In our daily life, most people use disposable plastic bags for shopping and other purposes. However, the excessive use of disposable plastic bags has resulted in a great damage to our environment.

　　The problems brought by disposable plastic bags are various, ranging from environment to people's health. In the first place, it takes years for the plastic products to decompose and be absorbed by the soil. Secondly, the use of disposable plastic bags will indirectly do harm to people's health. Sometimes people buy hot food packed into disposable plastic bags for saving time to wash their dining utensils. Yet they are not informed of the chemical material the bags release in high temperature. Therefore, they are also eating the poisonous stuff while enjoying the tasty food.
