Nowadays, large cities are becoming more and more inhabited. The majority of the population prefer living in a big town mainly because of the great advantages it has compared to living in the countryside. However, what are the benefits of this situation, and what are the drawbacks? In this essay, I will explore the pros and cons of living in a large city and try to draw some conclusions.
Let’s start looking at the advantages. One of the main positives of a big town is the large amount of shops available in every corner of the city. What I mean by this is that whenever you live, there are some useful stores supermarkets, banks, tobacconists and clothing stores where you can easily buy everything you need without going to the city center. Secondly, living in a big town is a big challenge for evening parties. In London, for example, there are so many things to do in the evenings going to the cinema, to the pub or to the park during the summer period.
Turning to the other side of the argument, traffic could be one of the major disadvantages of living in a big city. Many people take the car everyday and it has also been proved that the majority of the families have at least two cars. This means that you have to deal with rush-hour traffic on your way to work and on your way back. In addition, in a big town there is consequently a lot of smog and this can really affect people’s health.
To sum up, living in a big city has great advantages but also some significant negatives. You have to weigh up to the pros of enjoying evenings’ nights outside and the availability of many shops and the cons of cope with smog and traffic issues. Personally, I believe that the benefits of enjoying the city-life and the comfort of having shops at every corner, eventually overweigh the negatives.
Protecting the environment includes the indoor environment and indoor air quality. One way to protect the indoor environment is not to bring indoors any products with surfactants in them. This means switching to safe, non-surfactant cleaners and laundry products. Another way of protecting the indoor environment is not to bring in grooming products that contain phthalates or other volatile organic chemicals or persistent organic particles in them. This means switching to safe, phthalate-free and VOC/POP-free grooming products. This also means switching from manufactured "perfume" fragrances to natural essential oil fragrances, the original perfume material.
Another way is not to bring in bleached recycled paper or plastic products. This includes most food packaging boxes, even organic ones (except for those that have switched to non-bleach/chlorine recycling process products), most meat and poultry trays and plastic wraps, most egg cartons, most ice cream cartons, most recycled school loose-leaf and notebook paper, most plastic bags. Another way is not to walk into the house with your shoes on. The EPA has determined that more than 50 percent of indoor air toxicity comes from petrochemical particulates tracked onto carpets from shoes (worsened when shoe soles are constructed from petrochemical based materials).
Draconian, drastic measures are needed to protect both the outdoor environment and the indoor environment. If our mega-scale free market system worked, we could demand unsafe materials be taken out of production and easily improve indoor air environments, but it doesn't, and we take what we are given while advertising campaigns convince us that what is given is great and the best and that which is what to covet.

There is no denying that computer is one of the all-time greatest inventions of human being. It has brought us an endless number of benefits. This miraculous tool not only allows us to edit documents, to create excel worksheets or to install programs to serve our needs but also helps our kids relax with a wide range of games and apps. However, some people believe that computers may bring more harm than benefits if children use them daily; meanwhile, others state that they are helpful and can affect children positively. In my opinion, I totally agree with the first idea because of the following reasons.\nTo begin with, children will be isolated from other people around them if they use computers frequently. It’s simply because they spend most of their time on utilizing computers, so they do not have much communication with their parents. Moreover, when computers become their close friend, they may refuse to play with other kids as well as to take part in outdoor activities. It means there is less interaction between them and their fellows. Obviously, this is not recommended for children since they need to be active and to learn new things from family and friends to broaden their horizon. \nAnother point is that using computers uncontrollably may cause children to develop some diseases. Sitting in front of the computer regularly may lead to obesity because every day, children absorb a large amount of nutrition such as fat, protein and starch but they do not take exercises to consume this energy. Seriously, obesity can put them at higher risk of developing diabetes. Besides, some research has shown that looking at the computer screen continuously with concentration more than 2 hours will reduce our vision and cause myopia easily.\nThe last reason is that children can neglect their study and sink into computer games. It goes without saying that computer games are so addictive. If kids are unable to control themselves, they may spend all their time on playing games. After completing a level, they will have promotion to continue to play and to unlock new levels, then all these things will be repeated over and over again. In addition, computer games can inhibit the ability of thinking of children because they do not need to rack their brains a lot when playing games. Consequently, their study results may become worse and this will affect their future significantly.\nIn conclusion, I am totally in agreement with the idea that using computers daily will put great negative impacts on children. However, they can still take advantages of this wonderful invention if they use it suitably and effectively. Therefore, parents should teach their kids to be self-disciplined and to manage their time well when using computers.
