Can apps create pollution?

It is a question that does not cross our mind very often.
Apps on our phones are very useful in our day to day lives. Everything that we require is just a tap away.
Our entire life revolves around these applications. From groceries to cabs to food to anything that you need to buy, it’s all just a touch away.
They say, the only thing that is constant is change.
Since the last couple of years there has been an exponential increase in the number of vehicles in my city.
I don’t know the exact reason for this sudden boom in traffic which can be anything ranging from getting rid of black money by investing in cars or boom in business due to the economic growth of the country, to buying cars to earn money from applications introduced on our phones like Ola, Uber etc. 
In the olden times, the pre – cabs that you can call using your phone times, – people used to use more of public transport and the only cabs that were available were the regular ones where people had to get out of their houses to hail one.
Although nowadays things have changed for the worse, because now people can just sit at home and book a cab. All they have to is move some fingers and voila! A cab at your door! 
Even if they have to pay more for it they still avail it because that way they can avoid doing more work and get to travel in an air conditioned car.
Where there is demand there is always going to supply and vice versa. It’s a circle. Here, the demand is ever increasing and so is the supply of cars. People are buying cars and renting it to big taxi companies. There is a lot of profit to be gained by supplying cars to these companies. 
So as the number of cars keeps increasing, the amount of pollution in the city is also increasing along with other stuff like bumper to bumper traffic jams, no parking spaces which has led to the previously empty roads to become a hotspot for parking cars. Maybe there will be a time where people will have to stand in line to be allotted a space or they will start a fight, right there.
To be honest, I sometimes feel that the new generation might not even be able to imagine the idea of empty roads.
I personally know a lot of people who used to use public transport but now have completely shifted to online booked cabs. These people just won’t travel any other way. They will straightaway refuse. Why? Because apparently it lowers their status in the society. Somehow availing an app based cab who charges way more than a normal cab is a style statement. 

The more people use these cabs, the better foothold these companies get in our markets. Once they capture our markets their fare prices skyrocket and there is nothing that we can do about it because there is no other alternative to avail.
If people use more public transport it would reduce the daily carbon emission of the city. It would also save people a lot of money and eventually the amount of traffic on the roads would gradually drop.
People would be able to breathe cleaner air and probably won’t die of lung disease.
