Street Foods
Street foods can be seen anywhere. Although it is the nearest place that we can run when we are really hungry, it is not safe. This is where we can different kinds of sickness which are transferred through ingestion. When we eat foods in the street, sometimes we are not sure if it is clean or not. When the foods are sold on the sidewalk, sometimes, the dust or smokes coming from the vehicles are flown to the food. We are also not sure if the utensils they use are clean or not. When there is a sauce, sometimes people are not contented with one dip. After biting their food, they still dip it again which may leave bacteria to the sauce. For example, if a person having hepatitis eats there and dips the food he is eating again and again, the virus will be left to the sauce. When the next person dips there, his food will be contaminated and the person will get hepatitis already. We should always take good care of ourselves. We should always make sure that the food we eat is clean and safe. It is better to buy foods with high price but clean rather than cheap foods and pay a high price for hospitalization.
Why are Children More Susceptible to Air Pollution Than Adults?
In many health effects research studies, children are considered as if they were small adults. This is not really true. There are many differences between children and adults in the ways that they respond to air pollution. For example, children take in more air per unit body weight at a given level of exertion than do adults. When a child is exercising at maximum levels, such as during a soccer game or other sports event, they may take in 20 percent to 50 percent more air -- and more air pollution -- than would an adult in comparable activity.
Another important difference is that children do not necessarily respond to air pollution in the same way as adults. Adults exposed to low levels of the pollutant ozone will experience symptoms such as coughing, soreness in their chests, sore throats, and sometimes headaches. Children, on the other hand, may not feel the same symptoms, or at least they do not acknowledge them when asked by researchers. It is currently not known if children actually do not feel the symptoms or if they ignore them while preoccupied with play activities.
This probably does not mean that children are less sensitive to air pollution than adults. There are several good studies that show children to have losses in lung functions even when they don’t cough or feel discomfort. This is important because symptoms are often warning signals and can be used to trigger protective behavior. Children may not perceive these warning signals and might not reduce their activities on smoggy days.
Children also spend more time outside than adults. The average adult, except for those who work mostly outdoors, spends most of their time indoors -- at home, work, or even at the gym. Children spend more time outside, and are often outdoors during periods when air pollution is at its highest.
The typical adult spends 85 percent to 95 percent of their time indoors, while children may spend less than 80 percent of their time indoors. Children may also exert themselves harder than adults when playing outside.
Perhaps the most important difference between adults and children is that children are growing and developing. Along with their increased body size, children's lungs are growing and changing, too.

The Lung's Important Role in Health
The lung is an extremely complex organ. While most organs in your body are made up of a few different types of cells, the lung contains more than 40 different kinds of cells. Each of these cells is important to health and maintaining the body's fitness. Air pollution can change the cells in the lung by damaging those that are most susceptible. If the cells that are damaged are important in the development of new functional parts of the lung, then the lung may not achieve its full growth and function as a child matures to adulthood. Although very little research has been conducted to address this extremely important issue.
Garbage in our environment
Garbage is everywhere. Anywhere you look there is garbage. I don’t know why people can’t just prevent themselves from throwing trash anywhere. The streets are like one big garbage can. We could get sick because of this. The scent that is being carried by the wind we smell could endanger our lungs. The juice that comes out from the trashes could go to our water system. And also, it is not pleasant to the eye. It is a shame if tourists will be disgusted with the way our streets look. If we just prevent throwing trash anywhere. There are garbage cans or bins available. We could make good use of it. Also, not all garbage is with no use. We could make other better things with trash.
