There is a lot of reasons why this problem can't be solved for good. One is that there will always be needs from people. The population keeps growing and growing.
The population keeps growing in mainly developing nations. While developed nations are facing demographic problems. Their population is ageing, and the young generation is not willing to produce more babies. In China, Japan and other countries the younger generation are not giving birth due to the high cost of raising children and past government policies.
The resources keeps on dwindling down. Not to mention corruption. Will there be a time where we would all have to literally fight for resources?
The world's resources is enough to feed its entire population. Every day there are discoveries of raw materials in different countries. The issue is that only a few people control the majority of global resources. The fight for resources is already on. If you want to get out of poverty, you would have to fight to get your own share of global resources.
