I have been asking my self the same question from day one here on Steem.

I can try to help us answer it by asking:
How can fiat money help such a project?

Well, in our case not so much, we dont need money to rescue food waste and the food its self is the motivation to spend time and energy to collaborate around a foodsaving project.

My idea for our project here on Steem is to:

1. document the project on the blockchain (proof-of-human-work)
2. inspire others users (who are already open minded to change) to do something about a global food waste problem, and to show how simple it really is.
3. experiment with crypto tokens to further grow the project like;

• funding for developent of the https://karrot.world/ platform
• use tokens to pay for online services (website, domain or email)
• start using crypto instead of fiat between projects with similar values, (sharing economy) both local and global

Let me know if this makes any sense for case.
