Hunger has become a serious problem in many parts of the world. The first cause of hunger is the fast growth of population. The Earth is no longer able to feed its more than seven billion people. There is not enough land for growing food. The change of climate also brings to the Earth more weather-related disasters such as storms and droughts ... They heavily destroy crops. Wars are still happening. People are fighting, or running away from home. There’s nobody to work on the field or in the factory to produce food. Technology is working hard to help solve part of this problem. In the future, we will have warning systems to reduce the loss from natural disasters. Low-cost means of transport will also be used to carry food to area-in-need. 1.
