Argumentation:
Firstly, it is important to provide healthy environment. When the trash is not managed well, it will create area where bacteria can live.
Moreover, it can cause some health issues, and breathing issues become one of them that can be caused by bed smell of the trash.
Furthermore, bad management of trash can lead to flood. When it is not managed well, trash can block the flow of water. As the result, water debit can increase during the rainy season and the channels of water cannot deliver the water well.
Reiteration:
That is why it is very important to manage the trash and it is better to promote the recycling process.
Thesis:
There is no best way to deal with pests in agriculture. Pesticides which are commonly used may cause many problems. I think combining different management operations is the most effective way to control pests.
