The change in air condition is always very obvious and perceptible to us. The first few days of this week, most of us should have felt Vancouver covered by mountain fires, the sky looked grey, and the weather forecast on our phone reminded us that such weather could even affect our health. The air quality in China has changed a lot in the last decade; I remember the air quality data long ago was five times worse than now; even so, the current data of pm2.5 and other pollutants data are still very far from our Paris Agreement goals.
I envision a very airy, clean, and fresh world. So that people can breathe fresh air and not have to wear masks when their air quality is very bad. At the same time, they can work and exercise outside without any worries. We should consider why the frequency of mountain fires is increasing and whether it is because of abnormal environmental changes and global warming. We should push for more government policies to protect forests and support new methods regarding sustainable forestry and fire control.
