The only real solution is to reduce the population. Look at the countries which are facing famine and hunger. Most of them are located in the Sub Saharan Africa and the middle east, where the population growth is above 3% per year (i.e the population is doubling every 20 years). I am talking about countries such as Afghanistan, Yemen, Niger and Somalia. These nations need to practice population control.
Every country used to have a big growth in population. As the countries develop, this decreases. It is due to the rapid increase in medicine in their country. When they had children, chances of them never reaching adulthood were very high due to many diseases, so naturally this is counteracted with having more children. It is not a problem for starving since it is a self-correcting mechanism and the balance is always reached. The problem is in the irregularity in their food supply, so that either has to be fixed or they need to be provided to move at any time.
we have fixed number of resources so that we cant solve this problem
This couldn't be farther from the truth. Not only can we make a lot more food, but we already make a lot more food then we eat. A huge portion of food that is bought is thrown away in the developed countries, even tho they still eat more food than they should, let along need. The problem could be fixed by tomorrow if we really wanted to, it is just that we want to make sure that the solution is long term.
Though small-hold farmers produce the majority of the food we eat, they are also more vulnerable to factors beyond their control: climate change, failing seeds, volatile markets and infectious crop diseases. But a new peer-to-peer service, known as WeFarm, is using a simple form of social networking to help them stay informed
I don't see why you need a coin for that. Seems just like another useless altcoin. You can solve that with a simple facebook group if you really wanted to if the lack of information is the whole problem. You can use a decentralized social media software if you want to make it decentralized as well. No real need for a cryptocurrency.
