately picked a position, put down the saplings, and couldn’t wait to pick up the shovel to dig a hole. Dad was so strong that he dug a hole at once. As for me, if I didn’t dig a well, I was sweating and tired. But I kept on digging and thought: I must add more green to my motherland. Finally, the pits were dug. My father and I put the saplings in, buried them with soil and watered them, even if we finished the tree species. Looking at the small saplings planted by myself, I think: small saplings, grow up quickly and add a green to the motherland! Look at the people around who have bee “mud monkeys”, who are still busy. I have a feeling: Yes! Who would be unhappy to contribute to the protection of the environment? In the future, I will not only protect the environment and take good care of flowers and trees, but also mobilize everyone to protect the environment, take good care of flowers and trees, and strive to change our home back to the original endless green with everyone! Driven by food demand and supply, the degree of land use has increased sharply. In the 1980s, the grain yield per hectare of agricultural land was 1. 8 tons, now 2. 5 tons. However, this unsustainable land use has caused serious land degradation, which has attracted great attention of the international munity, especially in developing countries and regions with concentrated drylands. Land desertification is related to the survival and development of all mankind. Therefore, people have turned their attention to what we can do. China is one of the countries in the world with a large area and wide distribution of desertification and is most seriously affected by desertification. The total area of desertification land in China has reached 263. 620000 square kilometers, accounting for one third of the land area。 Desertified land 173. 970000
