The first grade talks about the changes before and after air pollution

Changes before and after air pollution, when I was a child, the river behind my home was clear, so I could take a bath and swim directly, but now it is mixed; Before walking on the sidewalk, there was no serious smell of automobile exhaust, but I couldn't get out without a mask. When I was young, the sky was blue. Now the sky is sky blue, so take a photo with your camera and bask in your circle of friends!

The changes before and after air pollution are too great. Although everyone has a sense of improving air quality, the improvement of air quality cannot be improved in a day or two. Although we can't change the outside environment, we must pay attention to the indoor hygiene of our home. I pay great attention to indoor air quality. After consulting online for a long time, I chose a five-degree air conditioning system, and my cough gradually improved in foggy days. In addition, I can see the indoor air quality index every day, which is in a healthy range and makes me feel at ease. You can search Baidu. I wish you good health and hope to adopt it.
