In the past people could go to travel, live or work everywhere they wanted,(I think it is better to tell "cities were beautiful in the past; instead of travel,live or work....
country's some cities getting worse. People are
go there for
for dwelling migrate because there are some of
problems such as pollution, safety, social interaction among people,
which should be improve
in order to solve
In my opinion, the first problem is air pollution ( why only air pollution, better talk about POLLUTION in general and elaborate it to Noise, air, visual pollution
in the cities. Nowadays, there are an
immense of innumerable
cars and factories which can produce the smog in the cities. It can cause to people in very high level. For example, they can aggravate bronchitis and may even cause cancer. Some people suffer from breathing or other health problems.
(Shady, you can make it one paragraph talking about SAFETY. not only elderly but also young, children and....... people as a whole
Elderly people do not feel safe in their homes. So that is why, people are not going to live or move to the metropolises.
To solve this trouble we have to reduce waste disposals, driving cars, producing less chemicals and industries which are released the worst one. For instance, when coal is burnt in power stations to give electricity, it produces two major gases which cause acid rain.
The second one is unfriendliness ( social attitude and interactions among people
, which is the worst habit in our life. ( is it because of technology, TV, internet , game etc. , you can add it)
When people move to like this place, they feel lonely and some strange. Neighbors do not speak to each other or do not help each other. It is too boring live like these places. In my view, everyone should be more attentive to each other. For example, if your neighbor is new there where you live, you have to help them concentrate on to this place.
To sum up, all countries should be more attentive to their cities. They need to create new places for people who are arriving there and build new houses for people who are moving there.I am not expert in marking but your essay is good in contents. Needs only organizing in clear paragraphs.With Best,
