Final answer:
Human societies have implemented solutions to world hunger that can create additional problems. 'Risk-free' solutions currently being promoted include social protection programs and support for farmers, but they may also have limitations.
Step-by-step explanation:
Human societies have responded to the problem of world hunger by implementing solutions that may create additional problems. This is supported by the fact that differences in technology, capital, and labor across countries contribute to international inequality. Solutions to world hunger often have unintended consequences. For example, industrial agriculture and monoculture operations used to increase food production can lead to environmental degradation and reliance on finite resources.
Currently, 'risk-free' solutions are being promoted to address world hunger. These include measures such as social protection programs, support for small-scale farmers, food distribution programs, and education. However, even these solutions may have limitations and potential drawbacks.
