Gasping Tiger- Breathing Heavy in India
If you live in an Indian city, every breath you take is killing you. Here's why, and how you can change things...

Even as climate change wreaks havoc across the planet, causing drought and floods, and temperatures in 2016 look set to overtake 2015 as the hottest year on record, a far more toxic problem has been slowly brewing over India's cities in the last decades - air pollution. Its impacts are local and far more devastating to every woman, man and child in India. It does not discriminate with regard to who it kills. We fret endlessly about terrorism and turn against real and false enemies, even as the air we breathe is slowly and surely killing us one breath at a time.
In 2015,The Economist published a short piece on the toxicity of the air Indians breathe. It quoted a World Health Organisation (WHO) report that assessed 1,622 cities worldwide. India had the sad distinction of being home to 13 of the 20 cities with the most polluted air, far more than our economic competitor - China.

Air pollution can't be taken lightly. It is directly responsible for increased levels of stroke, heart disease, lung cancer, and both chronic and acute respiratory diseases, including asthma. It affects the world we live in too, harming animals and stunting plant growth. This is quite different from global warming and rising greenhouse gas levels, where countries continue to defer action and blame each other for the problem. Air pollution in India is a local, not a global problem that can be solved by your city and state governments .
Air pollution is measured as the levels of particulate matter (PM), ozone (O3), nitrogen dioxide (NO2) and sulphur dioxide (SO2). The PM levels are especially important. Depending on their size, they can penetrate through the lung wall directly into the bloodstream, carrying toxins past your natural defences. Especially to blame are low standards for vehicle emissions and fuel and growing numbers of vehicles on the road, low environmental standards for industrial emissions from factories and power plants, poor standards for disposal of waste and household garbage, burning of crops, etc. You see all of these happening around you every day, and each of you undeniably plays a part in this vicious cycle.
In 1988, my teacher, the late Farida Pedder, brought a leaf into class and changed how I look at the world around me. Plucked off a nearby tree in the heat of the summer, it was covered in black soot. I remember her telling us that this is what one year of being in Mumbai could do to a leaf, so imagine what the inside of all our lungs must look like, with a fresh coating of that black, oily muck year after year. The monsoons would have washed that grime off the leaf, but that isn't an option for our lungs. That was almost 30 years ago. I can only imagine how much worse the problem is today.
The WHO estimated air pollution to cause 3.7 million premature deaths worldwide per year in 2012, with people living in low- and middle-income countries such as India disproportionately experiencing the burden of outdoor air pollution. Eighty-eight percent of the premature deaths occurred in low- and middle-income countries. That number will only rise. Take a look at the graph below from the Urban Ambient Air Pollution database ‐ Update 2016. Canada and the European Union set maximum levels for their cities of 30 to 40 µg/m3. Delhi has the worst levels of particulate matter by far at six times the maximum in the developed world. Mumbai and Kolkata, though lower, are still two or three times higher than what is permitted elsewhere.
As India aspires to "emerge" on the world economy, it cannot do so if the very air that Indians breathe kills them. Gardiner Harris' (@gardinerharris) heartfelt column in the New York Times - Holding Your Breath In India - chronicled his own family's struggles with air pollution when they were stationed in New Delhi. He finally decided that his son's health, affected by severe asthma caused by the city's toxic air, was more important that the economic rewards the post offered. This is not just the story of his son Bram, but of every child in New Delhi, or any growing Indian city. Their lives are prematurely shortened and stunted for no fault of their own, leaving them a future of sickness and ill health.
There are also huge economic implications. A very interesting paper published by the OECD in June 2016, titled The economic consequences of outdoor air pollution tries to quantify the economic costs of pollution. Citing the (medical journal) Lancet's, Global Burden of Disease (GBD) study, it estimates that air pollution – indoor and outdoor combined – was the cause of 5.5 million premature deaths globally in 2013. Looking at various impacts of air pollution, including premature deaths, illness, and lost productivity, it estimates that the economic cost for the South Asian and Southeast Asian region alone could be as high as $10 trillion, and take a full 1.25 percent to 1.5 percent off India's annual growth rate. For those of you who think in rupees, that's a very high price to pay in lost lives and prosperity.
For every tough problem, especially those caused by humans, there are always solutions.
Industry needs to be more tightly regulated, and clean technologies should be both incentivised and made compulsory.
Better planning will also reap rewards. Compact urban communities, better energy standards for buildings, urban forests, and near-urban green sanctuaries will clean our air and increase biodiversity and our quality of life.
In addition, prioritising rapid urban transit, walking and cycling networks in cities over the individual's use of a car will reduce pollution, but also increase economic and health outcomes.
Urban and agricultural waste collection must be improved, with open-air incineration prohibited and recycling made the norm.
Lastly, and importantly, as cheap as coal and natural gas are in producing power, what you save in electricity, you pay in lost years of your life. As the need for electricity grows in cities, clean, renewable power is mandatory, and not a nice-to-have.
The fixes are simple, and well within the grasp of our local governments. Inaction is not a solution. If you live in an Indian city, every breath you take is killing you. If you don't ask for action now, there will be no tomorrow.
I often wondered if I should give my 2.4 GHz and 5 GHz frequency WiFi networks on the same WiFi router the same names or different names. The answer is YES! You can and you should. The advantage of this is that it shows as just a single WiFi connection in the entire space, and not two different ones. There is just one login as well. More importantly, your device (if it's not super-ancient) has the sense to figure out which signal/ frequency is the strongest and uses that. If you're close to your router it favours the 5 GHz (faster, but less range) network and if you're further, it switches automatically to the 2.4 GHz (slower, but greater range) network. So go ahead and log into your WiFi router (which for many of you may be integrated into a single box with your modem). If you don't know how, this page helps you to figure that out for most routers. In the settings, make sure the 2.4 GHz and 5 GHz networks are on. Give them the same network names and password
I used it. It worked as promised. In short, the RT LAMP Test Kit @ US$118 / CAD$149 (no taxes applicable) is what all Canadian travellers have been waiting for! Scroll straight to the end of this post for unboxing photos and my experience using the kit. With an overseas trip on the horizon, I researched the daylights out of the announcement from Air Canada and Switch Health that one could buy a molecular test kit in advance that met Canada's entry requirements and saved one the hassle of finding a lab overseas, spending a day getting tested and often waiting days for the result. Switch Health has a video of the LAMP Test Kit online too. The only review I could find left me with questions - it seemed to read like a sponsored endorsement and the reviewer's trip also seemed to have been sponsored. So I'm sharing my step by step journey using the kit, as well as researching and purchasing to help fellow travelers on their own journeys. See the end of this post for unboxing ph
Most importantly, you can use Vonage Canada 's services on Beanfield Metroconnect 's network in Toronto. If you use Vonage 's services in Canada and are switching or have switched to Beanfield Metroconenct 's awesome service in Toronto, here's how to configure the router to allow Vonage's services to still work. Since Beanfield is a local service, Vonage's (helpful) tech support had no idea how to help me navigate the hardware, as they would have if I'd been with Bell or Rogers. Log into your Beanfield router. Beanfield uses a proprietary optical fibre router. If you don't know how to, call or email Beanfield's (helpful) support and they'll tell you. Once you log in, choose the "Zhone Router Rental" and click on it. Then choose the "Port Forwarding & Firewall" tab, and choose the "Add Rule" button on that page. Add a rule with information to get the outcome in the image below. Description: vonag
