If a company has announced that it wishes to build a large factory near our town. To be frank, I have mixed emotions about this.
Obviously, there are some advantages having such a factory nearby. For example, It can provides more job opportunities and many people may work in the factory. What is more, It also gives a good chance for the development of other business in our town such as shops, theaters and restaurants. Furthermore, the products the factory manufactures will improve our quality of living.

On the other hand, there are some disadvantages building a factory here. First, it will disturb the quiescence of our town. Once the factory is set up, a lot of people will rush into our town to work, and the road will get crowded. To transfer the raw materials the factory needs, there will be many trucks coming and going through the streets, and the noise will disturb residents and it is unsafe for our children who always play freely in the streets before.
Second, the factory will produce many waster products each day, and there will be much waste water coming out from the factory and it will pollute our rivers. We do not want to have to see hundreds and thousands tons of waste piled near our houses, and do not want to see our nearby rivers turning into black dishes either.
After weighing the advantages and disadvantages, I decide to oppose to set up such a factory near our town because we need quiet surrounding, blue sky and clean rivers.

But other side, 
I believe that building a large factory near my community has advantages as well as disadvantages. In the following paragraphs I will list basic benefits and losses that will be brought by a new factory.
For several reasons, I think that a new factory will not be a good addition to my neighborhood. First of all, factories often bring pollution. They are prone to contaminating the local air and water. Second of all, factories make noise. Another important aspect of building a new factory nearby is that it will make the local traffic heavy. As a result of this, the amount of traffic congestions will increase, as well as contamination of the air. So, all these obviously will not make one's life happier and healthier in my community.
From the other side, I believe that a new factory will bring some advantages to my community. First of all, it will bring new job opportunities. Many specialists will be required to work there. Second of all, I think many local community facilities will have to be renovated to obtain reliable supply of water and electricity. So, some old pipes may be changed. Another important benefit of this is that the local roads in order to manage the increasing traffic will be rebuilt and widened.
However, I do not think that listed above benefits are worth all these troubles including water contamination and the constant pollution of air. From my point of view all factories must be built far from the people communities because they can be really harmful for people's health.
