People depend on plants. We use plants for food, cloth, shelter (住处), and even the air we breathe (呼吸).
Plants keep our air and water clean. Green plants give us oxygen (氧气). Oxygen is part of the air we breathe.
Plants are also part of the water cycle (水循环). Most of the water that a plant takes in goes back into the air.
Plants give us a lot of the food on the earth. Fruits, vegetables, and grains (谷物) come from plants. Without plants, we would not have bread, rice, carrots, apples, oranges, or bananas! Many people are growing plants to eat in their own gardens at home. Having your own garden helps the earth as well.
When you grow your own fruits and vegetables, you help cut down on pollution because big trucks don’t need to take your food to shops. You also help reduce the amount of rubbish because you don’t need to use bags for packing your food. You can just pick it out of the ground or off a plant and put it into a basket!
Trees are an important plant resource (资源). Trees provide wood to build homes and furniture. Trees are used to make lots of things around your home and at your school. And trees provide fruits that are good for you. Without trees, the earth would be a very different place.
