There are many kinds of natural resources on the earth. People use natural resources to produce goods. Trees are used to build our homes and buildings. Oil that is pumped from the ground is made into fuel and other products we use every day. Minerals, such as gold and salt, are also very important natural resources. We can divide the earth's resources into renewable and nonrenewable resources. Renewable resources can be used again and again. Water, soil, and trees are renewable resources. Also, solar power and wind power are renewable resources. They can be replaced within a short time. Nonrenewable resources are the opposite. We can only use them once, and then they are gone forever. Many energy resources, such as oil, coal, and natural gas, are nonrenewable resources. They are limited in supply and cannot be replaced easily. We must conserve our natural resources so that we do not run out of them. 地球上有很多種天然資源,人們利用這些資源來製造商品。 我們使用樹木建造家園和建築物,用地底抽出的石油提煉燃料和其他日用品。金和鹽等礦物也是非常重要的天然資源。 地球上的資源可分為可再生資源和不可再生資源。 可再生資源能夠不斷重複利用。水、土壤和樹木都屬於可再生資源。同樣地,太陽能和風力也是可再生資源,它們可以在短時間內恢復。 不可再生資源則相反,它們被使用一次就會永久消失。許多能源,例如石油、煤和天然氣,都是不可再生資源,它們的供給有限,並且無法輕易恢復。 我們必須保護我們的天然資源,它們才不會被消耗殆盡。 |
