Answer:
The Food Problem:The global food problem consists of the lack of food provision for the Earth's population. It manifests itself primarily in the poorest countries of the Third World and is currently aggravating as their populations grow.
Two Ways: The food problem can be solved by planting trees. In the world, there is (more than) 2 billion hectares of degraded farmland available that once was covered with trees. Trees have and can grow again on this land. If we plant these areas again with trees that produce food, we can solve the food problem!!
