<正>How many electronics and electrical devices do you use daily?Cell phone,computer,TV,earphone,smartwatch,electonic toothbrush,refrigerator,washing machine,water heater,E-reader,just to name a few.They’ve played a big role in our lives,sometimes a life changer(cochlear implants,etc.for people with disabilities).New e-devices constantly emerge with the advance of technology,replacing the old ones,either broken or still well-functioning.Do you ever think of what happens to them after being dumped?
