What does agriculture have to do with world hunger?

To answer your question, there would be a lot more world hunger than there is now. If places that suffer from hunger were to teach the people agriculture, they could start subsistence farming and that would help end world hunger, though of course we can't tell if it will stop it completely. Agriculture basically refers to farming, so this is where all the crops that feed the world come from. More agriculture should theoretically stop world hunger as everyone would have enough food (although this wouldn't actually be the case as the Western world has 80% of the world's total food resources).

Agriculture plays a crucial role in addressing world hunger by providing food production and distribution systems. It influences factors such as food availability, access, and utilization, which are essential for addressing hunger. Agricultural practices, including crop production, livestock farming, and fisheries, directly impact food supply and prices, affecting food accessibility for vulnerable populations. Sustainable agricultural development also contributes to food security by increasing yields, improving nutrition, and enhancing livelihoods, particularly in developing countries where hunger is most prevalent. Additionally, agricultural innovations and technologies can help mitigate the effects of climate change on food production and ensure long-term food security for the growing global population.
