As part of our “throwaway” society, along with our endless desire for new cell phones, it is estimated(估计)that over 125 million cell phones are thrown away every year. Knowing that the landfill doesn’t have to be the end point of your cell phone can greatly reduce the amount of unnecessary waste produced each year.

　　The reason why cell phone recycling is important is that cell phones contain some pretty toxic(有毒的)stuff. But they also contain some non-toxic materials that can be recycled and used again. Yet in reality, we pollute the earth even more by trying to produce these components over again from our limited natural resources.

　　Unfortunately, no landfill is 100% safe. It is the toxins that come from these toxic materials into the ground which pollute our drinkable water supply and affect our health. Currently, less than 1% of the entire earth’s water is drinkable, so we must take steps to protect it.

　　So, before you decide to throw away your old cell phone in exchange for a new one, think for a moment if you really need it or is it because you want the coolest new style? If your older model is still working fine, do you really need to buy a new one?

　　Think about where your cell phone will end up. That it disappears from your sight as it heads for the landfill doesn’t mean its influences stop there.

　　5. The underlined word “landfill” in the second paragraph probably means a place　.
