破坏= to break something down on purpose 损坏= something is broken by you unintentionally 损害= Something you did or your behaviors will hurt someone's feeling or damage their property. Anyway, it stress the consequence.

In basic, all are similar to each others because they are meant "somethings become worse or demaged" at all. Here some series of explanations of meaning and examples for your reference! * 破坏= break down; destroy; Example: Wood-cutting destroys the natural environment. Please stop! * 损坏 = demage; impair Example: My father's hearing was impaired by an accident. * 损害 = injure; damage; loss Example: Over-smoking has injured your health! Hope you quit smoking from now on. Hope these make you clear more!
