In some Asian towns an estimated one out of five people wears a face mask. Until you see it, though, that’s just a statistic from afar. In the last five years in Boston, New England’s largest city, I don’t recall ever seeing a face mask outside a doctor’s office.
But sitting recently in a Bangkok café, riding a “tuk tuk” in Luang Prabang, Laos, and touring the ancient temples of Angkor Wat in Cambodia, I saw the reality. We, residents of Planet Earth, have begun to build our bubbles – bubbles protecting us from the world we are polluting.
My journey to Southeast Asia began during Chinese New Year, when millions of Chinese tourists filled the streets. The month before had seen a national health emergency in Beijing – the second most populous city in China. As the city experienced 19 days above acceptable air pollution levels that month, many of them way above, companies gave masks to employees, residents were told to stay home, factories were closed and government cars were ordered off the road.
At the height of the smog, readings for PM2.5 – particles small enough to penetrate the lungs deeply – hit 993 micrograms per cubic meter, almost 40 times the World Health Organization’s safe limit. According to EPA, levels between 301 and 500 are “hazardous,” meaning people should avoid outdoor activity.
Many of the masked tourists were coming off the heels of this.
But the reasons to wear a mask can range from fear of getting sick to fear of infecting someone else to protection from air pollution. On dusty roads masks make breathing easier. Masks are even becoming fashion statements, I read.
The masked included police officers in Chiang Mai, Thailand; construction workers in Angkor Wat, Cambodia, and residents on motorbikes in Laos. And of course Chinese tourists everywhere. All protecting themselves from the world around them.
On the same trip, I visited a village in the mountains of northern Laos where the men still weave bamboo walls for houses, women head to the fields to reap grass for making brooms and night falls in a world devoid of electricity, letting the stars in the sky light the way to the loo.
I am not prone to sentimental musings on sunsets or dewdrops. But confronting so directly the human cost of pollution, set starkly against a backdrop of unspoiled beauty, I greatly appreciated stepping off the plane into Boston, where the AQI was, oh, about 35 on the day I landed.
