Yes, you are right. This will be very helpful in educating people who don't have adequate resources. As poverty is one of the major problems we are facing in developing countries, I am hopeful this initiative will help to solve the problem to some extent.
Keeping in mind the existing social media platform where we can share our views and ideas, creating a new social media platform for connecting people who share same values and belief seems difficult from the point of view of sustainability.
But no doubt, if the platform can provide some additional features people are looking for then it can gain the momentum for sustainability.
Looking forward to sharing views on your platform soon.
Best wishes for future.
Your idea seems impressive and yes implementing the same on the local level will definitely change the living standard of local people and solve the problem of hunger during offseason.
Also, engaging youths on other activities like pig/chicken farm can help raising additional fund for them.
