We will suffer from a want of food. The global warming will change the climate of the earth as never before. That means some places have more rainfall and the other places have lesser rainfall than before; therefore, the danger of flood damage and lack of water will be more seriousness. It will also affect the farming and the fishery a lot. The production of provision will extremely decrease and the change of current will cause a shortage of seafood. Many people who live in a poor country already starve to death. If the climate changes, they will be more hunted down. Besides that, Japan imports a lot of foods form other countries. If that countries are affected by flooding or drought and their productions of eating reduce, they will not sell provisions to Japan. We will not able to get enough foods if the global warming gets worse and we may scramble for them.
This is what is happining in Africa......
