Why might the worlds food supply be threatened if pollinators become instinct?

If pollinators, such as bees and butterflies, become extinct, the world's food supply would be severely threatened because these creatures play a crucial role in the pollination of many crops and wild plants. Approximately one-third of global food production relies on animal pollination, including fruits, vegetables, and nuts. Without pollinators, crop yields could decline dramatically, leading to food shortages and increased prices. This loss would not only affect food availability but also disrupt ecosystems and biodiversity, further exacerbating the problem.
