If I were rich, I would have a personal tutor. I wouksnt go to school, because it would come to me. I woukd also have a nice house, and pets. And I would give back to my old neoghborhood.
My life would be different in a lot of ways but not just my life a lot of others too because I would donate money to the homeless. It would be different because we would get a pool and be able to afford things other cannot but we wouldn't buy fancy cars or huge houses because what's the point of that it just makes more to clean.
Environment A slimmed down because of the dam. There is now less water in Environment A then there was before. Environment B is flooded because of the dam. So in a way environment A and environment B kind of switched situations. I am not sure if this is correct but I hope it helps!
