How do you express your gratitude?
If I can do my part in making the community or society a better place emotionally and physically by talking or recycling then the others may follow. Of course it would be better if everyone was incentivised but probably in the beginning will be at a loss.
But do things that make you feel good, like what you are contributing to the community. This can come in the range of talking (giving knowledge) or paying for goods and services and recycling and reusing when you can.
I cannot rest until, everything and everyone is turning around intangible or tangible things but how I see it is like money because money flows in a range of goods and services just like when money flows to you when you offer goods and services. I do not do it all for me but for others well being as well which we should give back to society.
