Using my on tumbler whole day

With the campaign that ASEZ WAO started, I used my tumbler again. Recently I was familiar with the plastic cups that can be used for only one time again.. But with the campaign, thankfully, I opened my eyes again and realized I am doing such a wrong action and started to use my tumbler again. Now I feel much better and feels like I am doing something that this planet will feel much comfortable. Let’s try to use our own tumbler and save this planet together!
