They are the base of the food chain. Almost all animals get their food from plants directly or indirectly. For example, cows eat grass, and people eat cows. So without plants, many animals would not survive. Plants also help keep the environment healthy. They take in carbon dioxide, which is a harmful gas, and release oxygen. This helps to keep the air clean. Trees can also stop soil erosion (水土流失). Their roots hold the soil together, so when it rains, the soil doesn't wash away easily. Some plants have special abilities. For example, the cactus (仙人掌) can live in deserts where there is very little water. It stores water in its thick stem (茎) to use when there is no rain. Another special plant is the Venus flytrap (捕蝇草). It can catch and eat insects because it grows in soil that doesn't have enough nutrients. There are more than 300,000 kinds of plants in the world. They come in different shapes, sizes and colors. Some are very small, like moss (苔藓), and some are very tall, like the giant sequoia (巨杉) tree, which can grow to over 100 meters high. We should protect plants because they are essential for our survival. We can do small things like not picking flowers, planting trees and reducing pollution. ( ) 1.
