There is, of course, a great deal of controversy as to how much the a person's environment affects them. However, it is clear that environment does have an impact on who we are as people.
For example, we know that the way that parents treat their children has a bearing on how they grow up. We know that parents who are excessively protective of their children can cause those children to grow up without a well-developed sense of responsibility for their own actions. We also know that people who are abused as children are more likely to become abusers themselves. These are exmples of ways in which the environment a person lives in affects who they are or who they become in life.
great influence ofcourse, from the people around you. the influence comes from past generations onto people now.
