The overall idea of defining your family as a part of your environment is fine, but your way of introducing the idea is, as Simone said, contradictory. This is the logic you have at the moment:
Environment is mostly the people around you.
I had great family and friends in Ethiopia.
They all wanted to leave for California.
So, I was in a great environment, but wanted to go to one in which I knew no one (i.e., a bad environment).
We know what you mean, but you have to explain yourself better, which will involve referencing other elements of place besides people.
