Transportation that is more than our feet have been once of mankind's greatest achievements in the history of the world and beyond. With the use of transportation people and cargo are delivered from Point A to Point B in much shorter time than it took a walking human to do to reach their destination. Indeed, without transportation humanity couldn't have reached its peak as a global network and a financial powerhouse.
Much time can be saved with transportation, but no matter how many artificial islands shall be created – the land of the world is limited even if expanded. So is the threat on it by a growing mass of private transportation – every vehicle that is within a private citizen's ownership. With the massive growth of human population and with the increasing involvement of driving-able citizens joining the ranks of veteran drivers – more traffic jams are created, making the time to reach point A to point B extremely large, and with more cars produced so there are more hazardous chemicals polluting the world and decreasing our heath and life expectancy. In some countries it has come to people's inability to go outside without protecting their nose and mouth, such as in India, China, Japan and South Korea.
During sometime there was a chance for a solution to this problem at least partially, by using cars that consume electricity instead of oil. In 2007, an Israeli corporation named Better Place was about to revolutionize transportation by creating proper infrastructure for electric cars around the world, such as recharge stations. However, it was disbanded in 2013 due to lack of fund. Even if this corporation would've succeed and prosper internationally, it would only solve one problem – the problem of damaging the quality of the environment. It wouldn't solve the other problem which is a gradually-decreasing space for roads across metropolises, where most of humanity resides.
This is why public transportation needs not only to be more invested by governments worldwide, but to be encouraged as well to be used as much as possible. Even if it may take some of your personal time and even if there's no privacy in the bus's internal space, it can not reduce the output of unhealthy chemicals into the atmosphere, but is also much cheaper than getting a license, buying a car, maintaining it and fixing it altogether, and let's not talk about the issue of parking lots – with public transportation you can save much time from searching extensively after an available parking space to bring you out of your misery.
There should be more buses, and they should be used not only in metropolises but across metropolises. In a world where public transportation becomes the norm, there would be less traffic jams, people would be healthier, and the environment would be damaged less, increasing our well being and reducing our modern tensions.
Private transportation, on the other hand, should be less encouraged. Even if it brings you independence, your car wastes space on traffic that otherwise could've been used by more passengers. One can estimate that a bus is at the length of three cars, and each car has 1 to 4 passengers. A bus, however, can have few dozens of passengers. If the dozens of passengers would drive a car instead, the sum of their cars could be at the length of a few buses. That's very wasteful, if you ask me, and I don't even plan to get a driver's license, because I prefer to contribute to the traffic by letting only myself in the traffic, and not an entire car with 2 or 3 empty seats.
If more people will contribute to traffic by taking public transportation more often, there will be a natural demand for governments to invest more of their resources on their departments of public transportation. This pressure will reduce cars and could encourage the manufacture of more buses and more maintenance for the buses. Even if governments will have to pay more to get things done, it may even benefit them in the long run, by having to worry less about the creation of new roads and the expansion of existent ones.
In the far future it may even be inevitable BUT to use some sort of public transportation, because there will be less space left to build roads on, and with more cars in traffic it would take even longer to reach one's destination, to the possible point that you may be able to reach your destination much faster by walking, which is by itself a good solution for proportionate distances and good for your health and wellbeing.
Don't get deluded by the speed and the attractiveness of new cars on the commercials – in reality you may spend a significant portion of your day waiting in traffic jams. There's no need to boast about the luxury of an expensive car – it waits on the traffic jam just like an old one. Sacrifice your privacy for the sake of the destiny of the world.
