This week we don't print cinema tickets and checks at an ATM, and do not use note papers at all. Potentially, this is 7 checks, 7 note papers, 2 cinema tickets for a week. We can keep all this stuff on our phones. It's a trifle, but good for nature.
Challenge #18
While accepting the challenge, we'll save 15 g of trash per week.
That is 1.5 kg, if at least 100 people accept it
