Living in a big city is difficult, but it also has many benefits. The benefit is that we will have a more modern and our living space. There will be restaurants big enough for us to interact and party as we please without being disturbed. But through that there are also many limitations or on the other hand called the difficulty of living in the city. There are a lot of difficulties like not being able to find a favorable long-term job while in the city leading to unemployment. There is a lot of street smog, especially atmospheric pollution, ... If you want to live in the city there will be many beneficial and harmful sides. In the countryside, the conditions will not be like the city, but still have a fully equipped life, but not many difficulties.

Nowadays, more and more people choose to live in the city. In this essay, I will discuss about the advantages and disadvantages of living in the city.

It can't be denied that living in the city has many benefits. First of all, if we live in the city, we will have many chances get the developing science and technology. It means that we will have more job opportunities and broaden our knowledge more easily. Secondly, we will have many different ways to spend our free time. There are a lot of theatres, concerts and other kinds of entertainment. There is always a lot to do and visit There are a lot of possibilities of shopping. In various shopping centres and galleries you can buy whatever you want. What is more, a big city is a potential market for trading activities, so we can earn more money to provide our family a comfortable life

Besides advantages, living in the city brings to us a lot of disadvantages. Firstly, a problem about which everyone is worrying is environment. The increase of factories based on industrialization and modernization has severely polluted environment. Smoke from factories' chimneys not only pollutes the air but also makes people get many serious cancers. Sewage is bumped into rivers without being purged, which threatens underwater ecosystems. The second drawback of living in the city is society's vices such as drug addiction. Young people. especially the students, are easily spoiled by bad habits. If people use up all the money, they can't control themselves and even become robbers or murders. Moreover, a problem that many people living in the city have is heartlessness. With some people, it's not worth being worried and it has no effect on our life, people are too busy to care for any others. But if more and more people become heartless, the society will be worse, no one cares another one, they live boring lives, every purposes became meaningless, without love, sympathy and many other good things.

There are good things as well as bad thing of living in the city. However, I strongly believed that advantages outweigh disadvantages. If people know how to live and enjoy their life, living in the city is one of the most interesting things that people want to experience.

Fresh water is the most important source of life on the earth. Any living thing may survive without food for days however it is impossible to imagine life without water and oxygen. The ever increasing human population enhances the demand of more water for purposes like drinking, washing, performing industrial processes, irrigating crops, arranging swimming pools and other water-sports centres. Water pollution is done by the people of all over the world because of increasing demands and competitions of luxuries life. Waste products from many human activities are spoiling the whole water and decreasing the amount of oxygen available in the water. Such pollutants are altering the physical, chemical, thermal, and biological characteristics of the water and adversely affecting the lives inside as well as outside the water.

When we drink the polluted water, harmful chemicals and other pollutants goes inside our body and deteriorates all the body organs functioning and puts our lives in danger. Such harmful chemicals also disturb the lives of animals and plants greatly. When plants absorb dirty water through their roots, they stop growing and die. Thousands of seabirds are killing because of the oil spilling from ships and industries. High level of water pollution is done due to the chemicals coming out of the agricultural usage of fertilizers, insecticides and pesticides. The effect of water pollution varies from place to place upon the type and amount of water contamination. The degradation of drinking water needs an urgent basis prevention method which is possible by the proper understanding and support from the end of each and every person living on the earth.
