You can speak to people on other side of the earth over the telephone with help of a satellite. They can help to take photos on the earth and produce maps. Some pictures taking by satellites show us the exact place where different metals can be found. They can also tell the differences between healthy plants or poor ones. This is a great help to the scientists work in forestry and in agriculture. Satellites benefit by out daily life. For example, satellites for broadcasting are used to sending radio and TV programmes from one part of the world to other. It is the satellites to make our world seem smaller.
