Copy and replicate
Such dry leaf exchange forum can be setup in other cities as well. You can start it in your own city.

How? Here it is

On individual level
Leaf-donors are all around us. Do you know anybody in your society/ lane who does terrace gardening? Approach them. They will always have requirement for dry leaves.
In Brown Leaf group, many members found their neighbors when they joined the group, where one was burning dry leaves while other needed dry leaves. They were brought together through the group. Now they exchange dry leaves regularly and help each other.
Approach your neighbor who has terrace garden, offer them your leaves. I can guarantee they will be happy to take your leaves.

On larger level
In cities, various garden groups exist. These gardeners are the leaf-takers. Inquire about such garden groups in your city and share the message about leaf availability.
Going a step further, why not start a group yourself, where leaf-donors and leaf-takers can interact?
If you wish to start a group and need my help, I am happy to help. Simply fill in the form below.

Why only dry leaves?

Concluding Words
Keeping our cities clean and healthy is a huge challenge, but not an impossible one. It is not possible for a single person though. We need to collaborate with each other, help each other and together find solutions.
One thing is certain, IT CAN BE DONE
