[MUSIC]. 

2
00:00:05,258 --> 00:00:09,412
You live in a city, you're probably aware 
of this, is that, most cities are highly 

3
00:00:09,412 --> 00:00:13,625
polluted. 
And sensors, could be for example, placed 

4
00:00:13,625 --> 00:00:20,130
on street lamps, poles, in other areas 
and cities at strategic locations. 

5
00:00:20,130 --> 00:00:24,686
To measure the amount of concentration in 
these cities, like if you look at a city 

6
00:00:24,686 --> 00:00:28,970
like Beijing you know, the toxic smog 
seems to be correlated with the 60% 

7
00:00:28,970 --> 00:00:36,663
increase in lung cancer, for example. 
And the reason is that there's been this 

8
00:00:36,663 --> 00:00:41,065
enormous growth over the last few years 
in the percentage of vehicles that 

9
00:00:41,065 --> 00:00:46,035
populate cities like Beijing, cities like 
Mumbai, cities like Delhi, and, and this 

10
00:00:46,035 --> 00:00:53,536
could cause, enormous health risks to the 
human population there. 

11
00:00:53,536 --> 00:01:01,636
So, you're what we envision is the use of 
sensor networks that could significantly 

12
00:01:01,636 --> 00:01:10,880
alleviate these problems by providing 
real time data on pollution levels. 

13
00:01:10,880 --> 00:01:14,662
Types of pollutants, such that, the 
public could be warned to keep inside 

14
00:01:14,662 --> 00:01:19,170
depending on the kind of pollution levels 
that are outside. 

15
00:01:19,170 --> 00:01:23,172
And this If we were to gather enough data 
the sensors could be employed 

16
00:01:23,172 --> 00:01:28,960
intelligently in a city. 
What could happen is that these triggers, 

17
00:01:28,960 --> 00:01:34,620
these alarms could be tailored for 
specific people with specific allergies. 

18
00:01:34,620 --> 00:01:37,790
Specific reactions, specific risk 
factors. 

19
00:01:37,790 --> 00:01:40,474
So that, you know, you don't just have 
this blanket policy that everybody 

20
00:01:40,474 --> 00:01:43,418
ignores. 
Saying that oh, today we have high smog 

21
00:01:43,418 --> 00:01:46,234
and, you know, most people just kind of 
stay, you know, either, you know, just 

22
00:01:46,234 --> 00:01:49,870
ignore it and still, still, still come to 
work. 

23
00:01:49,870 --> 00:01:55,225
In addition to that, if one is able to 
obtain long term fine resolution data, 

24
00:01:55,225 --> 00:02:03,940
this could be used to correlate ailments 
with the population types and level. 

25
00:02:03,940 --> 00:02:10,370
And this could in turn then be used for 
public policy. 

26
00:02:10,370 --> 00:02:14,820
It could also be used to develop better 
tools for medical intervention. 

27
00:02:14,820 --> 00:02:18,900
less harmful pollutants for the 
development of those. 

28
00:02:18,900 --> 00:02:24,080
If we were to know precisely what the 
causation was with medical ailments and 

29
00:02:24,080 --> 00:02:28,668
the type of pollutants that are in the 
air, and these sensing systems can be 

30
00:02:28,668 --> 00:02:36,550
used to do that through communication 
through these vast array of networks.
