Water is the most important substance in our evolution and our daily lives. Without water‚ life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earth’s successful ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom bears a slight electronegative charge while hydrogen possesses a more positive one. Because opposite charges attract‚ the
