Kimchi is a traditional food served in South Korea. The main part of the food is a preserved vegetable, often cabbage. But this year, Kimchi is more costly than usual because the cabbage crop has been small. Some farmers say climate change has made it harder to grow cabbage. Temperatures have been high and there has been more rain than usual. Businesses that sell kimchi are having trouble making money because there is less cabbage than most years. Their costs for cabbage doubled over just three months this year. Cabbage prices reached their highest level in 24 years last summer. In addition, kimchi is getting more popular around the world so there is more competition.
