Are 33 a. Nowadays, cellphones have become a necessity in our lives. However, like other manufactured goods, they can be expensive (1) when broken. Considering how fragile some cellphones can be, they are usually used for a short period of time before being discarded without a second thought. They are also replaced as soon as new models become available. These factors have huge environmental consequences, which can only be effectively (2) by recycling. 因 完被 Ith 丟棄。 (3) has been repeatedly proven that tossing away unused electronics 再被證明 丟棄 不用の 電子產品 harms the environment. When burned or buried, the metal, plastics, and the 燒 掩埋 chemicals in cellphones release (4) pollutants into the land, water, and 釋放 污染物 +441 air. Once they're in the environment, they could cause serious damage to plants, animals, and eventually us. Furthermore, the resources needed to produce cellphones are obtained through mining, deforestation, and 採礦 砍森林 industrialization, all of which destroy the environment. 工業化 破采 These problems can be avoided (5) we recycle unwanted cellphones. Hopefully, by using recycled materials, we can better protect Mother Nature 但原願 in the age of consumer electronics. 材料 C2 De 2. (A) clustered 1.
