here is the world in 2011:
so more human impact, more resource usage and wastage
want to talk about resource wastage?
we are currently in ecological deficit:
while the world is producing enough (3Kcals per day), the redistribution of food remains a pipe dream due to prohibitive costs, no perishable storage, political boundaries and total lack of applicability in all dietary metrics.
let me give you an example: india has a mango suprlus. but the problem is that mango needs to be consumed as a tropical fruit.
USA has a meat surplus while Bangladesh and India are the lowest consumers of meat because they are primarily vegetarian. naturally weather and environment play a large role in applicability and nutrition.
blockchain will solve many technological problems but it will not solve world hunger or social inequalities.
blockchain is a technology with the potential for a vast footprint. It is however a technology that can be controlled by a few people. i think that discussion is for another time.
i sincerely hope that blockchain will solve the world's resource scarcity problems but there is no evidence today to show that it could be possible.
