In the picture I see two men. One of them is older , the other one is younger. Perhaps this is a father and son. Son sitting on a motorcycle. Motor located on the trolley. The father runs the trolley.
He is walking on water. The water level is quite high. It is caused by flooding. In the background I can see a lot of people and cars. The people in the picture are worried. They try to save his life achievements. For example motorcycle. They lost their homes and are homeless. Volunteers can collect money for flood victims. They can help with the unloading and sorting achievements of the victims. They can organize time for children from flooded areas. On TV I heard a lot of information about natural disasters. For example, a big flood in eastern Australia, the tsunami in Japan, the big snowstorm in the USA.
