What are Global Issues and why do I care?

I think that global issues are problems that are faced around the world. I care, because having global peace is an important value; it can make us feel united as a world, and puts aside differences. If everyone in the world is discriminated, Earth won't be at balance. However, if we manage to resolve these issues, the world could be even more diverse. Therefore, having Global Issues as a class will not only help us make the world better, but we could also change lives at an early age. This will encourage us to be leaders later on.
