The war involving Iran is starting to affect the global food supply. This is because fertiliser, which farmers need to grow crops, is not being produced and shipped properly. Svein Tore Holsether, the head of a big fertiliser company Yara International, said that up to 10 billion meals per week could be lost because of this problem. The conflict has blocked ships in the Strait of Hormuz, an important route where many fertiliser materials pass through. Without enough fertiliser, farmers may grow less food. In some cases, crop production could drop by up to 50%. Poorer regions like Africa, Asia, and Latin America will be affected the most because they already struggle with limited farming resources. Some countries may not be able to afford higher food prices. Experts warn that if the situation continues, richer countries might start competing to buy food, making it even harder for poorer nations to get enough. Even in places like the UK, where food shortages are unlikely, prices are expected to rise soon. Globally, millions more people could face hunger if the crisis gets worse.
