In addition to the beautiful environment, modern technology is also very advanced. All kinds of robots can handle all kinds of garbage, sewage and waste gas, turn waste into treasure, and even solve the problem of human water shortage, make useful daily necessities for human beings and make human life better.
10 years ago, although the roads in my hometown were wide and flat and there were many tall buildings, the greening was really poor, with white garbage everywhere and greenhouse effect. Now, all kinds of manufacturers follow our hobbies and produce a lot of soft drinks. The "coat" of soda is cans, and roads, parks and even schools have become their homes. But the main raw material in the jar is aluminum, which does more harm than good to the human body.
You see, how happy we are now living in such a good environment! How worth cherishing and protecting! Therefore, we should carry out environmental protection to the end, so that our hometown will always maintain that natural beauty!
