Global Change

I think the next fifty years will change the world with positive effects and negative effects. Some major changes will be in technology and medicine. I think people will beome more and more curious with these advances and scientists wont just be just cloning animals but people, and advanced machines like flying cars will be made. Some of these changes could lead to disagreements between different people and countries. Even though some changes might be good for the world such as cure for cancer, i believe most advances will end in disaster and will make the world more horrible. I believe people should only advance to a certain point.
