Well you know, that is in Africa so things are different yes. The people dont think though to do it willingly though like people do in other places around the world, which is also quite strange, but well it is just a completely different world but still on the same planet :)
Once the Chinese have developed Africa in the up and coming years then they too will have full 5G (which i'm not a supporter of) also and can get more involved with blockchains like this one, and exactly just like this initiative right here we can help the common person and the planet at the same time!
I don't think people in Africa are less willing to fight pollution than on other continents. I believe the major difference is that they are lacking a proper infrastructure. Here in Germany we have a local administration that takes care of garbage. Many countries don't even have that.
I also heard that cryptocurrencies are well suited for less developed countries. Even getting a bank account is hard in some places and only very rich people can. Using crypto is actually easier for them.
