Express yourself
Online shopping is becoming more and more popular. However, it produces lots of unrecyclable packaging. What solution do you have to this problem
Possible version:
I think as a consumer, we should choose to buy from the stores that use more recyclable packaging materials. We can also try combining orders and requiring items to be shipped together. I also suggest the online shop owners take packaging waste into consideration. They can give a packaging option that items are delivered with easy-to-open, recyclable packaging without any additional boxes or envelopes even on some additional charges.
