tại sao tài nguyên thiên nhiên là vô giá chứ không vô tận ?

2 câu trả lời

vì tái nguyên thiên nhiên là thứ nuối sống con người ,cung cấp cho chúng ta những thứ quý giá như nước,vàng bạc,gỗ thậm chí là cả những thứ vượt ngoài sức tưởng tượng.Nhưng thứ gì cũng có giới hạn của nó nếu sử dụng nhiều mà còn hoang phí thì có to lớn đến đâu cũng sẽ cạn kiệt.Tài nguyên thiên nhiên cũng vậy nó cũng chỉ dùng lại ở 1 giớ hạn nào đó

nên tài nguyên thiên nhiên là thứ vô giá với chúng ta nhưng cũng chỉ dừng lại ở 1 giới hạn nên ta phải giữ gìn sử dụng chúng hợp lí

cho mk ctlhn nếu hữu ích nhé

Hiện nay,như chúng ta đã biết rằng tài nguyên trên thế giới đang dần cạn kiệt do sự khai thác không hợp lí của con người..Những tài nguyên không thể thiêú cho con người chính là gỗ ,nước ,không khí,..nhưng nó đang dần kạn kiệt.Mẹ thiên nhiên đang nhận được rất nhiều những hậu quả nặng nề mà chúng ta gây ra đó chính là :sự ô nhiễm không khí,ô nhiễm nguồn nước ,....Vậy nên chúng ta phải hiểu rằng :'tài nguyên thiên nhiên là vô giá chứ không vô tận'.Chúng ta nên bảo vệ những tài nguyên ấy

Read the passage and choose the best answer (A, B, or C) to the following questions (5 pts) What do you often do after school? In my school, there are a lot of clubs which students can take part in after school hours. The club that has the biggest number of members is the swimming club called “Blue Dolphins”. I myself love swimming so I am a member of this club. I go to the swimming pool twice a day and swim for about an hour. I‟m really interested in swimming breaststroke because it helps me move as fast as I can. I‟m also fond of backstroke. I swim backstroke when I want to relax, breathe and let my body float freely. It‟s very relaxing. The second club I would like to mention is the charity club. Its name is “Golden Heart”. Members of the club often do community service. This month, they are conducting a clean-up campaign to protect the environment around the school. They collect trash, clean the toilet area, and grow plants. I am not a Golden Heart‟s member, but I participate in their activities whenever I can. If you can sing, dance or play musical instruments, the musical club “Heartstrings” is definitely for you. The president of the club is Mike, my best friend. He is not only good-looking but also sings beautifully and plays the guitar very well. In conclusion, we should do as many activities as possible in our free time to have good health and a fresh mind to prepare for lessons in class. Spending all our time studying is not a good idea. 6.
