The world is constantly changing, sometimes for the better, and sometimes for the worse. Making the world a better place is definitely an attainable goal, but I seriously doubt that this goal will be achieved in the next year, decade, or even century. Our world today has a colossal amount of things that need to be changed in order to improve it. Some goals are a little easier, like ending world hunger, but completely halting climate change or attaining world peace are tasks that sound much easier than they really are. In addition, I believe that as soon as one of the problems are solved, like stopping world hunger, then a new problem will arise, like food shortages or wars over which countries need food more. I may be a pessimist, but there are too many problems that need to be fixed and not enough time to do so.
