How does the environment you live in affect who you are as a person?

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.
