While village life has many advantages, including less noise, beautiful natural landscapes, less pollution, fresh air and less congestion, the statistics does not favor the village folks worldwide.Each year, millions of people migrate to urban centers in search of greener pastures. Even though most of them would have preferred to stay in the less stressful villages, they had to move to cities due to economic reasons. Here are reasons why city life is better than village life.
The first reason is transport. The cities generally have well-structured transport network systems that connect virtually all areas of the urban centers. The main modes of transport include road, rail and air. City dwellers therefore have various alternatives when it comes to transport. They may use personal vehicles or taxis on the roads, they may opt for trains to traverse across the outskirts of the city or they may hop into an airplane and go to other cities.There are also paved paths for walking and riding bicycles. On the flip side, villages have the worst transport systems. The main drive way may be well maintained, but other interlocking roads that penetrate through villages and farms are rarely tarmacked. These roads are impenetrable during the wet seasons when they become muddy.Then, there is better communication in the cities. Most communication companies have all their equipment installed in cities, because of the high population which assures them of good return on their investments. They rarely install communication transmitters in the villages, which makes the communication network in rural areas very poor. Village folks have to rely on strong communication boosters from the cities, which are rarely reliable. They therefore have to look for areas with network before they can communicate, which makes the whole process tiring and frustrating. In the cities, communication networks are virtually everywhere even in the poorest neighborhoods.Furthermore, the cities have security. Cities have police patrolling twenty four hours a day. Aside from that, there are CCTV cameras all over the city, which makes it easier to catch criminals and solve crimes. The 911 speed dial also assists in faster response rate from the police force, which is very essential during emergency cases. Due to low population density in the rural areas, the village folks are exposed to a lot of risks.
