This artist vacumned the air in Beijing for 4 hours each day for 100 days and created a brick.
When I was in Beijing, I was shocked at the pollution. I had never seen such thick gray air. We all wore face masks, coughed, and became rather sluggish. But finally, the winds came and blew the polluted air away. The city was then transformed, and so were we. Clean air makes a big difference to how you feel about a place. It also is vital for your health and wellness.
