I throw away stuff in designated trash cans but beyond that I don't see how I can help further.
And I don't mind effort, at all. I go the extra mile at home to use less kitchen paper. I use less chemicals to clean around the house. I reuse phone and tablet chargers, and headphones. I don't buy new computers often (current PC is 8 years old now).
I try and be disciplined. But I am no sewage treatment plant, or a plastic/metal melting foundry so I do what I can but not sure I am helping at all.
I think many people misunderstand me in my bigger comment in this post: I try and help but (1) there's a line beyond which you are slaving yourself to supposed improvements you cannot see and so it becomes not worth it, and (2) I am asked to trust other organizations that if I throw away stuff in special areas then I am helping the planet. I don't mind #2 -- it's better than nothing. But I can and do mind #1 here and there.
It's not such an unreasonable stance as many make it look.
