What are global issues and why do I care?

Global issues are like global warming and war, global issues are all issues that are bad to all around the world, things that make everyone unhappy, things that can kill children and adults all over the world. I care because it is unfair to those who don't have money from their government or those who don't have their basic needs, which were supposed to be given by their local government as ordered by the UN(United Nations). All people should be equal and have peace, otherwise there WILL BE global issues! If we make all the world fair (which we won't, because some people just have to be evil to others) then we wont have to have money or anything (Which won't happen). The world will never be fair until there are none who cannot commit to peace, until there are no people that HAVE TO be evil or mean.
