The number of hungry people in the world is still rising and very unlikely to become zero by 2030. In 2019, nearly 690 million people were hungry, and an estimated 2 billion people worldwide did not have regular access to safe, nutritious, and sufficient food, although there is enough food on earth for everyone. People are starving in regions where the food supply is sparse or the food too expensive.1 There are many causes for this tragic situation, the most important of which are wars and the growing gap between people who have enough to eat and those who don't. People, including children, often work 16 hours per day but do not earn enough money to sufficiently feed their families. Most of us do not have the power to change these types of scenarios, but we should keep trying and encourage those who can do so. What can be done is to try to make more food available where it is needed. Both producing more and reducing losses may improve availability.
Two of the technologies that may help alleviate the problem are controversial, but we shall try to put them in perspective.
