Question

Explanation:

Selective breeding can be used to develop crops with higher yields, better resistance to pests and diseases, and improved nutritional content. This can help increase food production and alleviate famine. Pollution, global warming, and overpopulation are more complex issues that involve multiple factors such as industrial emissions, greenhouse gas production, and population growth rates, which are not directly addressed by selective breeding.
