Great, now I have to worry about this every time I order a curry

About to be the only reason anybody looks into North Dakota.

It would be simple for smart phone manufacturers to have an air quality tester built into the phone. Everyone being able to measure how crappy the air around them is and be notified when it’s unhealthy would push action on environmental care, reduction in cars etc

Google of course, being one of the biggest polluters on Earth, knows that Real Recognizes Real.

Creating and parsing this data set would also create a shitload more carbon emissions and necessitate building more datacenters, wouldn't it?
