The kanji 害 is a 形声文字 (keisei moji), a phono-semantic compound character. The character is composed of two parts: 上 (ue - top, above) and 口 (kuchi - mouth). The original meaning of the character was connected to the mouth or food. Then the character evolved to include the additional meaning of something that causes injury. The upper component indicates something that is above, or over, and the 口 is a mouth. This combination might originally have indicated something coming into the mouth that is bad or harmful. Over time, the meaning broadened to encompass harm and damage in general.
